Translation Services

Document Translation Services

Contracts, reports, manuals and technical files translated into 300+ languages by native speakers, checked by a second linguist, returned in your format.

Last reviewed

Document translation is the written conversion of a document into another language, keeping the meaning, the terminology and the layout of the original intact. Prism Linguistics translates contracts, reports, manuals, technical documentation, HR and policy files, presentations, PDFs and scans in more than 300 languages, using native-speaker translators with a second linguist checking the work. Send the file and you'll have a fixed quote within one working hour during office hours.

Most of what comes through this service is commercial and non-certified: the paperwork a business needs to sign a supplier, brief a factory, publish a policy or answer a tender. It's the written half of our translation services, and it has been the steadiest part of the workload since we started trading in 2013.

What we translate

Business document translation: the files we handle most

Translators are matched to the subject, not just the language pair. A commercial lawyer's contract and a plant engineer's method statement fail in completely different ways, so they don't go to the same person.

Contracts and agreements

Supplier contracts, distribution and agency agreements, NDAs, terms of business and employment contracts.

Reports and accounts

Board papers, annual reports, audit documents, tender responses and management reporting packs.

HR and policy documents

Staff handbooks, health and safety policies, codes of conduct, disciplinary procedures and induction material.

Technical documentation

Specifications, datasheets, method statements, test reports, drawing callouts and product instructions.

Manuals and handbooks

Operating manuals, installation guides, maintenance schedules and end-user guides for machinery and consumer goods.

Presentations and internal comms

Sales decks, training slides, intranet notices and email templates for multilingual teams and overseas sites.

Contract translation for commercial, supplier and employment agreements

Contracts are unforgiving. A defined term has to be translated the same way in clause 2 as it is in schedule 4, an obligation has to stay an obligation rather than drifting into a recommendation, and "reasonable endeavours" has no tidy equivalent in most languages. Getting any of that wrong doesn't show up until there's a disagreement, which is exactly when it costs the most.

So contract work goes to translators with a legal background, and the reviewer reads the translation against the source clause by clause rather than skimming for typos. Where a concept has no direct equivalent, we translate it and add a short translator's note instead of inventing a term. Defined terms are locked to a glossary before anyone starts typing, which matters when a 60-page distribution agreement between a UK importer and a manufacturer in Katowice needs a Polish document translation that both legal teams will actually sign off.

If the contract is heading for a court file or a solicitor's bundle rather than a boardroom, our legal translation services page covers that side, including Legal Aid Agency rates for eligible work.

Technical document translation for engineering and manufacturing

Technical documents are full of things that must not be paraphrased: torque figures, tolerances, part numbers, safety classifications, standards references. A translator who doesn't know the field will happily turn a specific term into a plausible general one, and the document quietly stops being usable by the engineer who needs it.

We match technical work to linguists who have worked in the sector, and we ask for whatever reference material you have: an existing translated manual, a parts list, a supplier glossary. Units are a common trap. If your English original mixes metric and imperial, tell us which convention the target market uses and whether you want conversions added in brackets or left alone. Same with decimal separators, which flip between a comma and a point depending on the country, and will make a spec sheet look wrong to a German or Romanian reader if nobody thinks about it. A Romanian translation of a test report is no use if the numbers read oddly to the person signing it off.

Manual and handbook translation

A manual has a job: someone follows it, step by step, usually while holding a tool. That makes structure as important as wording. We keep step numbering, warnings, cross-references and diagram callouts aligned with the original, so when step 7 says "fit the retaining clip (D)", the letter D still points at the right thing on the illustration.

Two practical requests before we start. Send the source file if you have it rather than only a flattened PDF, because callouts embedded in an image have to be rebuilt by hand. And tell us whether product names, model codes and trademarked terms should stay in English. Most manufacturers want them untouched, but not all, and it is much cheaper to decide that up front than to change 400 instances afterwards. For handbooks going to overseas staff we can supply an Arabic translation or any other language with the layout preserved page for page.

PDF and scanned document translation, and the formats we work in

We handle Word, Excel, PowerPoint, PDF, plain text, and most design and publishing formats. Editable files come back as editable files in the same format. PDFs come back as a matching PDF, or as Word if you'd rather have something you can edit.

Scans and phone photographs are fine and arrive constantly, often taken on a kitchen table with the corner of the page curling. We rebuild those documents by hand rather than running them through automatic text recognition and hoping, because the things that break recognition software are exactly the things that matter: stamps, faint carbon copies, handwritten amendments in a margin, tables with merged cells. The single limit is legibility. If a word truly cannot be read, we mark it illegible rather than guess, and we'll tell you before the job starts if a rescan would be worth the trouble.

Layout matching, so both versions can be read side by side

We mirror the original: same headings, same numbering, same table structure, same clause references. It sounds like a cosmetic point until you watch someone try to match paragraph seven of a translation against paragraph seven of the source under time pressure. Text length shifts between languages, so spacing moves a little, but nothing gets renumbered. Bilingual parallel-column layouts are available too, which some clients prefer for contracts and policies. Just ask when you request the quote.

Terminology consistency and translation memory for repeat work

For companies that send work regularly we build a glossary of approved terms and keep a translation memory on the account. Your product names, job titles and standard clauses then come back identically every time, whether it's a policy update this month or a new datasheet next year. It also saves you money, because a revised document is charged for the text that actually changed rather than the whole file again. Businesses running this way can read more on our business translation and interpreting page.

Document translation for business: who sends us work

The mix is broad, and it shapes how we work. In a normal week that includes:

  • Manufacturers and exporters translating specifications, manuals and supplier agreements for overseas plants and distributors
  • UK companies preparing tender responses and compliance documents for procurement outside the UK
  • HR teams rolling out handbooks, contracts and safety policies to a workforce that doesn't all read English comfortably
  • Local authorities and NHS trusts translating public information, letters and internal guidance into community languages
  • Solicitors and in-house legal teams sending correspondence, disclosure material and commercial agreements
  • Universities and research groups translating reports, protocols and collaboration paperwork
  • Individuals with a single document that has suddenly become important

Public sector clients want an audit trail and a named contact; commercial clients usually want speed and a price they can put in a budget line. We try to give both to everyone, and the same project manager stays with your job from quote to delivery so you're not re-explaining it to a queue.

How it works

How to order document translation: three steps

No account, no minimum order. Most jobs start and finish by email.

  1. 1

    Send the file and tell us what it is for

    Upload the document through the quote form or email it over. Tell us the target language, the deadline, and who will read the translation. A document for a supplier and a document for a regulator are edited differently.

  2. 2

    Approve a fixed quote

    We reply within one working hour during office hours with a fixed price, a word count and a delivery date. Longer files are priced per source word, and if repeated content from earlier work applies we say so in the quote.

  3. 3

    We translate, review and return it in your format

    A native-speaker translator with the right subject background does the work and a second linguist reviews it against the source. You get the file back in the same format, laid out to match the original as closely as the file allows.

What drives the cost of document translation

Longer documents are priced per source word, which is fairer than per page because pages vary enormously, and it means you can sanity-check a quote yourself before you agree to it. Four things move the number.

Word count is the obvious one. The language pair is the next: a common European language has a deep pool of UK-based translators and prices accordingly, while a rare language with a handful of qualified linguists in the country costs more, for the plain reason that there are fewer of them. Subject matter matters too, since dense legal or clinical text takes longer per page than an induction handbook. And the deadline: genuinely urgent work carries a premium, though we'll tell you honestly when waiting one more day would save you money.

Our pricing page publishes the ranges rather than a single headline rate, because a single rate would be wrong for half the jobs we quote. For your actual document the quote is free, fixed and back with you inside a working hour during office hours.

Confidentiality, NDAs and UK GDPR

A lot of this material is commercially sensitive before it is anything else: unsigned agreements, tender pricing, incident reports, personnel files. Every linguist works under a non-disclosure agreement, files are shared only with the people working on your job, and our handling is UK GDPR compliant. If your organisation has its own NDA, send it and we'll sign it before you upload anything.

Documents for the Home Office, a court or a university

Some documents need more than an accurate translation. If a UK body is going to accept it as evidence, it usually needs a signed statement of accuracy attached, and that's covered on our certified translation page rather than here. The most common cases have pages of their own: a birth certificate translation, an immigration document translation for a visa application, or a legal document translation bound for a tribunal. If you're unsure which category your document falls into, tell us who is receiving it and we'll say which you need.

Marketing, websites and software

Written documents are one thing; copy that has to sell or run in a browser is another. Print and campaign material belongs on our brochure and marketing translation page, live site content on website translation, and app or software strings on localisation.

Questions people ask

Document translation FAQs

What file formats can you translate?
We work with Word, PDF, PowerPoint, Excel, plain text and most common formats. Where a document is editable we return it laid out like the original. For scans and PDFs we recreate the layout as closely as we can. If you have an unusual format, send it and we will let you know.
Can you translate a scanned or photographed document?
Yes, and a large share of what we receive arrives that way. We rebuild the document rather than run it through automatic text recognition, so tables, headers and stamps end up where they belong. The only real limit is legibility: if a word, a signature or a handwritten note genuinely cannot be read, we mark it as illegible in the translation rather than guess at it.
Will the translation keep the same layout as the original?
That is the default. We mirror headings, numbering, tables and clause references so a reader can put the two versions side by side and follow them together. Where the target language runs longer or shorter than the English the spacing shifts a little, but the structure stays the same. If you need a bilingual layout with both languages in parallel columns, ask when you request the quote.
Do I need a certified translation or a standard one?
If the document is going to a government body, a court or a university, you almost certainly need a certified translation. For internal business use, marketing or general information, a standard translation is usually fine. If you are not sure, tell us what the document is for and we will say which you need.
How quickly can you turn a document around?
A typical translator handles around 2,000 to 2,500 words a day, plus time for the second-linguist check. A short document can often be ready within a day or two. For longer or urgent work we can put a team on it, though splitting a file across translators needs a shared glossary to keep it consistent. Give us the word count and your deadline and we will be straight with you.
What affects the cost of document translation?
Four things: the word count, the language pair, how technical the material is, and the deadline. Longer documents are priced per source word, and a common European language costs less than a rare one because the pool of qualified translators is bigger. Dense legal or clinical text sits higher than a staff handbook. Our pricing page sets out honest ranges, and the quote for your actual file is free and fixed.
Can you keep our terminology consistent across documents?
Yes. For companies that send work regularly we build a glossary of your approved terms and keep a translation memory on your account, so product names, job titles and standard clauses come back the same way every time. It also keeps costs down, because a revised document only charges you for the text that actually changed.
Is my document kept confidential?
Yes. Every translator works under a non-disclosure agreement and we handle your files in line with UK GDPR. Documents are shared only with the linguists working on your job, and we are happy to sign your own NDA before you send anything sensitive.
