Why MixTranslate

Translate documents precisely, preserving layout

Most document translators dump you a wall of text. MixTranslate keeps Office structure, previews the result, and handles structured files like JSON, CSV, and SRT without breaking the format.

Translate documents into 150+ languages

Translate documents into 150+ languages

Send a proposal to a client in Korean, a deck to a team in German, or subtitle cues into Spanish. The language you need is already here.

Get started
The document formats you actually use

The document formats you actually use

DOCX, PPTX, XLSX, Markdown, TXT, HTML, JSON, CSV, and SRT. Drop the file in as it is — no converting a slide deck into a PDF just to get a translation.

Get started
Your file is parsed in the browser

Your file is parsed in the browser

Word, PowerPoint, and Excel are unpacked on your machine. MixTranslate extracts the text locally, sends only those segments for translation, and rebuilds the file in your browser — the original document never gets uploaded as a blob.

Get started
Word, PowerPoint, and Excel keep their layout

Word, PowerPoint, and Excel keep their layout

Translated text goes back into the original paragraphs, slides, and cells. Tables still line up, decks still present, and spreadsheets still calculate around the words you changed.

Get started
Preview before you download

Preview before you download

Check the translation in Preview or Raw before you send the file. Catch a tone miss or a term that slipped, switch models, and run it again — then download when it looks right.

Get started
JSON, CSV, and SRT stay structured

JSON, CSV, and SRT stay structured

App strings, subtitle cues, and spreadsheet-like data need more than a blob of prose. MixTranslate translates the values and keeps the structure you still have to ship.

Get started
Choose from 20+ AI models

Choose from 20+ AI models

A contract, a pitch deck, and a changelog do not need the same voice. Pick from ChatGPT, Claude, Gemini, DeepSeek, Grok, and more, then switch if the first pass is off.

Get started
Your terms and tone, locked in

Your terms and tone, locked in

Lock brand names, legal phrasing, and product language in a glossary so every file — and every language — renders them the same way. Then set the tone without rewriting the draft.

Use Cases

Translate the files your work already lives in

A contract in Word, a deck in PowerPoint, strings in JSON. Upload the file and get a translated version you can preview, download, and share.

Contracts & business docs

Keep clauses, headings, and signature blocks in place while the language changes. Glossary locks defined terms so a party name does not drift mid-document.

Pitch decks & presentations

Translate slide copy without rebuilding the deck. Layout stays, so you can present in another language without moving every text box by hand.

Spreadsheets & reports

Labels, comments, and narrative cells get translated while the grid stays usable. Review the preview before you send the workbook.

Subtitle files

Drop in an SRT, get translated cues back. Timing stays so you can caption a video without re-cutting the track.

App strings & JSON

Localize keys without breaking the file your build expects. MixTranslate translates the values and leaves the structure you still have to ship.

Knowledge base & Markdown

Docs, READMEs, and internal guides in MD, TXT, or HTML come back as files you can commit or publish — not a screenshot of a translation box.

How to use it

Upload, translate, download

Three steps from the file on your desk to a translated file you can send.

  1. 1

    Upload your document

    DOCX, PPTX, XLSX, Markdown, TXT, HTML, JSON, CSV, or SRT. Drop the file in and pick from 150+ languages.

  2. 2

    Pick a language and a model

    Choose one of 20+ AI models, attach a glossary if you have product or legal terms, and set the tone for the audience.

  3. 3

    Preview and download

    Check Preview or Raw, switch models if a passage is off, then download the translated file with the layout you started with.
