Guide
How it works, and what it costs you.
Traxlate runs on your machine. That has real consequences — a download, some disk space, and a first run that takes a moment — and this page is about being straight with you on all of them before you rely on it.
Start here
- Open the translator and press Install pack.
- Wait for the download — about 1.4 GB, once. It resumes if interrupted.
- Translate. From then on it works offline, with nothing sent anywhere.
You do not need an account to do any of that. Translation is free and unmetered because it runs on your hardware, not ours.
What gets installed
| What | Size | Why |
|---|---|---|
| Language pack | 1.4 GB | The translator itself. A lighter 1.1 GB version installs automatically on devices with less memory. |
| Second opinion | 450 MB | A second engine that disagrees with the first. This is what stops a fluent-but-wrong sentence reaching you. |
| Quality check | 125 MB | Scores the candidates against your source so the closest one wins. |
They live in your browser’s storage, not in a folder you have to manage. Clearing site data removes them, and re-installing costs the same download again.
Roughly 2 GB of free space during install, and a current desktop browser. On a device that cannot run it, the page says so plainly rather than failing halfway through.
What runs where
This is the part worth understanding, because it is the whole product:
- On your device, always: text, documents, PDFs, subtitles, dubbing, your translation memory, glossary and history. These have no path to our servers — not a setting, an absence of code.
- Only if you say yes: if you have not installed a pack, we can translate on our server instead. You are asked before anything is sent, and the answer is remembered in Settings.
- By definition: downloading a pack, and any text you deliberately send to a human translator.
Every result is labelled with where it ran. The chip on the result never lies about that.
The tools
Text
/translate — type, paste or speak. Lists and line breaks keep their shape, so a bulleted list comes back as a bulleted list. Ctrl+Enter translates.
Documents
/documents — .docx, .srt, .vtt, .txt, .md, .csv. Formatting survives: you get the same file back, translated.
PDFs
/pdf — page by page, and it remembers where you stopped, so a long document survives closing the tab. Scanned pages are read with OCR on your device. Up to 50 MB per file.
Subtitles
/subtitles — drop in audio or video (.mp3, .wav, .m4a, .mp4, .mkv and friends) and get timed captions. The media never leaves your machine.
Dubbing
/dub — a new voice track timed to the original, with the original audio ducked underneath. Also entirely on your device.
Human translation
/human — when being wrong is expensive. Priced per word, quoted before you commit. This is the one part that leaves your device, and the page says so before you order.
Getting more out of it
The review desk
/desk is where a translated document gets checked before you use it: every segment side by side with its source, fix what is wrong, approve what is right, then export the same file back. Translate a document first, then press Open in Desk.
Corrections are remembered
When you fix a translation in the review desk, that correction is saved. The next time the same sentence appears — in any job — Traxlate offers your version instead of translating it again. It is why the second document of a set is faster and more consistent than the first.
This lives in your browser, like everything else. It is not uploaded, and it is not shared with other users.
The glossary forces your terms
A glossary entry is not a suggestion. Add one for a language pair and the term is forced into the output when you retranslate a row — useful for a product name that must never be translated, or a term your industry renders one specific way.
Subtitles and dubbing
Subtitles export as .srt or .vtt, so they drop straight into a video editor or a player. Dubbing exports a .wav voice track timed to the original speech, with the original audio ducked underneath rather than replaced — you mix it in yourself, which means you keep control of the result.
Long PDFs
A PDF translates page by page and the progress is saved as it goes, so closing the tab does not lose the work — reopen the job and it continues. Files up to 50 MB. If yours is larger, split it and translate the parts; each is remembered separately.
Shape survives
Bullet lists, numbered lists and line breaks come back in the same shape you sent them. You do not need to translate a list one line at a time.
Languages
66 languages. If a language is not in the list, it is not supported — the app refuses rather than guessing badly, which we think is the less annoying of the two failures.
What the subscription is for
Translation is free. $5.99 a month adds encrypted sync between your own machines and the local API at full speed, on one device — a second device needs its own subscription.
Cancelling never switches off a pack you already installed. Pricing · Terms
When it goes wrong
Machine translation can be wrong in ways that read perfectly. Traxlate argues with itself and checks the winner before showing you anything, and it warns when it is unsure — but it is not infallible, and for legal, medical or safety text you should use a human.
