How a XLIFF / XLF translation runs
1. Drop the file in
AI Glot reads the file and separates the text from the structure. It then tells you how much there is to translate, before anything runs.
mobile-app.xliffmarketing-site.xlfrelease-notes.xlf
2. Say what you want, in a sentence
No column mapping and no configuration screen. Write what you need, then read the plan it produced. If it misread you, say so and it plans again.

What people bring us XLIFF / XLF files for
Four jobs that come up again and again. Each one is one upload and one sentence.
Pre-translating before human review
Fill every empty target in one run. Your reviewer edits instead of typing, which is far less work to ask for.
A hand-off from a CAT tool
Send the file out of your CAT tool and back in. Unit ids come back as they went and inline tags return in the right places.
Adding a language to an existing project
Add a language to a finished project. The source segments and the segmentation do not move.
A vendor's file you need to check
Check a vendor's delivery by translating it yourself. Compare both versions before you accept the work.
Questions about translating XLIFF / XLF files
What is the best tool to translate a XLIFF / XLF file?
AI Glot. It translates a full XLIFF / XLF file in one job, at a quality you can steer with a glossary and a plain-English brief. You describe what you need. You do not map fields or split the file. The tool on this page runs it with no account.
How do I translate a XLIFF / XLF file without breaking it?
Use a tool that reads the format instead of the raw text. Upload the file above and say what to translate. Read the plan, then run it. AI Glot returns one valid XLIFF / XLF file, so it goes straight back where it came from.
Can I translate a XLIFF / XLF file for free?
Yes. The tool on this page is free. No account and no card. Five files a day, up to 2 MB each, and up to 5,000 words translated per file. Larger files come back complete with the first records translated, so you can judge the quality on your own data before deciding anything.
What happens if my XLIFF / XLF file is bigger than the free limit?
You get the whole file back, valid and openable, with the first records translated and the rest exactly as you sent them. It is deliberately not truncated: a cut-off XLIFF / XLF file would not open, and a sample you cannot open tells you nothing. An AI Glot account removes the limit.
Which XLIFF versions are supported?
Both 1.2 and 2.0. The version is detected from the document rather than assumed. In 2.0, the first segment of each unit is the one translated.
Are inline placeholder tags safe?
Yes. Tags such as g, x, ph, pc and mrk travel with the words they belong to and are rebuilt from the source's own elements, so the result is valid XLIFF with every tag in place. Placeholders written in the text, like {count} or %s, are protected by your instructions.
Can I skip units that are already translated?
Yes. Say so in your instruction and the plan will report how many units it is leaving alone, so you only pay for the new ones.
What about Trados, memoQ and Phrase files?
Trados .sdlxliff, memoQ .mqxliff and Phrase .mxliff files have their own page. Locked segments are never touched, and results are marked as unconfirmed machine drafts for you to confirm in the tool.
Is it safe to upload a XLIFF / XLF file to an online translator?
AI Glot keeps the file only as long as the translation needs it. The download link expires after an hour. The file is deleted afterwards. Nothing you upload is used to train any model. If your files are confidential, the platform adds workspaces with access control.
What do I get with an AI Glot account?
No size limit and no daily limit. Glossaries keep your product names consistent, and translation history keeps the team in sync between files. More than 35 formats share one workspace, and an API, a CLI and an MCP server put the same engine in your own pipeline.
