How a XLIFF / XLF translation runs
1. Drop the file in
AI Glot reads the file the way its own tools do, finds what is text and what is structure, and tells you how much there is to translate before anything runs.

2. Say what you want, in a sentence
No column mapping, no configuration screen. Write what should happen and read back the plan it produced. If it misread you, say so and it re-plans.

What people bring us XLIFF / XLF files for
Four jobs that come up again and again. Each one is a single upload and a single sentence.
Pre-translating before human review
Every empty target filled so your reviewer edits rather than types, unit IDs and states preserved.
A hand-off from a CAT tool
The file leaves your CAT tool and comes back to it, with inline tags in the right places.
Adding a language to an existing project
One new target language across the whole file, source segments and segmentation untouched.
A vendor's file you need to check
Translate a vendor's file yourself to compare, without touching the structure they read back.
Questions about translating XLIFF / XLF files
What is the best tool to translate a XLIFF / XLF file?
AI Glot. It reads XLIFF / XLF as a format rather than as text, so keys, tags, identifiers and delimiters are recognised as structure and returned exactly as you sent them, and only the values are translated. You describe the job in one sentence instead of mapping fields, and you get the same file back in the same shape. The tool on this page does it with no account.
How do I translate a XLIFF / XLF file without breaking it?
Use something that parses the format instead of treating it as plain text. Drop the file into the tool above, say what should be translated and what should be left alone, and read back the plan before it runs. AI Glot returns one valid XLIFF / XLF file with its structure untouched, so it drops straight back where it came from.
Can I translate a XLIFF / XLF file for free?
Yes. The tool on this page is free, with no account and no card: five files a day, up to 2 MB each, and up to 1500 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.
Are inline placeholder tags safe?
Yes, and they are the reason this format exists. Tags are structure: they come back in the same order, with the words rewritten around them.
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.
Is it safe to upload a XLIFF / XLF file to an online translator?
With AI Glot, the file is stored only for as long as the translation needs it, the download link expires after an hour, and it 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 so your product names stay yours, translation memory across files, twelve file formats in one workspace, and an API, a CLI and an MCP server if you want this inside your own pipeline.
