TMX editor
Open a translation memory and fix it unit by unit: search, edit target segments with their tags, delete what you don't want, and download a TMX your CAT tool imports cleanly.
Your files never leave your computer. The memory is opened in your browser and nothing is uploaded.
How it works
1. Open your memory
Drop a TMX, an XLIFF or a Trados .sdltm. It's read in your browser, with every language it contains.
2. Edit units
Search and filter, then edit the target text. Tags show as numbered chips like in memoQ, so they don't get broken. Any step can be undone.
3. Save a TMX
Review every change before you download. Units you didn't touch stay exactly as they were, byte for byte.
Frequently asked questions
Is the TMX editor free?
Yes. No sign-up and no limit on edits. Files up to 500 MB work on a computer.
Is my translation memory uploaded anywhere?
No. The file is read and edited in your browser and never reaches our server, so you can use it with memories covered by an NDA.
How are tags shown and edited?
Like in memoQ: paired tags appear as numbered chips such as {1> and <1}, standalone tags as {2}. Chips can be deleted, or moved by cutting and pasting them, but not broken, and Alt+Insert adds the next tag from the source. The original tag XML is written back when you save.
What happens if I close the tab before saving?
Your edits are autosaved in this browser. Open the same file again and the editor offers to restore them. Nothing is stored on a server, and autosaved edits are deleted after 30 days.
Can I edit Trados .sdltm or XLIFF files?
Yes. Drop an .sdltm memory or an XLIFF (SDLXLIFF, MQXLIFF and others) and it opens as a translation memory. You edit it and download a TMX; the original file isn't changed.
