Convert TXT files to ODT free in your browser — no signup, no install, and the file is never uploaded to a server. ODT keeps full quality with no further loss.
Add your TXT file
Drag the TXT file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm ODT as the output
ODT is already selected as the output format on this page. Only the options this format actually supports show up, such as a page range or sheet selection.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the ODT file
When it finishes, download the ODT file. Converting multiple files gives you the option to download them together as a ZIP.
Pure character data with no formatting at all. It opens on any device or program and is the safest archival form for text that must stay readable decades from now.
The standard document format for LibreOffice and OpenOffice, and an ISO international standard. Being vendor-neutral makes it well suited to long-term archiving.
Yes. TXT to ODT conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the TXT file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
