BMPtoTXT
Convert BMP to TXT
Up to 100 files at once. Mixed formats are fine.
They convert one after another and download together as a ZIP.
You can convert BMP to TXT free and without an account: drop the file above and the TXT is ready to download in a second or two. The conversion happens inside your own browser, so the file is never uploaded — it works on Windows, Mac, Linux, iPhone and Android, and keeps working with the network switched off.
Where it runs
In your browser. The file is never uploaded.
Lossy
Some detail is traded for size. TXT cannot hold everything a BMP can.
File size limit
Up to 100 MB per file, free, without an account.
Worth knowing
The text is read by pattern recognition, so it is a best guess and not a transcript. Clean, straight, well-lit type at a decent resolution comes out close to perfect; a photograph taken at an angle, a faint fax, an unusual typeface or handwriting will produce mistakes. Always read the result against the original before relying on it. The language setting matters — text read with the wrong one comes back as confident nonsense rather than as an error.
What BMP and TXT are for
Uncompressed Windows bitmap. Huge files, still produced by scanners and older software.
Characters and nothing else. Will still open in fifty years.

BMP to TXT: common questions
Are my BMP files uploaded anywhere?
No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and convert something. You will see the page load, plus the analytics and advertising the site is paid for with — and nothing carrying your file.
Is converting BMP to TXT free?
Yes. There is no account, no watermark and no limit on how many files you convert — it runs on your own machine, so it costs us nothing to let you. Files up to 100 MB are handled in the browser.
Does converting BMP to TXT lose quality?
BMP and TXT describe content in fundamentally different ways, so the conversion is a reconstruction rather than a copy. The result is faithful, but not byte-for-byte equivalent. The text is read by pattern recognition, so it is a best guess and not a transcript. Clean, straight, well-lit type at a decent resolution comes out close to perfect; a photograph taken at an angle, a faint fax, an unusual typeface or handwriting will produce mistakes. Always read the result against the original before relying on it. The language setting matters — text read with the wrong one comes back as confident nonsense rather than as an error.
Do I need to install anything to open TXT files?
No installation is needed for the conversion itself — it runs in the browser you already have. Opening the TXT afterwards needs whatever software normally handles Plain Text on your device.
