Convert BMP to PNG
Drop your BMP, get a PNG. The file is processed in memory, returned with its SHA-256 fingerprint, then forgotten — nothing is kept on our servers.

Format verified from header bytes, never trusted from extensions.
Cryptographic hash provided for complete file auditability.
Exact same multipart response from browser or your backend.
Both formats
BMP .bmp
Uncompressed image, readable everywhere — large files, but no exotic decoding to worry about.
PNG .png
Lossless raster image with transparency — the format for logos, screenshots and cut-out visuals.
What this conversion changes
Going from BMP to PNG is not neutral. What the service can tell you before you drop anything:
- BMP and PNG carry the same kind of information: this conversion asks for no particular trade-off.
The same conversion, in one line
The browser and your backend call the same endpoint, and get the same response.

Is converting BMP to PNG free?
Yes, in the browser and without an account. The API has a free quota; a refusal is never counted.
Are my files kept?
No. The file is processed in memory then forgotten. Logs carry only its SHA-256 fingerprint and its size — never its name or its content.
What happens if my file is not really a BMP?
The format is read from the file’s bytes, never from its extension. An unrecognised file gets an explained refusal with a stable code — and that refusal is not billed.
