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

-F "to=bmp"Files processed on-the-fly in RAM and discarded instantly.
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
PDF .pdf
Fixed-layout document, meant to be read and printed identically rather than edited.
BMP .bmp
Uncompressed image, readable everywhere — large files, but no exotic decoding to worry about.
What this conversion changes
Going from PDF to BMP is not neutral. What the service can tell you before you drop anything:
- PDF stores transparency, BMP does not: transparent areas are flattened onto a white background.
- A PDF can carry several pages; a BMP carries one. Only the first is returned.
- Each page becomes an image: the text is no longer selectable or searchable.
The same conversion, in one line
The browser and your backend call the same endpoint, and get the same response.

Is converting PDF to BMP 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 PDF?
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.
