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

Exact same multipart response from browser or your backend.
Both formats
JPEG
.jpg
Lossy compressed image without transparency — the photography format, where file size matters more than the exact pixel.
Fixed-layout document, meant to be read and printed identically rather than edited.
What this conversion changes
Going from JPEG to PDF is not neutral. What the service can tell you before you drop anything:
- JPEG and PDF 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.
curl -X POST https://api.convertchester.com/v1/convert \
-F "file=@document.jpg" -F "to=pdf"Is converting JPEG to PDF 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 JPEG?
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.
