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

2. API Format Matrix
curl -X POST https://api.convertchester.com/v1/convert \
-F "file=@document.png" \
-F "to=jpeg"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
PNG .png
Lossless raster image with transparency — the format for logos, screenshots and cut-out visuals.
JPEG .jpg
Lossy compressed image without transparency — the photography format, where file size matters more than the exact pixel.
What this conversion changes
Going from PNG to JPEG is not neutral. What the service can tell you before you drop anything:
- PNG stores transparency, JPEG does not: transparent areas are flattened onto a white background.
- PNG keeps every pixel, JPEG compresses with loss: re-encoding discards detail, and that detail does not come back.
The same conversion, in one line
The browser and your backend call the same endpoint, and get the same response.

Is converting PNG to JPEG 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 PNG?
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.
