Convert PNG to JPG Online — Free
PNG is great for graphics with transparency but huge for photos. Converting to JPG can shrink the file 5-10× with no visible difference. ReFile flattens transparency to white (or any color you specify) so the JPG looks right.
- No signup to try
- Sandboxed processing
- Files deleted in 24 h
What this does
- Default: 92% quality JPG, white background where transparent
- Pick a background — 'JPG with black background'
- Pick quality — 'JPG at 80%' (smaller, still good)
How it works
- 1
Upload your PNG
Drop it above, or click to pick from your device. We validate the format immediately — no spinning on a file we can't process.
- 2
Run the conversion
The recipe runs in an isolated cloud sandbox — same as every other ReFile job. No AI guessing involved; it's a hand-written command that does one thing.
- 3
Download the JPG
Result lands in seconds. Files auto-delete from our servers after 24 hours; signed download URLs expire in the same window.
Frequently asked
- Won't I lose the transparent background?
- Yes — JPG doesn't support transparency. ReFile flattens to white by default. Specify any other color in your prompt ('with black background', 'with #f5f5f5 background').
- When should I keep PNG instead?
- When the image has transparency, large flat areas of color (logos, screenshots, line art), or needs to be lossless. JPG shines for photographs.
