Your images never leave your browser
All processing happens locally on your device. Nothing is uploaded to a server, stored, or tracked.
Move a photographic JPG to lossless PNG when you need pixel perfect storage or to add transparency for editing. PNG preserves every pixel exactly but creates larger files than JPG, so use it for masters and graphics.
How it works
Why convert JPG to PNG?
Move a photographic JPG to lossless PNG when you need pixel perfect storage or to add transparency for editing. PNG preserves every pixel exactly but creates larger files than JPG, so use it for masters and graphics.
How PNG compares to JPG
PNG is generally higher quality than JPG. The main differences are file size, quality characteristics, and transparency support.
Quality recommendations
For PNG output, start at the lossless preset and adjust to taste. A lower quality setting shrinks the file further; a higher one keeps more detail. Keep the original JPG file for archival edits.
Is conversion private?
Your JPG is decoded and re-encoded to lossless PNG in your browser. No image data is ever sent to a server.
Batch convert JPG to PNG
Select several JPG photos and convert them all to lossless PNG at once. Free, no sign up, batch ZIP download, and your files never leave your device.
Frequently asked questions
Does JPG to PNG lose quality?
No. PNG is lossless so your pixels are preserved exactly. The file grows because no detail is discarded.
Why would the PNG be bigger than the JPG?
PNG stores every pixel losslessly while JPG discards detail to save space. Photos converted to PNG often double in size.
Can converting JPG to PNG add transparency
A converted PNG can carry transparency going forward but it cannot magically make the original photo background transparent. You need to remove the background first, then save as PNG.
