Convert JPEG to PNG
Drop JPEG or JPG files and download lossless PNGs at the same dimensions. PNG is the right target when a tool or pipeline needs PNG, or when you want a lossless container for further edits.
Converting does not improve the picture: PNG cannot undo the compression artifacts already in a JPEG. It stops new loss from here on, which matters once you start editing and re-saving.
What you get
- Lossless output. PNG stores every pixel as decoded, so repeated edits and saves add no further loss.
- Same size in pixels. Width and height are unchanged.
- No transparency. JPEG has no alpha channel, so the PNG is opaque. Nothing becomes transparent by converting.
Larger files are normal
For photographs, the PNG is typically several times larger than the JPEG, because PNG does not use lossy compression. For screenshots, diagrams, or flat graphics the gap is smaller. If file size matters more than lossless editing, keep the JPEG or convert to WebP instead.
Batch and privacy
Add multiple files, convert, and use Download all as ZIP for the whole set. Conversion runs in your browser through Web Workers, in parallel; nothing is uploaded. Re-encoding from pixels also drops the original EXIF metadata.
