How to convert JPG to PNG
- Step 01
Add your JPG file
Drop one or many JPG files onto the converter, or browse from disk. Stay within the on-device size limits shown under the drop zone — oversized files are rejected so your tab does not freeze.
- Step 02
Tune and convert
Set quality if the PNG encoder offers it, then start the conversion. Pixels are processed on this device — nothing is uploaded.
- Step 03
Download PNG
Download your new PNG file immediately. Multiple outputs pack into a single ZIP archive.
Why convert JPG to PNG
JPG compresses photos aggressively and cannot keep transparent pixels. Converting to PNG rebuilds a lossless raster, so soft edges, text overlays, and any newly added alpha channel survive without another round of JPG artifacts.
When to use this tool
- You need a transparent background for a logo or product cutout that started as a JPG.
- You plan to edit the image further and want to avoid stacking JPG compression damage.
- A design tool or print workflow asks for PNG instead of a camera JPG.
Good to know
- PNG files are usually larger than the original JPG — that is expected for lossless output.
- Transparency is only useful if you add or preserve an alpha channel after conversion.
- Repeated JPG→PNG→JPG round-trips still cannot recover detail already discarded by JPG.
- Browser limit: about 40 MB per image, up to 20 files per batch. Very large dimensions are scaled down automatically.
- Need a bigger file? For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.

Yes. Browser Convert does not charge for JPG → PNG, add watermarks, or require an account.
Will JPG to PNG keep image quality?
