Convert JPG to PNG
Free online JPG to PNG converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert JPG to PNG?
Convert JPG to PNG when you need lossless storage of an already-saved image, or when you need to add transparency. JPG compression artifacts will still be visible. Converting to PNG doesn't restore lost detail.
Tips
- PNG files will be larger than the source JPG. That's the tradeoff for lossless storage.
- If your goal is to edit and re-save without further loss, PNG is the right choice.
PNG stops further damage. It doesn't undo what's already there
JPG throws away image detail every time it's saved, and that loss is permanent once it happens. Re-saving as PNG afterward locks in whatever the JPG already lost. It won't remove blocky artifacts around hard edges, it won't sharpen blur, and it won't bring back fine texture the JPG compressor smoothed away. What PNG gives you is a stopping point. From here on, every further edit and re-save keeps every pixel exactly as it is, with no more generation loss stacking on top.
Frequently asked questions
How do I convert JPG to PNG?
Drop your JPG file into the converter above, adjust the quality if needed, and click "Convert to PNG". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the JPG to PNG conversion lossless?
Yes. PNG is a lossless format. The conversion preserves all visual information from the source file.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my JPG files uploaded to your servers?
No. All JPG to PNG conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
Should I always convert my JPGs to PNG before editing them?
It's a reasonable habit if you plan to edit the same image multiple times and re-save it repeatedly. Each JPG save degrades the image a little more. That effect is called generation loss. Converting once to PNG before you start editing means your working file stops accumulating that damage on every save. It isn't necessary for a single edit-and-export pass, where saving straight back to JPG at a good quality setting rarely causes a visible difference. It matters most for images you'll open, tweak, and save many times.
