JPG to PNG Converter
Convert JPG images to PNG right in your browser.
Convert JPG images to PNG, entirely in your browser. Conversion runs locally with the Canvas API, so your files never leave your device. You can also work on several images at once: add up to 20 files, apply the same settings to all of them, and download the results one by one or together as a ZIP.

Frequently asked questions
Are my images uploaded to a server?
No. This converter works entirely in your browser, so your files never leave your device and nothing is stored.
Will the image lose quality?
No. PNG is lossless, so the converted image keeps its full quality.
Can I do several images at once?
Yes. Add up to 20 images (25 MB each, 150 MB in total) and they are processed in your browser, a couple at a time so your device stays responsive. Each image gets its own download, and "Download all as ZIP" collects them into one archive. If one image can't be read, it is flagged on its own row and the rest are still processed.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
