About JPG to PNG Converter
Converting JPG to PNG swaps a lossy container for a lossless one. The pixels you have now are copied exactly and frozen — every future save keeps them intact, instead of compounding new JPG artifacts each time the file is re-encoded. That is why screenshots, logos, UI mockups and anything heading into a design tool or CMS media library are usually asked for as PNG.
Drop up to 15 JPG or JPEG files (5MB each). Output is fixed to PNG, so hit Convert immediately. Files are processed in your browser and appear with a size readout — expect them to grow, often two to five times larger than the source. Save them individually or grab everything as one ZIP.
Two things people expect from this conversion that it cannot do. It will not restore detail already destroyed by JPG compression — blocking around text and halos around high-contrast edges are baked into the pixels and stay in the PNG. It will also not add transparency, because there is no alpha data in a JPG to recover; your PNG will be fully opaque. What it does deliver is a stable master file. If your goal is a smaller file rather than an editable one, WebP is the better target.

Frequently Asked Questions
Why convert JPG to PNG instead of keeping the JPG?
PNG is lossless, so once converted you can re-save or re-edit the image repeatedly without compounding compression artifacts the way repeated JPG saves do. It's also the format most design tools and CMS media libraries expect for logos and screenshots.
Will converting to PNG add transparency to my JPG?
No. JPG has no alpha channel, so there's no transparency data to recover — the PNG output will be fully opaque, just stored losslessly instead of with JPG's lossy compression.
Does converting JPG to PNG improve image quality?
It stops further quality loss from future saves, but it can't restore detail already lost to JPG's compression — the pixels are copied exactly as they exist in the source file.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser; images never leave your device.
