JPG to PNG, without leaving your browser.
Moving from JPEG to lossless PNG is useful for further editing, archiving or print. IMGcon converts locally in your browser — no upload, no watermark, no quality loss from a second server pass.
Smaller files
PNG keeps every pixel intact: the right choice when the image is about to be edited, annotated or archived rather than published.
Web-ready output
Resize, crop and cap the file size in the same run. The result is ready for your site, store or CMS — no second tool needed.
Private by design
The conversion runs in your browser via the Canvas API. No server ever sees your images, and EXIF, GPS and camera data are stripped on the way.
How it works
Drop your JPG images
Drag & drop, browse or paste from the clipboard. Up to 30 files per batch — all processed in parallel.
Pick your settings
Output format is preset to PNG. Adjust quality, dimensions or cap the file size — or just hit optimize.
Download the PNG files
Grab each file individually or take the whole batch as a single ZIP. Compare before and after with the slider.
