JPG to PNG converter
Turn JPG, the standard compressed format for photos, into PNG, a lossless image format with transparency. Free, private and fast: everything happens in your browser.
How it works
- 01
Drop your files
Videos, audio, images, or a whole folder. Nothing is uploaded: the files are read straight from your disk.
- 02
Pick a format
Choose a target for each type, or tap a preset like “Small video to share”. Tune size and quality if you want.
- 03
Save the results
FFmpeg runs in your browser. Preview each file, see how much space you saved, and download one by one or as a ZIP.
JPG to PNG: questions
How do I convert JPG to PNG?
Drop your JPG files into the box above, check that PNG is selected, and press Convert. When it finishes, save each file or download them all as a ZIP.
Is it safe to convert JPG files here?
Yes. Your JPG files are converted on your own device by FFmpeg running in the browser. Nothing is uploaded to a server.
Is it free? Is there a file size limit?
It is completely free with no sign-up and no watermark. The only limit is your device’s memory: a few hundred MB per file works well on most computers. Very large videos may run out of memory in the browser.
Can I convert many files at once?
Yes. Drop a whole batch or pick a folder. Each type of file can go to its own format, for example images to WebP and videos to MP4, and you can download everything as one ZIP that keeps your folder structure.
