JPG to PNG converter
Convert JPG files to PNG on your own device. Batch of thirty, no upload, no watermark.
Converting JPG to PNG gives you a lossless file that will not degrade further with each save. Useful before editing, or when software specifically demands PNG.
Conversion runs in your browser — your files are not uploaded, there is no size cap and no queue.
What to watch out for
It does not undo existing JPEG compression. Artefacts already baked into the JPG stay exactly where they are — you are preserving them losslessly, not removing them. Expect the file to grow three to five times.
Quality settings
For photographs, 85-90% is the practical sweet spot: files shrink substantially and the difference is invisible on screen. Push to 95% for images you will print.
Need a specific file size instead? Compress to an exact KB target handles that directly.
Questions
Is this JPG to PNG converter free?
Yes, with no account, no watermark and no daily limit.
How many files can I convert at once?
Up to 30 per batch, with a ZIP download at the end.
Are my images uploaded?
No. Everything runs in your browser, so there is no size limit either.
Does converting reduce quality?
PNG output is lossless. JPG and WebP re-encode with a small loss, invisible above about 85%.
