Questions
Will converting make my image look better?
No converter can add detail that the JPG compression already removed, but PNG will not lose any more quality — it stores the pixels exactly as they are now.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
