What does JPG to PNG conversion do?

JPG to PNG rewrites a JPEG as a lossless PNG at the same width and height. It does not magically restore detail JPEG already threw away — it stops further loss and gives you a PNG other tools accept.

This free JPG to PNG page on ImageStretcher runs in your browser. Upload, download PNG. No account, and the file stays on your device.

Need a different pair, a smaller file, or a new crop? Open Convert Image, Compress, or Crop on this site — each page has one job.

JPG to PNG vs compress vs crop

This page is only JPG to PNG. Compress reduces kilobytes. Crop trims the frame. Stretch changes width and height.

Stay here when you need PNG and want the same pixels. Switch tools when the problem is weight, framing, or stretch.

JPG to PNG FAQ

Does JPG to PNG improve photo quality?
No. JPG to PNG keeps the pixels you already have. JPEG compression stays in the picture; PNG just stores those pixels without another JPEG pass. Use this page when you need a PNG file, not a sharper photo.
Is JPG to PNG free?
Yes. No account required. Convert in your browser and download PNG.
Do you store my JPG file?
No. Convert and download stay on your device. We do not keep the PNG file on our servers.
JPG to PNG vs compress?
This page changes format to PNG. Compress shrinks file weight in KB or MB. Use compress when size limits are the problem.
