JPG vs PNG
JPG is best for photos; PNG is lossless and best for graphics, screenshots and images you'll edit repeatedly. Converting JPG to PNG doesn't restore detail lost to JPG compression, but it stops further loss every time you edit and save, and some upload forms and design tools require PNG.
How to use it
- Choose or drop one or more JPG files.
- Each file is converted instantly in your browser.
- Download individually or as a ZIP.
Expect the PNG to be larger than the JPG—that's normal for lossless formats.
FAQ
Does PNG make the background transparent?
No, the image keeps its original background. Transparency has to be added in an image editor.
Is there a file limit?
No hard limit. Very large images (over ~50 megapixels) may exceed your browser's canvas limit.
