01 / GUIDE
How to use JPG to PNG
- Choose a JPG or JPEG image.
- Confirm the preview and destination file name.
- Convert and compare the PNG output size with the source.
02 / DETAILS
About this conversion
Re-encode JPEG photos as PNG locally. This changes the file format, but it cannot restore detail lost in the original JPEG.
PNG stores pixels losslessly after conversion, but a source JPEG has already passed through lossy compression. A PNG output may be larger, even though the format itself preserves the decoded pixels.
Limits to know
Each input is limited to 40 MiB and 16 megapixels so the browser has a safer memory budget. Very large dimensions can still exceed the memory available on a phone.
Processing runs in this browser. Originals are not overwritten, and the output size is measured in bytes before download. Keep a backup of important files.
03 / FAQ
Questions people ask
Does PNG make a JPG sharper?
No. Changing format cannot recover detail lost when the JPG was created.
Why can the PNG be bigger?
PNG preserves the decoded pixel data without JPEG-style loss, which often takes more bytes for photographs.
