JPG to PNG Converter Guide
Convert JPG and JPEG images to PNG while preserving their decoded pixel dimensions.
Private browser processing

- Create a lossless editing copy
- Convert a batch without changing dimensions
Formats and results
JPG and JPEG input; PNG output with the same decoded width and height.

Know before you start
- PNG output does not restore quality lost in the JPG.

If the result is not right

Questions
JPG to PNG help and privacy.
Does JPG to PNG preserve dimensions?+
Yes. The PNG uses the decoded JPG width and height.
Will JPG to PNG remove compression artefacts?+
No. It changes the format but cannot recover detail already lost in the JPG.
Why can the PNG file be larger?+
PNG uses lossless compression, so photographic images often require more storage than JPG.
