JPG to PNG Converter — Free, No Upload | Input and conversion guide
Decodes JPG pixels and encodes a new PNG for subsequent editing. This is not merely a container rename, and existing JPEG losses and opaque backgrounds remain.
- Runs in your browser
- Nothing is uploaded
- No signup; device limits apply
How to use this tool
Choose the JPG and confirm later editing can accommodate a larger PNG file.
Results and examples
Open the PNG to compare color profile and size, then check any upload limit.
Worked example
Convert a JPEG instruction image to PNG before adding arrows, while recognizing that the existing lettering has not been restored.
Limitations
- PNG encoding does not recover color edges or fine detail already lost in JPEG.
- An opaque JPEG remains opaque; selecting PNG does not automatically create transparent regions.
Data handling
Processing stays in the current browser tab; the site does not upload tool input for the calculation itself.
