About PNG → JPG
Flatten transparent PNG files onto a configurable background and export a quality-controlled JPEG entirely in Canvas.
PNG to JPG composites transparent pixels onto the selected background before JPEG encoding. This avoids the unpredictable black or transparent appearance that can result when an alpha channel is simply discarded.
How to use it
- Enter or select your source data.
- Adjust the available options and run the tool.
- Review, copy, or download the result.
Common use cases
- Prepare transparent product images for systems that accept only JPEG.
- Flatten a logo or diagram onto a known page background.
- Reduce photographic PNG files when lossless storage is unnecessary.
Worked example
Place a transparent logo on white before exporting it as JPEG.
Limitations and responsible use
- JPEG cannot preserve transparency.
- Text, diagrams, and flat-color graphics may look worse or become larger than the original PNG.
- Canvas export may discard embedded metadata and color-profile information.
Frequently asked questions
Why must I choose a background?
Every transparent or semi-transparent pixel needs an opaque color because JPEG has no alpha channel.
Can I convert the JPG back to the original PNG?
You can create a PNG later, but lost transparency and compression detail cannot be recovered.
