FAQ
PNG to JPG questions, answered
Why convert PNG to JPG?
Smaller file size for photographs and screenshots, especially for email or web upload. A 5 MB PNG can drop to 400 KB as JPG at 90% quality with no visible difference.
What happens to transparent regions?
JPG doesn't support an alpha channel, so any transparent pixels get flattened against white before the encode. If you need a different background colour, do the flatten step in your image editor first.
What quality should I pick?
85 to 92% is the sweet spot: visually indistinguishable from the original for almost all photos and screenshots, with the biggest size savings. Below 70% you start seeing artefacts; above 95% the file balloons with no visible gain.
Is anything uploaded?
No. Everything runs in your browser via the Canvas API. DevTools → Network will confirm. No request carries your image off your device.
Can I batch-convert and download as a zip?
Yes. Drop multiple PNGs, hit "Download all": we wrap them in a single .zip via JSZip. All client-side.
