Convert PNG to JPG
Going from PNG to JPG is the usual way to make a heavy screenshot or export small enough to send, upload or attach.

Decide what happens to transparency
Transparent pixels must be flattened onto something. White is the safe default for documents and light interfaces; black suits dark UI screenshots. Set the background colour before you export.
Screenshots are a special case
Screenshots contain sharp text edges, and JPG's lossy compression smears them slightly. If the text has to stay razor sharp, keep the PNG or export WebP instead.
FAQ
Frequently asked questions
- How much smaller will the JPG be?
- For photographic PNGs, typically a large reduction. For flat-colour graphics the difference is smaller, and PNG can even win.
- What happens to the transparent background?
- It is filled with the background colour you choose, because JPG cannot store transparency.
- Is the conversion reversible?
- You can convert back to PNG, but the detail discarded by JPG encoding is gone for good.
- Are my images uploaded to a server?
- No. Every step — decoding, cropping, resizing and encoding — runs in your browser using the Canvas API. The image file never leaves your device, so nothing is stored or transmitted by us.
