What this tool does
- Resizes images to useful web dimensions.
- Converts to WebP, JPEG or PNG using your browser.
- Lets you balance visual quality against page weight.
- Removes metadata because a fresh output file is created from image pixels.
Practical image guidance
- Use WebP for most photographs and website graphics.
- A 1600 px maximum width is usually enough for a full-width website image.
- Keep PNG for transparency or graphics that need lossless output.
- Animated images export as a single static frame.
