Processing stays local. JPG, PNG, and WebP work best.
How to use this page
- Upload the image you plan to email.

- Use JPG or WebP for photos and PNG for screenshots that need crisp text.
Common questions
Can I compress images without uploading them?
Yes. The tool runs in your browser session, so the image file does not need a server upload or an account.
Will this change my original file?
Download creates a new output file and keeps the original image unchanged.
What should I try if the result is still too large?
Use a smaller pixel size first, remove unused edges with crop when possible, and then run compression again on the prepared copy.
