Common questions
Can I resize 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.
