How to use the Image Compressor
Image Compressor reduces the file size of a JPEG, PNG, or WebP image for faster sharing and uploading. Three quality choices let you balance visual detail against a smaller download while comparing the original and compressed versions.
Choose an image
Upload a JPEG, PNG, or WebP file up to 25 MB.
Set the quality balance
Choose Best quality, Balanced, or Smallest file based on how much compression you want.
Compress and compare
Create the new image, inspect its preview and file size, then download it.
What to know
- The exact reduction depends on the original format and how efficiently it was already saved.
- Repeated lossy compression can soften detail, so work from the best original available.
Questions people ask

Is my image uploaded to Tool Alien?
