Image compression reduces the data stored in an image file. JPG and WebP can often become substantially smaller by changing encoding quality, while PNG uses lossless compression and varies by image content. Compression does not intentionally change dimensions; use Image Resizer when you need fewer pixels.
How to compress images

Image Compressor FAQ
Are my images uploaded?
No. Files are read and exported only through a local browser processing flow.
Can I compress multiple images?
Yes. The queue processes images conservatively to avoid excessive browser memory use.
Why did my PNG barely shrink?
PNG is lossless and many PNG files are already optimized. The tool will not offer a larger file as a compressed result.
