About compress images online
Image compression reduces the number of bytes needed to store or transfer a picture. It helps pages load faster, keeps email attachments manageable and makes uploads fit within service limits without changing the pixel dimensions.
Choose Low for gentle compression, Recommended for a practical balance, or Strong for the smallest result. JPEG, WebP and AVIF use progressively lower quality settings. PNG is optimized losslessly, so its reduction may be smaller and depends heavily on the artwork.
When should I use it?
- Shrink a photo before attaching it to email or a support ticket.
- Optimize website images without learning a long list of encoder settings.
- Fit an image under an upload limit while keeping its width and height.

Frequently asked questions
Which compression level should I choose?
Recommended is the best starting point. Use Low for valuable photographs and Strong when file size matters most.
Does compression resize the image?
No. This tool preserves pixel dimensions; use Resize Image when you also need fewer pixels.
Why is my PNG only slightly smaller?
PNG compression is lossless, and an already optimized graphic may have little redundant data left to remove.
