Why compress images?
Large images take up more storage space and take longer to load. Compression can reduce file size and make images easier to upload, send and store.
When compressing JPG and WebP images, you can choose a balance between image quality and file size. Lower quality settings will generally produce smaller files.
The image is processed directly in your browser, so the file does not need to be uploaded to a server.

Frequently asked questions
Which formats can I compress?
Inputs include JPG, PNG, WebP, AVIF, HEIC, HEIF, BMP and TIFF. Outputs are JPG, PNG or WebP. With the original-format option, AVIF becomes WebP; HEIC, HEIF, BMP and TIFF become JPG.
Why does lowering quality not reduce PNG size?
The quality setting applies to JPG and WebP. PNG encoding does not use it; reduce dimensions or choose another format for a smaller file.
Is a smaller result guaranteed?
No. Re-encoding an already optimized image can increase its size. Compare the results and adjust format, quality or dimensions.
