Frequently Asked Questions About Image Compression
Answers about compressing PNG, JPEG, WebP and AVIF images online
CompressItAll reduces file size by removing unneeded metadata and re-encoding the image data. Lossless mode keeps every pixel identical to the original. Lossy mode trades a small amount of detail for a smaller file, and you can set the quality yourself. It works on PNG, JPEG, WebP and AVIF files.
Yes. CompressItAll is free to use and needs no registration. You can compress up to 5 images at a time and run as many batches as you like.
It depends on the image and the format. Screenshots and graphics with flat colours shrink the most, and photos that were already compressed shrink the least. Compare the original and compressed sizes in the results table, and use the before and after view to check quality. One test PNG of 211 KB came out at 121 KB, about 43% smaller.
Yes. Compression runs on our servers, so your files are uploaded over an encrypted HTTPS connection, processed, and then deleted automatically. Do not upload images you are not comfortable sending to a web service.
Yes. Upload up to 5 PNG, JPEG, WebP or AVIF files at once, mix formats if you like, and compress them together. When they finish you can download each file or all of them as one ZIP archive.
Lossless compression shrinks the file without changing any pixel, so the original image can always be recovered. Lossy compression discards detail the eye is unlikely to notice, which gives smaller files at the cost of some quality. Choose lossless for logos, screenshots and anything you will edit again, and lossy for photos.
Yes. PNG transparency is preserved, and so is transparency in WebP and AVIF. JPEG does not support transparency at all, so a transparent image saved as JPEG gets a solid background.
The upload area accepts up to 5 files at a time. If a large photo fails or takes too long, resize it in an image editor first and then upload the smaller copy.
