No. The compressor works entirely inside your own browser, so your images never leave your device. That makes it safe for personal photos, ID documents, work files and anything else you would not want stored on a third-party server.

JPG, JPEG, PNG, WebP and GIF are all supported. You can also choose to convert your compressed image to JPEG, WebP or PNG before downloading. GIF files are treated as still images, so animation is not preserved.

Most photos become 40% to 80% smaller, depending on the original file and the compression strength you choose. Images that are already heavily optimized may only shrink a little, while large camera photos often shrink dramatically.

A few images are already extremely well optimized. If that happens, raise the compression strength, switch the output format to WebP, or set a Maximum Width to downscale the picture — resizing is usually the fastest way to cut file size.

There is no hard limit, but very large files above about 60 MB may slow down or strain your browser. For the smoothest experience, keep individual images under 20 MB.

Yes. Use the Max Width field to downscale large photos before compression. Combining resizing with compression usually gives the smallest possible result.

Compression always involves a trade-off, but you stay in control. Start with a moderate strength and raise it gradually until you reach the smallest file that still looks good to you. For most web and email use, a strong setting is visually indistinguishable.

Yes. It is completely free, requires no account, adds no watermark and has no daily limit. You can compress as many images as you like — simply repeat the steps for each file.
