Is this image compressor private?

Yes. Image compression happens locally in your browser, so your files are not uploaded to our servers.

Which image formats can I compress?

You can compress common image formats including JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC.

Will image quality change after compression?

Compression settings affect the final balance between file size and visual quality. In most cases you can reduce image size significantly while keeping the image clear enough for web, email, and everyday sharing.

Can I compress multiple images at once?

Yes. You can add multiple images, compress them together, and download the results one by one or as a ZIP archive.
