Is this image compressor free?

Yes. It is completely free with no sign-up, no watermark and no file-size or resolution cap. You can compress as many images as you like and download them at full resolution.

Are my images uploaded to a server?

No. Compression happens entirely in your browser on an HTML canvas. Your images are read from your device and never leave it.

How do I compress an image without losing quality?

Keep the quality slider high (around 80–90%) and use JPG or WebP. You will usually cut the file size by half or more with no visible difference; lower the slider further only if you need a smaller file.

Which format gives the smallest file?

WebP usually produces the smallest files at the same quality, followed by JPG. PNG stays lossless and is best for graphics and transparency rather than photos.

Can I compress many images at once?

Yes. Add multiple images, set one quality level, and use Download all to save every compressed image one after another.
