Frequently Asked Questions

How does image compression work?

The tool re-encodes images using the HTML5 Canvas API at your selected quality level. Lower quality settings remove less noticeable image detail, significantly reducing file size while maintaining acceptable visual quality.

Will compression change my image dimensions?

No. Compression only reduces the file size. The image width and height remain exactly the same unless you resize the image separately.

Which image format compresses the most?

WebP generally produces the smallest file sizes while maintaining excellent visual quality. JPEG also compresses photographs efficiently, while PNG is often preferred for graphics and images with transparency.

Are my images uploaded to a server?

No. Every image is compressed locally inside your browser. Your files never leave your device.

Is there a file size limit?

The tool does not enforce a strict file size limit. However, very large images may take longer to process depending on your browser and available device memory.

Is this image compressor free?

Yes. You can compress images online for free without creating an account or installing software.
