How do I compress an image online for free?

Upload your image, choose a compression level, and click Compress Image. The optimized file downloads automatically — no account or payment required.

Will compressing my image reduce quality?

A little. Lower compression = larger file size. Higher compression = smaller file size. Most images can be reduced by 50–70% with minimal visible quality loss.

What image formats can I compress?

JPG/JPEG, PNG, WebP, and GIF are supported — all processed directly in your browser using high-quality APIs.

Is this image compressor secure and private?

Yes. Nothing is uploaded or stored. Compression is 100% local to your device.

Can I compress multiple images at once?

Yes! Upload multiple images, compress them all together, and download as a ZIP file or individually.

Are there any file size limits?

No hard limits. Your device's memory is the only constraint.

How much can I reduce file size?

Typically 50–80% depending on image content and selected quality.
