Is UltraImageCompression free to use?

Accepted Answer

Yes, completely free. No account, no subscription, no watermarks on output. Compress unlimited images at zero cost.

Question 2

Does compressing an image reduce quality?

Accepted Answer

Our binary-search algorithm finds the highest possible quality that meets your target file size. For 200KB+, quality loss is imperceptible. Smaller targets may show slight compression but look great at normal viewing sizes.

Are my images uploaded to your servers?

Accepted Answer

No. All compression happens in your browser using JavaScript and the HTML5 Canvas API. Your images never leave your device.

Question 4

What image formats are supported?

Accepted Answer

JPG/JPEG, PNG, and WebP are supported for input. Output is delivered as optimized JPEG. Use our Image Converter for format conversion.

Question 5

Can I compress multiple images at once?

Accepted Answer

Yes — upload up to 20 images simultaneously and download all compressed files with one click.
