Compress Image Online

Frequently asked questions

Which image formats are supported?

We support JPG/JPEG, PNG, WebP, HEIC, and AVIF. Notably, HEIC is the default format for iPhone and iPad photos — you can compress them directly without converting first. AVIF is a next-generation format offering excellent compression ratios.

What are the file size and count limits?

Up to 20MB per image and 30 images per batch. There is no daily usage limit — you can use the tool as many times as you want for free.

Will compression visibly reduce image quality?

It depends on the preset. The "Balanced" preset (40-60%) is designed so the human eye cannot detect a difference — suitable for most web and social media uses. "Smallest" will show some quality loss, which is acceptable when file size is the priority. "High quality" preserves virtually all visible detail.

Are my images safe?

Yes. All transfers use HTTPS encryption. Images are stored temporarily on our private servers and automatically deleted after 15 minutes. We never view, analyse, or share your images with any third party.

Is it really free? Are there any limits?

Completely free. No usage limits, no account required, no Pro tier or paywall. The site is sustained by advertising — you see a banner, we pay for servers, the tools stay free.

Does it work on mobile?

Yes. The interface is mobile-first and works well on both iPhone and Android. You can select images from your photo library, take a new photo, or drag and drop images into the upload area.
