Smaller File Better Quality
This free online image compressor allows you to reduce the file size of your photos and images quickly and privately. It solves common problems like email attachments being too large, website images slowing down your page load speed, or social media platforms rejecting uploads due to size limits. Whether you're a blogger optimizing web content, a developer compressing assets for an app, or just someone needing to send a batch of photos via email, this tool is perfect for the job. All compression happens directly in your web browser using advanced JavaScript—your images are never uploaded to any server, guaranteeing 100% privacy and security. There are no watermarks, no usage limits, and no registration required. Support includes JPG, PNG, and WebP formats.

Frequently asked questions

Which formats can I compress?

The compressor works with JPG, PNG, and WebP images, which covers most photos and screenshots.

Will compression visibly reduce quality?

Lower quality settings produce smaller files with more compression artifacts. Adjust the slider and preview the result to find the balance you want.

Is there a file size limit?

Practical limits depend on your device memory because processing is local. Very large images work best when the browser has enough free memory.
