How does the image compressor work?

Our compressor uses browser-native Canvas API and the browser-image-compression library to reduce file size by adjusting quality and optionally resizing. Your image never leaves your device.

What image formats are supported?

We support JPG/JPEG, PNG, and WebP formats. GIF files can be uploaded but will be converted to the original format during compression.

Will compression reduce image quality?

At higher quality settings (80—100), the difference is barely noticeable. Lower settings (below 60) will show visible quality loss but achieve much smaller file sizes.

Is there a file size limit?

You can compress images up to 50MB. For very large files, processing may take a few seconds.

Are my images stored anywhere?

No. All compression happens entirely in your browser. Your images are never uploaded to any server.

What image formats does the compressor support?

The tool supports JPG (JPEG), PNG, and WebP formats. You can compress any of these and download the result in the same format.

How much can I reduce an image's file size?

Depending on the original image and quality setting, you can typically reduce file size by 40% to 90%. A 5 MB photo can often be compressed to under 500 KB with minimal visible quality loss.

Is my image uploaded to a server?

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

Can I compress multiple images at once?

Yes. You can process multiple images in the same session by uploading them one after another.

Why should I compress images for my website?

Large images are one of the biggest causes of slow page load times. Google's Core Web Vitals penalize pages with oversized images. Compressing images can dramatically improve your site's performance and SEO ranking.
