Why Not Just Use TinyPNG or Squoosh?

Most online compressors upload your files to their servers. Your personal photos, screenshots, and work files travel through someone else's infrastructure. This tool is different.

Your Files Stay Yours

Nothing gets uploaded. Period. Your browser does all the heavy lifting — we never see your images.

No Waiting Around

Skip the upload progress bar. Compression starts the instant you click — even on slow Wi-Fi.

No Limits, No Tricks

No daily caps, no "upgrade to unlock" popups, no forced signups. Just drag, compress, download.

JPEG vs WebP: Which Should You Choose?

JPEG is the universal standard — every device and app supports it. Choose JPEG when compatibility matters most.

WebP produces 25-35% smaller files at the same quality. It's supported in all modern browsers (Chrome, Firefox, Safari 16+, Edge). Choose WebP for web images, social media, and email attachments.

PNG is lossless, so the quality slider has no effect. Use PNG for screenshots, logos, and graphics where sharp edges matter.

Frequently Asked Questions

Are my images uploaded to a server?

No. This tool runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device — no data is sent to any server.

Is there a file size limit?

There's no hard limit, but very large images (50MB+) may be slow depending on your device. For best performance, we recommend images under 50MB each.

Does compression remove EXIF metadata?

Yes. Browser-based Canvas compression strips EXIF data (camera info, GPS location, etc.). If you need to preserve metadata, use the MediaOptim desktop app which offers EXIF preservation.

Why is my PNG file not getting smaller?

PNG is a lossless format — browsers don't apply quality-based compression to it. For smaller files, try converting to JPEG or WebP using the format selector.

Can I compress images on my phone?

Yes! This tool works on mobile browsers. For a dedicated mobile experience with more features, check out the MediaOptim mobile app.
