Free Image Compressor 🐾

Shrink and convert images right in your browser. Your photos are never uploaded — no account, no watermark, no subscription.

Most “compress image online” sites upload your photos to their server and nudge you toward a paid plan. QR Puppy doesn't: this runs entirely on your device with the browser's own image engine, so your pictures never leave your computer and there's no limit but your own machine.

Why compress on your own device?

  • Private. Your photos never touch a server — nobody can keep, scan, or leak them.
  • Free with no limit. No “5 images a day”, no watermark, no upgrade prompt.
  • Fast. No upload/download round-trip; it's instant.
  • Convert too. Turn a big PNG into a tiny WebP or JPEG in one click.

QR Puppy started with QR codes — but a lot of things people pay monthly for are just work your own device can do. So we give those away too.
