Compress images to under 200 KB

200 KB is a sweet spot for web pages, product listings and larger form uploads. Your images stay sharp and load fast, and they never leave your device.

Your images are processed on this device and never uploaded. We don't see, store or log your files.

Common sizes

How it works

  1. Tap Choose files, or Take photo on a phone, and add JPG, PNG or WebP images.
  2. Tap Compress images. Each image is saved as a JPG under 200 KB.
  3. Download the images one by one or as a ZIP, or tap Share.

Why compress here

Your photos never leave your phone or computer, and camera location data (EXIF) is not copied into the new files. It is free, with no watermark and no account, and you can compress many images at once.

What fits in 200 KB

About 1600 × 1000 pixels fit in 200 KB at good quality, enough for a full-width photo on most websites. A 3 MB phone photo usually keeps around half its width; screenshots and simple graphics often keep their full size.

Web pages and listings

Images under 200 KB help pages load quickly on mobile data. For a gallery of many images, 100 KB each is often enough; for a single large hero image, 200 KB keeps it crisp on big screens.

Frequently asked questions

Is 200 KB small enough for a website?

For most photos, yes. Page speed tools usually flag images well above that. If you show many images on one page, try Compress image to 100 KB instead.

Can I keep transparency?

No. Results are JPG, which has no transparency, so transparent areas become white. To keep transparency use Resize image, which keeps PNG.

Is 1 KB 1,000 or 1,024 bytes?

Sites count it both ways. We aim for 1,000 bytes per KB, so a 50 KB file here is at most 50,000 bytes and also passes a form that counts 1,024 (51,200 bytes).

Are my images uploaded?

No. Everything happens in your browser on your own device.
