Compress an image in 3 steps

  1. Choose your JPG, PNG or WebP images.
  2. Pick a target: 20, 50, 100, 200, 500 KB, or type your own number.
  3. Press "Compress" and download the smaller file. If you added several images, they come in one ZIP.

How it helps

  • Lands under the size you need

    You set the KB limit, and the tool looks for the best quality that still fits under it. You don’t have to guess with a slider.

  • ID photos aren’t uploaded

    Compression runs in your browser, so a passport photo or a scanned document stays on your phone or computer.

  • Many images at once

    Compress one image or a few dozen in one go, as often as you like. It’s free, there’s no account to create, and no watermark is added.

  • Straight from your phone

    Take the photo, open this page and compress it. You don’t need to install an app on iPhone or Android.

Frequently asked questions

How do I get a photo under 100 KB (or 50 KB) for an application form?

Drop the photo here, pick the limit the form asks for (or type your own) and press "Compress". You get the highest-quality JPG that fits under that size. Some institutions also ask for minimum pixel dimensions or turn down blurry, over-compressed photos, so check their official guide as well.

What is the difference between file size and dimensions?

File size is how much space the image takes up, in KB or MB. Dimensions are its width and height in pixels. This tool lowers the file size and keeps the dimensions when it can. It only scales the image down if there’s no other way to reach the target. To change the pixel size itself, use the Resize Image tool.

Will the quality drop?

A little. A smaller file always holds less detail. The tool picks the highest quality that still fits your target, so at sensible sizes the difference is hard to spot. Very small targets like 20 KB will look softer.

What happens to transparent PNGs?

The result is always a JPG, and JPG doesn’t support transparency. Transparent areas turn into a white background. If you need to keep the transparency, this isn’t the right tool.

Does it work on my phone?

Yes. Open this page in your phone’s browser, tap "Choose files" and pick your photos. JPG, PNG and WebP work. iPhone’s HEIC format isn’t supported yet, so set the camera to "Most Compatible" if you want new photos saved as JPG.

Are my images uploaded?

No. The compression happens in your browser on your own device. Your photos don’t reach our servers, and no copy is kept after you close the page.
