How to compress an image to a specific size

  1. Choose an image

    Select the JPG, PNG or WebP image you need to make smaller.

  2. Pick a target size

    Choose 50 KB, 100 KB, 200 KB, 500 KB or 1 MB, or enter your own limit in KB.

  3. Compress and download

    The best quality that fits under your limit is found automatically. Check the size and download.

When do you need an image under a certain size?

Many forms limit the size of uploaded images: job and university applications, government and visa portals, exam registrations, profile pictures, online marketplaces and email attachments. If yours says something like "maximum 100 KB", choose that as your target and your image will fit.

The tool tries a high quality first and only lowers it as far as needed, so you keep as much detail as the limit allows. The image's width and height never change.

If the image is still too big

  • Use the Image Resizer to make the image smaller in pixels, which is the most effective way to reach small targets.
  • Use the Image Cropper to cut away parts of the image you don't need.
  • Use the PNG to JPG to turn a large PNG into a much smaller JPG.
  • Use the Image Compressor to compress by choosing a quality level yourself instead of a size.

Frequently asked questions

Will my image be exactly 100 KB?

No. The target is a maximum: the image is compressed to the highest quality that is at or below it, so the result is usually a little smaller, for example 96 KB for a 100 KB target. It is never larger than the target when the target is reached.

How big is a KB here?

1 KB is 1,000 bytes and 1 MB is 1,000,000 bytes, so a 100 KB target means at most 100,000 bytes. Upload forms usually count sizes the same way, but if a form counts 1 KB as 1,024 bytes, a file under our target is still under theirs.

Why couldn't my image reach the target size?

Very large photos can't always get that small at their current dimensions without looking noticeably worse, so the tool stops at a sensible minimum quality instead of ruining the image. Reduce the image's width and height, or crop it, and try again.

Why doesn't this work well for PNG images?

PNG is lossless, so there's no quality setting to lower. The image can only be re-saved, which rarely makes it much smaller. To reach a small target, resize the image or convert it to JPG or WebP.

What happens if my image is already under the target?

It isn't recompressed. You get your original image back, unchanged, so there's no quality loss.

Is it free, and are my images uploaded?

It's free with no sign-up, and your images are never uploaded: compression happens in your browser, on your device.

Does it change the image dimensions?

No. Only the file size changes. The width and height stay the same, and metadata such as camera details and location is removed.
