Compress Image to 500KB Online

500 KB is a generous target that suits large photographs, detailed screenshots and images that will be viewed at full resolution. Most photographs reach it with a barely perceptible quality change, which makes it a good default when a site simply asks you to 'keep images small' rather than naming a hard number. The engine below starts at 500 KB.

When you need this

  • Publishing large photos to a site that asks for images under half a megabyte
  • Reducing camera files before archiving or emailing them
  • Keeping detailed screenshots readable while cutting the file size

How to use it

  1. 1Drop your JPG, PNG or WEBP image into the upload area, or tap it to pick a file from your device.
  2. 2The target size is already set to 500 KB. Change it in the target field if the form you're filling in asks for something different.
  3. 3Press the button and let the encoder step the quality down until the measured file is at or under the target.
  4. 4Check the Original, Result and Saved figures, then press Download to save the file.

Frequently asked questions

Will the file be exactly 500 KB?

No — 500 KB is a target, not a guarantee. The tool re-encodes your image repeatedly at lower quality until the measured output is at or below 500 KB, then stops. The number you see in the result panel is the real byte count of the file you download, so you can always confirm it before uploading anywhere.

What happens if my image can't reach the target?

If a very large or very detailed photo can't reach 500 KB at a reasonable quality, you'll get the smallest file the encoder could produce along with a note explaining it. Reducing the pixel dimensions first is the fastest fix: halving width and height removes about three quarters of the pixels and usually drops the file far below the target.

Is my image uploaded to a server?

No. Everything runs in your browser using the Canvas API. The file never leaves your device, there is no account to create, and nothing is stored after you close the tab.

Is there a watermark or a limit on how many images I can do?

There is no watermark and no daily limit. Because processing is local, the only real constraint is your device's memory, which the tool checks before it starts.
