Resize Image to 100KB Online

The 100 KB target is where resizing and compression meet: on most photos you can hold the original dimensions and still get there, but the result is noticeably cleaner if you first bring the width down to something reasonable for the screen it will be shown on. Both options live in the same tool below, preset to 100 KB.

How to use it

  1. 1Add your image — it is read locally, so nothing is transmitted anywhere.
  2. 2The tool opens on the target-size mode with 100 KB filled in. Switch to the dimensions tab first if a form also specifies a pixel width and height.
  3. 3Run it, then read the measured output size and dimensions in the result panel.
  4. 4Download the file, or adjust the target and run it again until the balance of size and sharpness suits you.

Frequently asked questions

Will the file be exactly 100 KB?

No — 100 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 100 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 100 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.

Does resizing change the pixel dimensions?

In target-size mode the tool keeps your original dimensions and lowers the encoding quality first, because that is usually enough. If you also need specific pixel dimensions, set them on the dimensions tab before running the tool — smaller dimensions make the target far easier to reach.
