Resizer · free, in your browser

Compress an image to 100 KB or less

Application forms, job sites and government portals often ask for a photo under a set size. Type the limit and Resizer searches for the highest quality that still fits, for one picture or a whole batch.

Compress to 100 KB

How to do it

1. Drop the picture (or several) on the page.
2. Resize by is set to Maximum file size (pictures), with 100 KB. Change the number if your limit is different.
3. Leave Width and height at 0 to keep the pixel size, or type a size if the form also asks for one.
4. Press Resize all, then check the size after on each row and download.

The limit works for JPEG, WebP and AVIF, whose quality can be lowered step by step. PNG has no quality setting, so a PNG can only get smaller by getting fewer pixels: set a width and height as well, or choose JPEG.

Your files stay on this device: Resizer runs in your browser, with no upload, no account and no watermark.

Questions

How does it reach the size?

It encodes the picture at different qualities and keeps the best one under your limit, in seven steps between low quality and the quality you chose.

What if it still does not fit?

Give it fewer pixels too: type a smaller width or height. A smaller picture needs fewer bytes at the same quality.

Can I compress to 50 KB or 20 KB?

Yes. Type any number of KB in Maximum file size (KB). Very small limits need a smaller width and height to stay readable.

Is the photo uploaded?

No. The compression runs in your browser and the photo never leaves your device.
