Compress an image to 20KB
Get an image under 20KB — the size range where avatars, icons and email signature graphics belong. Small enough that repeating it across thousands of page views costs almost nothing.

How it works
- 1

- 2
The target is already set to 20KB.
- 3
Click Compress and download the result.
Why use this converter
- Cheap to repeat
An avatar loads on every comment and every listing; 20KB versus 200KB compounds across a page.
- Right for flat graphics
Logos, icons and signatures hold up at this size in a way photographs do not.
- Target already set
The field arrives at 20KB — upload and download.
- Free, no watermark
No account and nothing added to the image.
When to use it
- Profile avatars: Loaded dozens of times per page on anything with comments or listings.
- Email signature graphics: Mail clients are unforgiving about weight, and many block large images by default.
- Icons and logo marks: Flat artwork that stays crisp well under this budget.
- Favicons and app tiles: Small by definition; there is no reason for them to be large.
Why small repeated images matter more than big ones
A single hero image at 300KB costs one download. An avatar at 30KB shown beside forty comments costs 1.2MB. The small image is the more expensive one, and it is the one nobody thinks to check.
This is why avatars, icons and list thumbnails deserve a much tighter budget than the images people actually notice. The saving multiplies by however many times the asset appears.
Resize before you compress at this size
Getting to 20KB by compression alone means destroying quality, if the image is still 1000 pixels wide. An avatar displayed at 48 pixels does not need more than about 96 pixels of source for a sharp result on a high-density screen.
Cut the dimensions to roughly what is displayed, then compress. The file will land well under 20KB without looking degraded, because you removed pixels nobody was seeing rather than approximating the ones they were.
Frequently asked questions
Can a photograph work at 20KB?
Rarely at any real size. This budget suits flat graphics — logos, icons, signatures. A photograph at 20KB works only if it is also physically small, like a thumbnail.
Why does my image look rough at this size?
Almost always because its dimensions are far larger than needed. Reduce the pixel size first, then compress — the result is much better than compression alone.
Is this small enough for an email signature?
Yes, comfortably. Mail clients are strict about total message weight, and 20KB leaves room for the rest of the message.
What formats can I upload?
JPG, JPEG and PNG.
