How to compress an image to 100 KB

- Target is preset to 100 KB. Leave it, or change the number.
- Compress & download. Download your image at ~100 KB.
Why 100 KB is a good default for the web
Unlike 20 KB or 50 KB, a 100 KB target is usually a choice rather than a restriction imposed on you. It is the point where a photograph still looks genuinely good and the page still loads quickly on a phone connection.
Page speed is a ranking signal and, more importantly, a reason visitors stay. A page carrying ten images at 100 KB transfers a megabyte; the same page at 1 MB each transfers ten. On a slow connection that is the difference between a page that appears and a page that is abandoned.
What fits in 100 KB
| Content | Workable size | Result |
|---|---|---|
| Blog inline image | 800×600 | Sharp |
| Product photo | 1000×1000 | Good detail on a plain background |
| Full-width banner | 1600×600 | Fine — wide images compress well |
| Detailed landscape | 1920×1080 | Visibly soft in foliage and texture |
Approximate — flat backgrounds stretch the budget considerably further than busy detail.
Serve the size you actually display
The most common cause of a slow page is not weak compression but images far larger than the space they occupy. A 3000 px photo displayed in a 600 px column still costs the visitor every one of those pixels.
Resize to roughly the display size first — or twice it, if you want it to stay sharp on high-density phone screens — and only then compress. Doing it in that order usually gets you under 100 KB with quality to spare.
