How to use the Compress Image to 100KB
- Press Choose images, drop them on the box or paste with Ctrl+V; you can add up to 50 JPG, PNG or WebP files at once.
- Under Goal, keep Best balance and set the Quality slider, or choose Under a size and pick a limit such as 100 KB.
- Optionally change Save as or Longest side, then press Compare on any image to check the before and after with a sliding divider.
- Press Download for one image, or Download all to get every compressed image in a single ZIP.
Good to know
- Under 100 KB, a photo around 1200 pixels on its longest side still looks crisp on phones. Set Longest side to 1080 or 1600 px for the best balance.
- For a website, 100 KB per image keeps pages quick on mobile data. Save as WebP for the smallest files that still look sharp.
- Logos and screenshots saved as PNG often fit under 100 KB with fewer colours and no visible change.
- Quality 75 usually looks the same as the original at a fraction of the size. Below about 70, photos turn a little softer, and below 55 visibly so.
- For photos, WebP or JPG is far smaller than PNG. Keep PNG for logos, screenshots and graphics with see-through backgrounds.
- If a photo cannot reach your limit at low quality, the tool also makes it smaller in pixels. If it still will not fit, it tells you.
- Hidden photo details such as location, camera and date are removed, which is good for privacy before you post or send a picture.
- Need an exact shape too, like 1080 × 1350 for Instagram? Resize first with the Image Resizer, then compress here.
