How to use it
Add your image
Drag it here or choose it from your device. Photos and scans both work.
Keep the 100 KB limit
100 KB is preselected. If your form needs exact pixels or centimeters, set them first.
Resize and download
Press Resize images and download the result. You can change the limit and run it again.
Photos and documents at 100 KB
100 KB leaves room for a clear photo of about 400 by 500 pixels, or for a readable scan of one document page. It is twice the room of a 50 KB limit, so faces and printed text stay noticeably sharper.
Text edges are the first thing to suffer from compression. Check the result at 100 percent zoom, and if a document is hard to read, try the 200 KB limit.
Tips for a 100 KB image
- For scanned documents, scan at 150 to 200 DPI. Higher resolutions only make the file larger.
- Choose JPG for photos and scans. Use PNG only for logos and flat graphics.
- If the text in a scanned document looks blurry, raise the limit to 200 KB instead of lowering the quality further.
- Crop away empty margins before resizing.
