How to compress an image to 100 KB
- Drop a photo, scan or screenshot into the box above, or choose a file.
- The maximum is already 100 KB. Change it if your form allows a different size.
- Check the result: the size is always under the limit, and it tells you if the dimensions changed.
- Select Download to save the JPG.
Photos of documents under 100 KB
For ID cards, bills and certificates, what matters is that the text stays readable. A few things help it survive compression:
- Fill the frame with the document. Crop off the table and background, so the pixels go on the text. Use the crop tool first if needed.
- Shoot in good, even light. Shadows and grain take space and make small text harder to read.
- One document per image. Two pages in one photo means each gets half the detail.
Quality you can expect
A 100 KB JPG usually holds about 0.5 to 1 megapixel of photo at good quality. That's sharper than most phone screens show a form photo, and enough for an A4 document photo where normal-size text is still legible. If you need more detail than that, see whether the form accepts 200 KB with the200 KB compressor.
Common uses
- Uploading ID and address proof. Document upload pages for bank accounts, SIM cards and rental agreements often cap each image at 100 KB. A phone photo of the document comes out readable and under the limit.
- Admission and scholarship forms. University and scholarship portals frequently accept photos and certificates up to 100 KB. Compress each scan or photo once and upload without trial and error.
- Images for a lightweight web page. Keeping each image under 100 KB is a common rule of thumb for fast pages on mobile data. Enter 100 and the photo keeps as much detail as that budget allows.
