Why compress images to 100 KB?
Many portals cap document uploads at 100 KB, and large images slow down websites and emails. A modern phone photo can be several megabytes, so compressing it to around 100 KB saves space and time with little visible difference.
Compressing scanned documents
For scanned marksheets, certificates and ID cards, keep the width around 1200 to 1600 pixels so text stays readable, then let the tool find the right compression. If text looks soft, raise the target slightly or crop out empty margins first.
Frequently asked questions
How do I reduce an image to 100KB without losing quality?
Set a reasonable width, such as 1200 px, and a 100 KB target. The tool picks the highest quality that fits, so the result looks very close to the original.
Can I compress a scanned document to 100KB?
Yes. Upload the scan as a JPG or PNG and set the target to 100 KB. For a scanned PDF use our Compress PDF tool instead.
What is the output format?
JPG, which gives the smallest size for photos and scans.
