Will compressing to 100 KB make my marksheet unreadable?

Usually not. The tool reduces JPG quality first and scales the page down only if that is not enough. Grayscale helps most for text documents because it removes colour data the page does not need.

Which exams allow a 100 KB photo or signature?

The list on this page comes from our exam database. Open an exam page for its full photo and signature spec and the official source it came from.

100 KB target

Fit your image under 100 KB.

At 100 KB the photo rules loosen and the document rules take over. A few exams allow a photo up to 100 KB, and the NTA exams and the UPSC registration allow a signature that large, five times what the bank forms accept.

It is also a common cap for scanned certificates and marksheets, and that is where most people get stuck. A phone photo of an A4 page is usually 2 to 4 MB. The compressor below is set to 100 KB and tries lower quality before it touches the resolution, so small print stays as sharp as the limit allows.

Target file size

Grayscale — recommended for scanned marksheets & certificates (much smaller, text stays sharp)

Tips for this size

For a printed certificate or marksheet, turn on grayscale. The text reads the same and the file often drops by half, which leaves more room for resolution.
Straighten and crop the page before compressing. The Document Scanner tool fixes a skewed phone shot and cuts away the table or bedsheet around it.
If the portal wants a PDF under 100 KB rather than a JPG, build the PDF with the size cap set. Converting an already compressed JPG to PDF afterwards can push it back over.
Zoom in on the result before you upload. If the roll number or seal is blurred, the verifying officer can reject it later even though the portal accepted the file.
