Complete Guide: How to Compress PDF Documents to Under 100KB
When uploading supporting documents (such as caste certificates, class 10/12 mark sheets, degree diplomas, domicile certificates, or income certificates) to Indian public sector recruitment portals, state scholarship platforms, or court e-filing systems, candidates frequently encounter this error:
Standard office desktop scanners often generate PDF files of 2MB to 8MB for a single scanned page. Shrinking that down to strictly under 100KB without rendering the text illegible or failing digital signature verification is a major challenge.
