Government portals like UPSC, SSC, IBPS, and state PSC recruitment boards routinely reject document
uploads that exceed their file size limits — typically 100KB, 200KB, or 500KB.
Marksheets, degree certificates, caste certificates, and identity proofs are the most common files
that need to be compressed before upload. This tool compresses any PDF to your chosen target size,
entirely inside your browser with no file upload to any server.
The compression technique used here renders each page of the PDF as a high-quality JPEG image and
then assembles a new, smaller PDF from those images. This is very effective for scanned
documents (marksheets, certificates, ID proofs), which make up the bulk of government
exam uploads. The text remains clearly legible even after compression.
For SSC CGL, CHSL, MTS document uploads, the typical size limit is 100KB per
document. For UPSC Civil Services, most certificates need to be under
200KB or 300KB. For IBPS/SBI bank exams, documents are usually
accepted up to 500KB. For Aadhaar address update document proof,
the limit is typically 2MB.
If your compressed PDF is still slightly above the target size, try with a more aggressive target
(e.g. set 80KB instead of 100KB) to ensure it fits within the portal's limit. You can also try
scanning the original document at a lower DPI (150 DPI is usually sufficient for readable text).
This tool works seamlessly on Android and iPhone browsers — no app required. Since
all processing is done in the browser, there is no server cost, no sign-up, and no limit on
how many files you compress. The tool is free forever.
