Preparing documents for online applications is often a stressful task. When applying on the official Union Public Service Commission (UPSC) Civil Services portal, candidates and professionals frequently hit file size limits. The portal requires all uploaded Caste certificates, EWS documents, and age proof certificates to be in PDF format and sized strictly under 200KB.

Why the UPSC IAS Portal Rejects Large PDFs

The Union Public Service Commission (UPSC) Civil Services portal processes thousands of uploads daily. To protect server speeds and ensure compatibility for users in remote areas with slow internet connections, they enforce a hard size cap of 200KB. Trying to upload a raw scan directly from your phone will trigger an upload failure.

How to Optimize Your Documents for UPSC IAS

UPSC has a narrow size window of 100KB to 200KB. PDFs smaller than 100KB will be rejected as well, so do not over-compress.

Using PDF Pro's vector-preservation tool allows you to compress your scanned files to the exact required size without making the text blurry or illegible. Rejections during manual document verification (DV) are often due to pixelated scans. PDF Pro ensures that signatures, stamps, and certificate serial numbers remain perfectly readable.
