Government Portal Rejects Your PDF Upload
A PDF rejected by a government portal with errors like "invalid format," "file too large," "unsupported PDF version," or "digital signature required" has a specific technical mismatch with the portal's requirements. Here's how to fix each rejection type.
A PDF that is rejected by a government filing portal, tax submission site, court e-filing system, or regulatory portal is failing one or more of the portal's technical requirements. Unlike consumer apps, government portals often have very specific PDF requirements: size limits, version restrictions, security settings, or digital signature mandates. The portal's error message — if specific enough — tells you exactly what to fix.
File Too Large: Compress Before Upload
The most common rejection reason. Most portals have file size limits: 5 MB, 10 MB, or 25 MB are typical. Check the portal's requirements page (usually in the help section or FAQ). Use FixMyPDF Compress to reduce file size. For scanned documents, the biggest gains come from reducing scan DPI — 150 DPI is sufficient for legibility on screen and for most government portals; the default 300+ DPI scan produces 4-9x the file size with no benefit for portal submission. If the document must remain high resolution, split it across multiple uploads if the portal permits.
Wrong PDF Version
Some older government portals reject PDF 1.7, PDF 2.0, or later — they were built against PDF 1.4 or 1.5 and have not been updated. Conversely, some portals require at least PDF 1.4 and reject older versions. The PDF version is set at export time. In Acrobat Pro: File → Save As → PDF → Options → "Compatibility" dropdown. Re-save as PDF 1.4 (Acrobat 5 and later) — this is the most widely compatible version and accepted by virtually all portals. If the portal specifically requires a newer version, that will be stated in the requirements.
Encrypted or Password-Protected PDFs
Government portals almost universally reject password-protected PDFs because they cannot process or store encrypted files in their document management systems. If your PDF has an open password (required to view) or a permissions password (restricting printing or copying), remove it before uploading. Use FixMyPDF Unlock if you know the password. After removing encryption, verify the PDF opens without any password prompt before re-uploading.
Digital Signature Required
Some portals (notably Indian income tax portal, Ministry of Corporate Affairs, court e-filing) require PDFs to have a valid digital signature from a government-accredited CA (Certifying Authority). This is different from a handwritten signature image — it requires a DSC (Digital Signature Certificate) issued by a licensed CA (eMudhra, Sify, NSDL, etc.). The signing must be done with their proprietary signing software or a DSC USB token. If this is required, no standard PDF tool can satisfy it — you need to obtain a DSC and use the portal's approved signing workflow.
Rejected as "Invalid PDF" Despite Opening Normally
Some portals use stricter PDF parsers than desktop viewers. A PDF that opens fine in Acrobat may be structurally non-conformant in ways that strict parsers reject: duplicate object IDs, malformed cross-reference tables, or non-standard stream compression. Fix: run the PDF through a normalizer. In Acrobat Pro: File → Save As → PDF (overwrite) — Acrobat rewrites the cross-reference table and normalizes the structure. Alternatively, use Ghostscript: gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=out.pdf in.pdf — this re-generates a structurally clean PDF that passes strict validation.
