Which portals require PDFs under 500KB?

500KB is one of the strictest document size limits in Indian government portals. Banking recruitment portals (IBPS, SBI), Passport Seva, and most central ministries enforce this. A standard scanned certificate from a scanner/phone is typically 2–5MB — this tool gets it under 500KB.

How to compress your PDF to 500KB (3 steps)

  1. Upload your scanned certificate, marksheet, or document using Choose PDF or drag and drop. Works with scanned PDFs from any scanner or phone camera app.

  2. Target is pre-set to 500KB. Click Compress PDF to 500KB. The tool runs a binary search across quality and resolution settings to reach 500KB.

  3. Download the result. If 500KB is unreachable (e.g., many high-resolution scanned pages), the tool returns the smallest possible size and shows you how close it got.

Frequently asked questions

My scanned certificate is 4MB — can I get it to 500KB?

Usually yes. A single-page scanned certificate at 300 DPI is typically 2–5MB. This tool compresses it by re-rendering at a lower resolution and JPEG quality. A single-page document almost always reaches 500KB. For multi-page documents (10+ pages), 500KB may be very tight — try splitting the PDF first using our Split PDF tool.

Why does the IBPS portal reject my PDF even after compressing?

IBPS portals check both file size and sometimes file integrity. Make sure: (1) the file is under 500KB, (2) it's a valid PDF (not renamed), and (3) it opens correctly in a PDF viewer before uploading. If the portal still rejects it, try splitting the document and uploading individual pages.

Will quality suffer at 500KB?

For a single-page certificate, 500KB allows reasonable JPEG quality (60–75%) — text remains readable and official seals/stamps are visible. For multi-page documents compressed to 500KB, quality will be lower. Always preview the download before submitting to a portal.
