Which portals require PDFs under 100KB?
100KB is applied to single-page document uploads like caste certificates, disability certificates, and domicile certificates on IBPS, Railway RRB, and some state PSC recruitment portals. These portals assume documents are a single page — a multi-page PDF will almost never reach 100KB without splitting first.
| Portal / Platform | PDF Limit | Document Type |
|---|---|---|
| IBPS Portal | ≤ 100KB | Caste / disability certificate |
| Railway RRB | ≤ 100KB | Category certificate (1 page) |
| State PSC portals | ≤ 100–200KB | Supporting documents |
| UPPSC / BPSC | ≤ 100KB | Scanned certificates |
| Some municipal portals | ≤ 100KB | Identity documents |

Tips for compressing to 100KB
100KB is achievable for single-page PDFs. For multi-page documents, split to one page first using our Split PDF tool, then compress. The tool resamples images to very low DPI (72–96) to hit 100KB — text remains legible but very small fonts may be slightly soft. Ensure your scan is in portrait orientation and well-lit for the best readable output.
How to compress a PDF to 100KB (3 steps)
If your PDF has multiple pages, first use our Split PDF tool to extract just the certificate page. Then drop the single-page PDF into the tool above.
The target is pre-set to 100KB. Click Compress PDF to 100KB. The tool auto-adjusts quality and image DPI to hit the target.
Download and upload to IBPS, Railway RRB, or your state portal. If still rejected, try reducing at a lower quality — or contact the portal's helpdesk, as some portals are inconsistent.
Frequently asked questions
Can I compress a scanned caste certificate to 100KB?
Yes — a single-page scanned caste certificate (which is usually 1–3MB as a PDF) compresses well below 100KB. The text and official seal remain visible and readable. If the original scan is very dark or poorly lit, compress at a slightly higher quality to preserve legibility.
IBPS says file must be below 100KB — my PDF is 800KB after compression?
This usually means your PDF has multiple pages. IBPS expects single-page certificates. Split your PDF to just the required page using our Split PDF tool, then compress — a single page compresses to 100KB easily.
Is 100KB quality good enough for government portals?
Yes. Government recruitment portals verify document content visually during the scrutiny stage. A 100KB PDF of a single certificate page is completely acceptable — the name, date, and official stamp remain clearly readable at standard screen and print sizes.
