Maximum file size: 50 MBHow to Compress a PDF in 3 Easy Steps
Most Indian government job portals — SSC, UPSC, IBPS, SBI, Railway RRB, state PSCs — set strict file size limits on PDF uploads. If your scanned certificate, signature, or filled form is over the limit, the portal rejects it. Here is the simple way to fix that.
Upload Your PDF
Click the upload box above or drag and drop your PDF file. Anything up to 50 MB works.
Pick a Target Size
Choose the size limit from the official job notification — 100KB, 200KB, 500KB or 1MB.
Download & Upload
Click Compress, then download your smaller PDF and upload it to the job portal.
Why You Need to Compress PDFs for Government Job Applications
If you have ever applied for an SSC, UPSC, IBPS PO, SBI Clerk, Railway RRB or state government exam, you have seen messages like "File size should not exceed 200KB" or "Upload PDF below 500KB". These limits exist because government servers handle lakhs of applications during peak hours and need to keep storage manageable.
The problem: a PDF made from a phone scan, especially of a coloured certificate or marksheet, is usually 2–10 MB. That is 10 to 50 times bigger than what most forms accept. Trying to upload it gives an error and your application stays incomplete.
Common file size limits on Indian job portals
| Exam / Portal | Photo | Signature | Documents (PDF) |
|---|---|---|---|
| SSC (CGL, CHSL, MTS) | 20–50 KB | 10–20 KB | 50–200 KB |
| UPSC (CSE, NDA, CDS) | 20–300 KB | 20–300 KB | up to 300 KB |
| IBPS (PO, Clerk, RRB) | 20–50 KB | 10–20 KB | 20–500 KB |
| SBI Recruitment | 20–50 KB | 10–20 KB | 20–500 KB |
| Railway RRB | 20–50 KB | 10–20 KB | 50–500 KB |
| State PSCs (typical) | 20–100 KB | 10–50 KB | 100 KB–1 MB |
Always confirm the exact limits from the official notification — these are common ranges and may change.

Complete User Guide
1. Before you start
Open the official notification PDF for the exam you are applying to. Find the section that says "Specifications for documents to be uploaded" or similar. Note down the maximum file size in KB. This is the number you need to hit.
2. Prepare your PDF
If you have a scanned image (JPG, PNG) instead of a PDF, first convert it to PDF using your phone's scanner app (CamScanner, Adobe Scan, or Google Drive Scan). Make sure the document is fully visible, not blurry, and not rotated.
3. Compress with this tool
- Click the orange upload box at the top of this page.
- Select your PDF from your device.
- Once it loads, you'll see the file name and current size.
- Pick the target size that matches the form requirement.
- Press the Compress PDF button.
- Wait a few seconds — for a 5 MB file, compression takes about 3–8 seconds.
- Click Download Compressed PDF to save the smaller file.
4. Upload to the job portal
Go back to the application form, click the upload button next to the document field, and select the compressed PDF from your Downloads folder. The portal should accept it without an error.
5. If compression doesn't reach your target
Some PDFs — especially those with many high-resolution colour images — cannot be compressed below a certain size without becoming unreadable. If you can't get below 100KB:
- Rescan the document in black and white instead of colour.
- Lower the scan resolution to 150 DPI (most phones default to 300 DPI).
- Crop tightly around the document so there's no white border.
- Combine all pages into a single PDF only if the form asks for it.

Light compression (file size reduced by 30–60%) keeps text and images sharp. Heavy compression — for example, squeezing an image-heavy 5 MB PDF down to 100 KB — may slightly reduce image clarity. To keep quality, use the largest size the form will accept (so 500 KB is better than 100 KB if both are allowed).
Yes. This tool works on Android and iPhone browsers (Chrome, Safari, Firefox). Open this page on your phone, tap the upload box, select your PDF from Files or Gallery, and follow the same steps as on a computer.
This happens when the PDF has many high-resolution colour images. Try these:
- Rescan the original document in black and white
- Reduce scan resolution to 150 DPI
- Crop unwanted borders before scanning
- Use the "100 KB Extreme" option in this tool
No. You'll need to remove the password first using a PDF unlock tool, then compress. This is a safety feature — we don't want to bypass passwords on documents that aren't yours.
You can upload PDFs up to 50 MB. If your file is bigger than that, split it into smaller PDFs first, compress each, and merge them back if needed.
You need internet to load this page once. After that, compression happens locally in your browser — so even if your connection drops, you can still compress the PDF.
