Compress a PDF for online forms
Exam, job, passport and scholarship portals in India often cap uploads at 100 KB, 200 KB or 1 MB, while a phone scan of a certificate can easily be 5 MB. This PDF compressor shrinks the file right on your phone or computer. Choose a quality level, or simply type the size limit and let the tool find the best quality that fits. Your documents are never uploaded.
How to compress a PDF
- Choose your PDF.
- Pick Quality level, or Target size and enter the limit in KB.
- Optional: tick Black & white for text documents.
- Tap Compress PDF, check the result and download it.
How it works
Each page is redrawn at a sensible resolution and saved as an optimised JPEG image inside a new PDF. Lower resolution and quality mean smaller files; the levels below are tuned for documents you need to read on screen.
| Level | Resolution | Best for |
|---|---|---|
| High quality | 150 DPI | Printing, photos |
| Recommended | 120 DPI | Certificates, scans |
| Smallest | 96 DPI | Strict upload limits |
| Extreme | 72 DPI | Very strict limits — check readability |
Example
A 3-page scanned caste certificate is 4.8 MB, but the portal allows only 500 KB. With Target size = 500 KB the tool tries High quality (too big), then Recommended — about 420 KB — and stops there, keeping the sharpest version that fits. Zoom into the result to confirm small text is readable before uploading.
