Frequently Asked Questions
Why do recruitment portals limit PDF certificate sizes to 200 KB or 300 KB?
Portals like UPSC and state public service commissions receive hundreds of thousands of document uploads simultaneously. Capping PDFs to 200 KB or 300 KB ensures fast server processing and efficient database storage.
Does this tool upload my sensitive certificates to external servers?
No. ApplyReady processes and recompresses PDF documents 100% inside your local web browser. Your marks, personal details, and certificates never touch any external server.
How does the tool ensure text on the compressed PDF remains readable?
The tool uses selective JPEG stream quantization. It calculates the minimum compression required to satisfy your exact KB target without discarding high-frequency text contours, ensuring dates, roll numbers, and grades stay legible.
Can I convert photos of certificates directly to a compressed PDF?
Yes. You can upload photo scans (JPG or PNG) directly. The compressor automatically compiles them into an A4 PDF guaranteed to be under your chosen target file size.
What is the typical PDF size limit for UPSC Civil Services online application?
UPSC typically requires scanned document PDFs (such as photo identity proof and age relaxation certificates) to be between 20 KB and 300 KB.
What should I do if my PDF file is still too large?
If your original document was scanned at ultra-high 600 DPI, choose a lower target like 200 KB or 150 KB. The tool will automatically scale pixel dimensions to comfortably meet the limit.
