Frequently Asked Questions

Q.Why do scholarship portals and colleges require PDFs under 100KB?

Portals like the National Scholarship Portal (NSP), state welfare departments, university admissions, and e-court systems mandate strict file sizes below 100KB. This ensures fast document previews for evaluating officers, prevents upload timeouts, and keeps portal database storage efficient.

Q.Will my marksheet grades and signatures stay readable under 100KB?

Yes! SizeSnap uses intelligent client-side canvas vectorization. It compresses high-frequency color backgrounds while sharpening dark ink text and university seals, ensuring full legibility during official document verification (DV).

Q.Can I compress multi-page PDF documents to 100KB?

Yes. SizeSnap dynamically distributes compression across pages to stay below 100KB. If your document has more than 3 pages of high-resolution color scans, we recommend converting color scans to grayscale or compressing each page individually.

Q.Is my Aadhaar card or income certificate uploaded to any server?

Never. SizeSnap processes documents 100% locally inside your web browser. Your confidential Aadhaar numbers, bank account statements, and educational certificates never leave your phone or computer.

Q.What should I do if a 5MB scanned certificate will not reach 100KB?

If your scan is exceptionally large (e.g., 5MB–10MB at 600 DPI), run the output through the compressor once more, or use our "Image to PDF" tool to convert your certificate at 150 DPI Grayscale. 150 DPI is the official sweet spot for 100KB certificate uploads.
