How to resize and compress PDF for SSC, UPSC, and government exams?

Frequently Asked Questions (FAQ)

How does Vexiro reduce PDF size without making text blurry?

Unlike ordinary compressors that blindly downscale resolution into pixelated mush, Vexiro uses an intelligent background paper noise cleaner. In scanned documents, off-white paper texture takes up 70% of the byte budget. By flattening this noise into clean white, we can preserve high DPI resolution (up to 150 DPI) and razor-sharp text while drastically reducing the file size.

Can I compress multi-page scanned PDF documents?

Yes! Vexiro supports multi-page PDFs. Our engine calculates an optimal per-page byte budget (e.g. allocating ~35 KB per page for a 4-page 150 KB target) and applies adaptive multi-pass optimization so each page remains clear and readable.

Is it safe to compress confidential bank statements and Aadhaar PDFs?

Yes, 100% private and secure. All processing takes place locally inside your device's web browser RAM using JavaScript and WebAssembly. Your files are never uploaded to any remote cloud server, ensuring complete confidential privacy.

How can I compress PDF files on my smartphone (Android / iPhone)?

Simply open https://tool.vexiro.in/pdf-compressor.html in Google Chrome or Safari on your phone. The responsive mobile interface allows you to pick any PDF from your phone storage, choose your desired size, and download it directly without installing third-party apps.

Why did my previous compressor fail on government portals?

Most exam portals have strict binary thresholds (e.g. maximum 100.0 KB). Many online compressors produce 101 KB or 104 KB, causing instant rejection. Vexiro guarantees that your output is strictly within your chosen limit and provides byte-exact matching.
