Why Kagazo Client-Side Processing is Safer Than Traditional Cloud Converters
Most generic PDF converters and photo resizers upload your sensitive documents (such as Aadhaar cards, caste certificates, college marksheets, and signatures) to overseas cloud servers where files are stored temporarily or indefinitely. Kagazo fundamentally rejects this architecture.
- Zero Server Uploads: Files remain on your device. Zero bytes leave your browser RAM.
- Instant Zero-Latency Execution: No waiting for remote server upload or download queues.
- Complete Data Sovereignty: Complies with IT Act and Digital Personal Data Protection (DPDP) principles.
- Unrestricted Free Usage: No daily file caps, no paywalls, and no forced watermark logos.
- •Cloud Storage Risk: Private marksheet and identity documents uploaded to remote third-party servers.
- •Severe Usage Limits: Often restricts users to 2 free files per day before displaying subscription paywalls.
- •Forced Brand Watermarks: Injects unwanted logo stamps on your official government documents.
- •Slow Upload/Download Queues: Dependent on server load and internet bandwidth for large PDF files.

Frequently Asked Questions
Everything you need to know about processing exam documents, privacy, and free tools.
Q:Why do government job portals (UPSC, SSC, TNPSC, RRB) reject uploaded photos and signatures?
Recruitment portals use strict automated server validation scripts. Rejections almost always happen due to three factors: (1) File size violations—e.g., uploading a 52KB photo when the portal strictly caps uploads at 50KB; (2) Incorrect pixel dimensions or aspect ratios—e.g., uploading 200×200px when the portal expects 350×350px or 3.5×4.5cm; and (3) Missing mandatory metadata—such as candidate name and Date of Photo (DOP) printed on the lower strip within 10 days of the notification. Kagazo auto-pads undersized scans and strictly enforces KB caps to guarantee 100% portal acceptance.
Q:How does Kagazo compress certificate PDFs to strictly 200KB or 100KB without blurring roll numbers?
Unlike generic online compressors that indiscriminately reduce raster image resolution until text becomes illegible, Kagazo utilizes advanced client-side WebAssembly rendering. It isolates background scan grain, optimizes embedded fonts, cleans Xerox noise, and applies targeted quantization. This ensures critical educational details—such as University roll numbers, subject marks, and Controller of Examinations signatures—remain crisp and legible even under 200KB and 100KB caps.
Q:Is my personal data, marksheet, or Aadhaar number uploaded or saved on Kagazo servers?
No. Kagazo operates on a strict zero-upload, zero-persistence privacy architecture. All compression, image resizing, format conversions, and PDF decryptions execute locally inside your web browser’s volatile computer RAM memory using HTML5 Canvas, WebAssembly, and FileReader APIs. Your files are never transmitted to external cloud servers or stored in databases. When you close the tab, all file memory is instantly purged.
Q:Can I add candidate name and Date of Photo (DOP) on UPSC, SSC, and TNPSC exam photos?
Yes. Our specialized recruitment resizers (including UPSC Photo Resizer, SSC Photo Resizer, and TNPSC Photo Resizer) include dedicated DOP text banner engines. You can type the applicant’s name and select the exact photo capture date, which is dynamically rendered onto a compliant white bottom strip conforming to official notification guidelines.
Q:How do cyber cafe and CSC operators print 8 passport photos on a single 4×6 inch sheet?
Using our Cyber Cafe Passport Photo Sheet Maker, operators upload a single portrait photo and select the standard 4×6 inch (10×15 cm) photo paper layout. The tool instantly generates a ready-to-print gang sheet with 8 perfectly aligned 3.5×4.5cm passport photos, complete with thin cutting borders and proper margins for Epson, Canon, and HP photo inkjet printers.
Q:Can I merge multiple semester marksheets into a single PDF under 1MB or 2MB?
Yes. The Multi-Marksheet to Single PDF Merger allows students and graduates to upload all semester grade cards, degree certificates, and provisional diplomas. It re-orders pages, compresses high-resolution camera scans, and produces a single unified PDF strictly under 1MB or 2MB, which is mandatory for UPSC ORA, State PSC, and corporate job portals.
Q:Are the developer tools (JSON Formatter, Code Minifiers, Base64) safe for proprietary source code?
100% safe. Because every developer utility on Kagazo runs purely client-side via JavaScript in your local browser sandbox, zero lines of source code, API keys, JSON payloads, or database SQL queries ever leave your computer. You can safely format internal production JSON without risking proprietary data leaks.
Q:Does Kagazo work on Android and iOS mobile phones without installing any app?
Yes! All 135+ tools are fully responsive progressive web utilities that run seamlessly in Chrome, Safari, Firefox, and Edge on Android phones, iPhones, tablets, and desktop computers. You can take a photo directly with your phone camera, resize it to 20KB–50KB, and download the finished file in seconds without downloading third-party APKs or apps.
