Guidelines Overview

Every government recruitment and certification portal enforces unique formatting constraints. This system prevents poor upload file quality, preserves catalog layout consistency, and minimizes storage database overheads. Uploads failing to match these specs are rejected silently by automated validators.

Sizing & DPI Compliance

Scanning files at the wrong dimensions or resolution leads to pixelated distortion or giant file sizes. Our sizers are preconfigured to output images mapped precisely to target centimeter proportions while automatically embedding necessary DPI header metadata directly into your JPEG files.

Secure Browser-Side Processing

Protecting your identity files is our ultimate goal. ToolXHub executes 100% of formatting computations directly inside your client-side browser memory. None of your passport photos, written signatures, or personal records are ever uploaded to cloud servers, securing your identity from server hacks and data logging.

Privacy Assurance: Your files never leave your device. All calculations execute locally inside your web browser using HTML5 Canvas.

The UIDAI online portal allows document updates (proof of identity and proof of address) up to 2MB per file, in JPEG, PNG, or PDF format.
Does ToolXHub upload my Aadhaar card to any server?▼
