At ResizeHub (https://resizehub.vercel.app/), user privacy and data sovereignty are fundamental architectural principles. ResizeHub operates on an uncompromising 100% Client-Side Processing architecture.
All image resizing, cropping, compression, conversion, and PDF operations are executed entirely within your local web browser using the HTML5 Canvas API, Typed Arrays, and Web Workers. No photos, signatures, exam cards, or documents are ever uploaded, transmitted, or stored on any external server or cloud database. Your media remains strictly on your personal device at all times.
ResizeHub is supported by privacy-conscious third-party advertising networks, including Adsterra. These advertising providers may use cookies, web beacons, or non-personally identifiable identifiers to serve contextual advertisements and measure ad performance. These third-party vendors have their own independent privacy policies, and no user images or personal documents are ever accessible to or shared with advertising networks.
We use lightweight web telemetry (such as Vercel Analytics) to track aggregate, non-personally identifiable metrics including page views, referrer URLs, and tool usage frequencies to optimize site performance.
By using ResizeHub, you acknowledge and consent to client-side local memory processing and applicable third-party advertising cookies. You may disable cookies through your browser settings at any time without impacting image processing capabilities.

ResizeHub is provided on an 'AS IS' and 'AS AVAILABLE' basis without warranties of any kind, whether express, statutory, or implied. While we strive for absolute accuracy in dimension calculations and compression algorithms, ResizeHub and its creators shall not be liable for any submission rejections, exam portal failures, or data loss resulting from the use of this utility suite.
ResizeHub was built by web engineers committed to delivering ultra-fast, accessible, and privacy-respecting media tools without subscription paywalls, intrusive registrations, or cloud data risks.
Every day, millions of applicants, students, designers, and job seekers struggle with rigid government exam photo portals (such as 20KB-50KB limits, exact 2x2 inch dimensions, and clean ink signatures). Most existing tools require uploading sensitive personal documents to unknown remote servers or paywalling basic exports.
ResizeHub solves this through zero-upload client-side engineering. By taking full advantage of modern HTML5 Canvas APIs, typed binary arrays, Web Workers, and jsPDF, all operations happen directly on your device with lightning speed, zero bandwidth waste, and absolute confidentiality.
Have questions, feedback, or a feature request for a specific government portal or exam specification? We would love to hear from you!
