Why Choose ResizeKB?

Most online converters require uploading your sensitive documents—like passports, national identification cards, and resumes—to remote servers. This poses severe data privacy and security risks. ResizeKB performs 100% browser-side processing. Your documents are parsed, resized, and encoded locally on your computer or mobile phone. Your data never leaves your device.

Frequently Asked Questions

Yes. ResizeKB runs entirely client-side. We use your browser's processing engine (Canvas API and JavaScript memory) to resize images and PDFs. Because there is no server upload, your sensitive personal documents (like Aadhaar cards, passport photos, and certificates) remain entirely private on your device.

ResizeKB loads lightweight open-source engines (PDF.js and PDF-Lib) directly in your browser. When you select a PDF, the browser renders its pages onto an invisible canvas, compresses the canvas drawing into an optimized JPEG structure, and packs those JPEGs back into a brand new PDF file, all within local memory.

Many government, job application, and admissions portals require files to be under specific file sizes (e.g., photos under 50KB or PDFs under 200KB). We automate the trail-and-error process by running a binary search on the quality parameters until the file meets the exact limit.

Absolutely. ResizeKB is designed mobile-first. It is extremely fast, lightweight, and works on Safari (iOS), Chrome (Android & iOS), and standard mobile browsers without needing any app installations.
