About SignResize.in
Empowering millions of students and job applicants with instant, private, and mathematically precise signature resizing tools.
Our Mission: Simplifying Sarkari Application Prep
Every year, millions of Indian applicants apply for competitive recruitment exams such as SSC (CGL, CHSL, GD, MTS), UPSC, Banking (IBPS PO & Clerk), Railway (RRB NTPC, ALP, Group D), and identity documents like PAN Cards (NSDL/UTIITSL).
Unfortunately, thousands of applications face rejection or server upload errors due to strict, unforgiving requirements: "Signature must be between 10 KB to 20 KB", "Width must be exactly 140 pixels and height 60 pixels", or "Resolution must be 200 DPI on clean white paper".
SignResize.in was founded with a singular purpose: to provide a completely free, lightning-fast, and 100% private web utility that eliminates technical friction for aspirants in every corner of India.
Why SignResize is Different
100% Client-Side Privacy
Unlike traditional image converters that upload your personal signature to remote cloud databases, our engine processes every single byte inside your browser using HTML5 Canvas & WebAssembly. Your signature never leaves your phone or laptop.
Dual-Boundary Compression
Standard compressors only let you reduce size. Our dual-boundary algorithm ensures your output file lands precisely between both minimum and maximum limits (e.g., strictly 10.0 KB to 20.0 KB) so portals never reject your upload.
Centimeter to Pixel Precision
Official notifications often specify sizes in Centimeters (e.g., 4.0 cm × 2.0 cm) or Inches. Our built-in unit converter automatically calculates exact pixel dimensions at 200 DPI standard scanning density.
Digital Drawing Canvas
No paper or scanner handy? Sign directly on your mobile screen with your finger or stylus, crop to dimensions, and download an official-compliant JPEG in seconds.
Engineering & Document Verification Team
Ammy Kamble • Lead Technical Architect
Systems Engineer • Client-Side Canvas & WebAssembly Performance Lead
Lead software engineer and creator of SignResize. With a focus on client-side security and browser-native graphics, Ammy designed the dual-boundary binary search JPEG compressor and Clean White Paper 3.0 algorithms. He actively audits examination notification bulletins (SSC, UPSC, NSDL, IBPS, RRB) to keep dimension, DPI, and kilobyte upload boundaries strictly up to date.
All image processing runs in your device's browser memory via HTML5 Canvas. We maintain zero cloud upload servers for user images.
Outputs are rigorously tested against live validator constraints of SSC OTR, UPSC Online (upsconline.nic.in), NSDL Protean, and RRB.
Dual-boundary binary search ensures files strictly respect both floor limits (≥ 10 KB, ≥ 20 KB) and ceiling caps (≤ 20 KB, ≤ 50 KB).
Our Commitment to Quality and Accessibility
SignResize.in is designed to work smoothly on entry-level Android smartphones with low 3G/4G connectivity, as well as desktop workstations in cyber cafes and schools. We require no app installs, no registration, and no software licenses.
