Image Sign Resizer & Compressor — Free Online Image Resize Tool for Government Forms 2026

Welcome to Image Sign Resizer & Compressor, India’s most trusted free online tool for resizing and compressing passport Image and signatures to meet the exact file size and dimension requirements of government job applications, online forms, and official portals. Whether you are applying for India Post GDS (Gramin Dak Sevak), SSC, UPSC, Railway, Bank PO, or any central or state government recruitment, this tool ensures your Image and signature meet the precise specifications — instantly, for free, and without uploading your files to any server.

What is Image Sign Resizer & Compressor?

Image Sign Resizer & Compressor is a fully browser-based image resizing and compression tool designed specifically for Indian government job applicants. It allows you to upload any Image or signature image and resize it to exact pixel dimensions while also compressing it to a target file size in kilobytes (KB). The tool supports multiple output formats including JPG, JPEG, WebP, PNG, GIF, BMP, TIFF, JFIF, and AVIF — giving you full control over the final image quality and compatibility.

Why Do You Need to Resize & Compress Your Image and Signature?

Almost every government online application form in India requires candidates to upload a passport-sized photo and handwritten signature in specific formats. For example, India Post GDS 2026 recruitment requires the photo to be in JPG/JPEG format, sized between 200×250 pixels, with a maximum file size of 50KB and a 4:5 aspect ratio. The signature must follow a 5:2 aspect ratio and stay within 20KB. Similarly, SSC CGL, IBPS, RRB, and other exams impose strict file size limits ranging from 10KB to 100KB.

If your image exceeds these limits, the portal will reject your upload — potentially causing your application to fail. Manually resizing images with desktop software is time-consuming and confusing for most users. That is why Photo Sign Resizer & Compressor was built — to make the entire process instant, accurate, and accessible to everyone with just a smartphone or computer.
