Sarvesh Kumar is the lead developer and image optimization specialist behind ResizeKB.tech, a platform that has helped thousands of users compress and resize images for government applications, job portals, and document submissions across India.

With over 5 years of experience in web development and image processing technologies, Sarvesh specializes in client-side image compression algorithms that maintain quality while achieving exact file size requirements. His expertise stems from extensive research into government document photo specifications, having analyzed requirements for over 30 different Indian government bodies including NSDL, RRB, SSC, UPSC, and passport authorities.

Sarvesh's work at ResizeKB focuses on solving real-world problems that millions of Indians face when applying for government services. He has personally tested dozens of image compression tools and documented their limitations, which inspired him to build ResizeKB as a truly free, privacy-focused alternative that processes images entirely in the browser without uploading data to any server.

Through his technical blog articles, Sarvesh shares in-depth knowledge about image formats, compression standards, and practical tutorials for meeting strict government photo requirements. His writing combines technical accuracy with accessibility, making complex image optimization concepts understandable for non-technical users.
