About Avinash Verma

Avinash started ImageConverterTool after repeatedly hitting the same wall himself: needing a photo under a form’s exact KB limit, converting a screenshot, or resizing a signature for an exam portal — and not wanting to install software or upload personal files to someone else’s server. That frustration shaped the site’s core principle: the routine image tools run in your browser where supported, so your files are not uploaded to our servers for routine operations.

Since then he has built and maintained 50+ of these tools — exact-KB compression, format conversion across JPG, PNG, WebP, AVIF and HEIC, resizing for passport and signature requirements, background removal, PDF workflows, and metadata cleanup — and tests them against the constraints people actually face, from SSC, UPSC and IBPS exam-photo caps to KYC and visa-portal rules.

He also writes the site’s guides and blog, focusing on the decisions that trip people up: which format to choose, how to hit a strict file-size limit without wrecking quality, how image weight affects mobile page speed and Core Web Vitals, and how to share images without leaking location or device metadata. The aim throughout is honest, practical guidance — including saying plainly when a tool has a real limitation rather than overselling it.

Part of that work is public. The compression approach behind the exact-KB tools — a binary search on encoding quality that converges on a target file size instead of guessing with a slider — is published as open source in the compress-to-size repository on his GitHub profile, where anyone can read, test, or reuse it. ImageConverterTool is also not his first developer-tools property: he builds and runs jsonviewertool.com, a separate collection of browser-based JSON utilities, and maintaining two live tool sites means edge cases found on one — an odd file, a browser quirk, a portal that rejects a technically valid upload — routinely improve the other.

Every major tool page here carries a “Last tested” note describing what was actually verified: selecting input, processing, previewing, and downloading, in current Chrome, Safari, and Firefox on both desktop and mobile, plus how the tool behaves when it is given an unsupported or oversized file. The broader testing and review approach is documented on the methodology page. If a tool behaves differently on your device, or a portal rejects a file it produced, the fastest route to a fix is the contact page — include the page URL, your browser and device, and the file type, and it gets looked at against the same checklist used to test the tool in the first place.
