About FABX Labs

We make the exact file an Indian form asks for — the photo at 200 × 230 pixels, the signature between 10 and 20 KB, the certificate PDF between 50 and 300 KB — and we make it on your own phone, so the file is never uploaded.

Why this exists

Millions of people fill exam, scholarship, tax and government forms every year, and the upload step fails for reasons nobody explains: a file 1 KB over the limit, a PNG renamed to .jpg, a signature photographed on grey paper. Generic compressors and chatbots guess. A portal does not — it checks the bytes. So every FABX tool has one job and hits a number.

What we build, and what we won't

• We build tools whose output must be a byte-exact file: exact pixels, a KB window with a floor and a ceiling, a real JPEG or PDF header, a printed name-and-date strip.
• We don't build calculators, résumé builders or anything a chatbot already does well.
• We never generate handwriting, signatures or thumb impressions — tools only clean, trim, resize and stack what you made yourself.

How sizes are checked

Every preset is compiled from the conducting body's own notice where one is published, and from exam-prep consensus where it isn't. Pages say which is which, and the size specs table marks each row. Your own notification always wins — every tool lets you type its numbers.

How your files are handled

On fabxlabs.com, files are processed in your browser and never sent to us. We use Google Analytics to count visits and which tools are used, never file contents or names (privacy policy). The separate AI connector does process files on our servers so an assistant can use them, and deletes them within an hour.

Who we are

FABX Labs is built by Aman, founder and vibe coder. Write to [email protected] — we read everything, and a tool you ask for may be the next one we ship.
