About FormForge
FormForge is a free, browser-based PDF form builder — made by a working developer who wanted a tool that creates fillable PDFs without uploading your documents to anyone's server.
Why FormForge Exists
Every existing way to make a fillable PDF form asked for something I wasn't willing to give. The desktop apps wanted a subscription for a task that takes two minutes. The free web tools wanted me to upload the document first — contracts, HR paperwork, intake forms, the exact kind of file you'd never paste into a random website. And the "simple" editors buried the one feature I needed under menus built for something else entirely.
I'm a developer. I knew the whole job — reading a PDF, drawing form fields onto it, and writing those fields back into the file — could run entirely inside a browser tab. No upload. No account. No server that quietly keeps a copy. So I built FormForge to prove it: import a PDF, drag the fields you need onto the page, export a real fillable form that works in Adobe Reader, Preview, and every major browser. The document never leaves your machine, and you can confirm that yourself by watching the network tab while you use it.
It's free because it costs almost nothing to run — the work happens on your device, not mine. That's the whole pitch: an honest tool that does one job well and respects the files you feed it.
Who Builds It
I'm Aleksandar “Aleks” Jovanovic — a full-stack developer and indie hacker based in Germany. I run The CodeCave GmbH, a custom software agency, and in between client work I build my own products in public. My background spans Flutter mobile development, web development, and a stack of small SaaS tools — so I've shipped enough real software to know that a good tool is one that gets out of your way.
FormForge came out of that same build-in-public habit: notice a task that's more annoying than it should be, then build the version I actually want to use.

How FormForge Works
FormForge renders your PDF with PDF.js and writes form fields back into it using pdf-lib. Both run in JavaScript, inside your browser — so every step, from opening the file to exporting the finished form, happens client-side. These are the principles that keep it that way:
Privacy First
Your PDF never leaves your browser. Zero uploads, zero server processing, zero third-party access.
Honest & Free
No subscription, no upsell, no limits, no signup. Free because client-side software costs almost nothing to run.
Built for Speed
Import, drag fields onto the page, export. Three steps, no waiting on uploads, no learning curve.
