AethrosForms is a 100% client-side PDF suite — no uploads, no accounts, no cloud. Fill AcroForms, merge, split, reorder pages, and password-encrypt PDFs entirely in your browser using WebAssembly. Your files never touch a server. Built by ÆTHROS™ as sovereign infrastructure for privacy-conscious individuals and teams.
Hey Product Hunt 👋
I'm Sig, founder of AETHROS Holdings. I built AethrosForms because every free PDF tool I tried either uploaded my files to a server or wanted an account before letting me do anything.
AethrosForms runs 100% in the browser using WebAssembly — fill forms, merge, split, organize, and password-encrypt PDFs without a single byte leaving your device. No server. No account. No ads.
The encryption is real: qpdf compiled to WASM, AES-256, password-enforced and confirmed working in Adobe Acrobat.
Would love feedback on:
→ Which tool do you use most?
→ What's missing that would make you switch from your current PDF tool?
Try it at aethrosforms.com — free forever.
Stirling PDF is impressive. 76K GitHub stars, $2M raised, 50+ tools. Respect.
But it requires Docker, a server, and technical deployment…
That’s why we built AethrosForms.
Open your browser. Use it. Done.
→ No Docker → No server → No account → No install → Files never leave your device → AES-256 encryption, built in → Free forever
Stirling PDF owns self-hosted enterprise. We own instant, zero-friction, sovereign PDF for everyone else.
