Why I Built This
I got frustrated with tools like SmallPDF and
ILovePDF uploading my sensitive documents to
their servers. I wanted something that works
entirely in the browser.
So I built Wrklyst — a growing collection
of free utility tools that process files locally
using WebAssembly. Your files never leave
your device.
What's Inside
- PDF tools (merge, compress, convert, sign)
- Image tools (convert, compress, resize)
- Writing tools (word counter, grammar checker)
- Developer tools (JSON, regex, base64)
- Security tools (password generator, hash)
More tools dropping every week
Tech Stack
- Next.js 16 — App Router
- WebAssembly — browser-side processing
- Vercel — deployment
- Supabase — database
- Tailwind CSS — styling
The Privacy Angle
Most online tools upload your files to a server.
Wrklyst processes everything locally — meaning:
No file uploads
No account needed
No paywalls
Always free
Still Building
This is an early version — still growing and
adding new tools regularly. Would love your
honest feedback.
