I built free browser-based tools — files never leave your device

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.
