🚀 I Built GoPDFTools — A Privacy-First PDF & Image Toolbox That Runs Entirely in the Browser

GoPDF Tools — Fri, 28 Nov 2025 09:49:04 +0000

Hey devs! I recently launched a side-project called GoPDFTools, and I thought it would be fun to share how and why I built it.

👉 Live here: https://gopdftools.io/?ref=devto

It’s a fast, lightweight set of PDF & image utilities that run 100% client-side using JavaScript and WebAssembly. No servers. No storage. No tracking. Everything happens directly in your browser.

🧱 The Problem I Wanted to Solve

Most online PDF tools force users to upload files to a backend server. That leads to:

Slow conversions
Privacy concerns
File size limits
Annoying ads
Rate limits or “premium” prompts

For something as simple as merging PDFs or converting JPG to PDF, this felt unnecessary — especially when modern browsers are more than capable of handling it locally.

So I decided to build a privacy-first version powered by client-side processing.

💡 No Backend

Everything runs offline.
The backend = your browser.

🛠️ What the Tool Can Do

Right now GoPDFTools supports:

Convert Images → PDF
Compress JPG/PNG locally
JPG → PDF
PNG → PDF
Merge PDFs
Split PDFs
Compress PDFs
Delete/Reorder PDF pages
PDF → JPG

All done entirely client-side.

🧪 Try it Out

Would love for you to try it and let me know:

Speed improvements?

Browser compatibility issues?

Feature requests?

WASM optimization ideas?

I’m already working on more tools and improvements — and I’d love the DEV.to community’s input.
