I built a PDF tool that never sees your documents (and no, it's not a subscription)

Here's a scenario you probably know.

You need to convert a PDF to Word. You find a "free" online tool. You upload your document, wait a few seconds, and download the file.

Then you spend the next week wondering where your sensitive contract or personal resume just went.

Most online PDF tools work by uploading your file to a server. That means your document sits on someone else's computer, often without any guarantee of when or if it gets deleted. For anything containing personal data, financial info, or private work, that's a non-starter.

So I built a different kind of PDF tool.

Meet PDF Architect. It does two main things:

• Converts PDFs to editable Word documents while preserving page breaks and formatting.
• Turns static PDFs into interactive fillable forms.

But the important part is how it works. Everything happens directly in your browser. Your files never leave your device. There are no server uploads, no cloud processing, no temporary storage on some remote machine. Once you close the tab, the document is gone from memory.

This is possible because the tool uses client-side libraries like pdf-lib and PDF.js. The entire conversion engine runs locally, using your computer's own resources. This means:

• Zero privacy risk.
• No file size limits (your browser is the only constraint).
• Works offline after the first page load.

The tool is completely free, with no signup, no watermarks, and no "premium" tier that secretly uploads your data.

You can try it here: PDF Architect

I built this because I was tired of workarounds that compromise privacy. If you regularly handle sensitive PDFs, give it a shot.

Two questions for you:

1. What's the one feature you wish PDF tools would stop charging for?
2. Do you currently use any client-side document tools?
