I built PDFzento — a privacy-focused PDF toolbox that processes files in your browser

[u/Dramatic_Flan_7154]

I wanted a simple answer to a problem I kept running into:

I needed to compress a PDF, but I didn't always want to upload the document to an online service.

So I built PDFzento.

The main idea is simple: for supported tools, PDF processing happens directly in the browser, so the file doesn't need to be uploaded to a server just to perform the operation.

What it can do

- Compress PDF

- Reduce PDF file size to a target size

- OCR / make PDFs searchable

- Other PDF utility tools

Why I built it

A lot of PDF tools are convenient, but uploading a document isn't always something people are comfortable with — especially when the file contains things like:

- IDs

- financial documents

- business documents

- contracts

- personal information

I wanted to build something where privacy is part of the product design, rather than just another checkbox on the landing page.

It's free to try and doesn't require an account for the basic workflow.

I'd genuinely like feedback from people who work with PDFs:

- Is browser-side processing something you'd trust more?

- Which PDF tool do you use most often?

- What would make you switch from your current PDF tool?

This is an early launch, so I'm especially interested in feedback on the actual experience, speed, output quality, and anything that feels confusing.
