The Problem

Most PDF tools online — Smallpdf, iLovePDF, and the rest — require you to upload your file to their servers. That might be fine for a recipe PDF. It's not fine for a signed contract, a tax return, or anything with client data in it. You're handing your documents to a third party with no way to verify what happens to them.

What We Built

We built a PDF tool that runs entirely in the browser. Merge files, split out pages, compress a bloated scan — all of it happens locally on your device using WebAssembly. Nothing leaves your browser window. There's no server on our end receiving your files because nothing is ever sent.

What It Does

Files Never Leave Your Device

Everything runs in browser memory. No upload, no server, no third party. Your document doesn't go anywhere.

Drag-and-Drop Page Editor

See thumbnails of every page. Drag to reorder, rotate, delete, or split pages out into a separate file.

Compression Without Ruining the File

Shrinks large scans and embedded images by up to 80% while keeping text sharp and readable.

Works Offline

It's a PWA — install it once and use it on a plane, on a job site, or anywhere without internet. It doesn't need a connection to work.
