Uploading a financial or personal PDF to a random website invites a question you would rather not ask: what happens to this file next? ThothBox answers that question by removing uploads from the equation. Every PDF tool here runs client-side in your browser, so the files you work with never leave your device and never touch a server.
There is no account, no queue, and no file that lingers on remote infrastructure after you finish. You open a tool, add your document directly from your device, and the work is done by your own browser, for free.
Below is a directory of the PDF tools available with no upload. Each one works locally on your files and requires no signup.
Merge PDF — Combine multiple PDF files into one document.
Split PDF — Split a PDF into separate pages or page ranges.
Compress PDF — Reduce a PDF’s file size while keeping quality.
