Browser-only PDF tools

PDF tools. No upload. No account. No bullshit.
Every tool runs in a Web Worker inside this tab, on your machine.
- 12tools, all free
- 0bytes uploaded
- 0network requests
Nothing leaves this tab. Go and check.
Every site that asks you to upload a PDF also promises not to look at it. This one makes a duller promise: it never receives the file, so there is nothing to look at. You can check that in about a minute.
It runs on your machine
PDFium, compiled to WebAssembly, renders pages in a Web Worker. pdf-lib reads and writes the file structure in the page itself. Either way the bytes go from your disk into your own memory and back out as a download.
Watch the Network tab
Open developer tools, switch to Network, then run any tool on any file. The request count does not move. The page is served with a Content-Security-Policy that blocks outbound connections anyway.
Then pull the plug
Turn the network off and reload. Tools you have already opened keep working, because they were never running anywhere else. A site that uploads cannot survive that test.
Every tool works the same way: drop the file, run it, download it.
