About JunglePDF
57 file tools that run entirely inside your browser. No uploads, no accounts, no limits — and no server that could keep a copy of your files even if someone wanted it to.
Why we built it
Almost every free file converter online works the same way: you hand it your file, it travels to a server you know nothing about, something happens there, and a download link comes back. That model is fine for a holiday photo and genuinely uncomfortable for a signed contract, a payslip, a passport scan, or a medical report — which is exactly the kind of document people most often need to merge, compress, or convert.
Browsers no longer need that server. The Canvas API can re-encode images, the Web Audio API can decode and rewrite sound, WebAssembly runs a real build of FFmpeg, and pdf-lib and pdf.js can take a PDF apart and put it back together. JunglePDF is what you get when you build the usual toolbox on top of those instead.
How it works
When you drop a file onto a tool here, it is read into your browser's memory and processed on your own machine. Nothing is uploaded, so there is no queue to wait in, no file-size cap imposed by bandwidth, and nothing left on someone else's infrastructure after you close the tab. Once the page has loaded, most tools keep working with the network switched off entirely.
It also means speed is your hardware's speed. A large video conversion is slower here than on a server farm, and we say so on the tool rather than hiding it behind a spinner.
What we will not do
- Upload your files.Not for processing, not for “optimisation”, not temporarily. There is no upload endpoint to send them to.
- Ask you to sign up. No account, no email, no daily quota, no watermark on the output.
- Gate a feature behind a plan. Every tool is complete as shipped.
- Overstate what a tool does. Where something has a real limit — PDF compression being structural only, video trimming cutting on keyframes, PDF-to-Text not being OCR — the tool says so before you run it.
How it stays free
Running JunglePDF costs almost nothing, because the expensive part — the processing — happens on your device rather than on hardware we pay for. Hosting static files is cheap enough that advertising covers it, and ads only load if you accept them in the consent banner. Declining means no third-party script runs at all. See the privacy policy for the details.
The tools

Who builds it
JunglePDF is built and maintained by DailyOrbit Studio, an independent studio. It is not a front end for someone else's conversion API, and there is no company behind it collecting your documents — the operator is one small team, reachable at the address below.
That matters more here than it would on most sites. A tool that promises your files never leave your device is only worth as much as the people making the promise, so it should be obvious who they are.
