Your browser can do it.
Every other file tool makes you upload your files to a server first. Your browser doesn't need to — it's more than capable of doing it all itself. PDF, image, audio, video, text, code, handled right here in your tab. Your files never leave your device.
Tools chain together: watermark a PDF, then protect it, then compress it, without ever downloading in between.
Every other tool uploads your files.
Smallpdf, iLovePDF, PDF24, CloudConvert. They all process your files on their servers. We do it in this browser tab.
Files stay on your device.
The engine runs in your browser: pdf-lib, ffmpeg.wasm, Web Crypto, Canvas. Open DevTools and watch the network tab stay quiet.
Free, no upsell, no signup.
No paywalls, no “upgrade to Pro for larger files,” no mandatory account before downloading. Just the tools.
Open and verifiable.
The code that handles your file is right here in this page. Read it, audit it, or self-host the whole thing.
How we convert PDF↔Word/Excel/PowerPoint without uploading your file.
Most PDF tools that promise “PDF → Word” run LibreOffice on a server and need your file uploaded. We run the same LibreOffice. We just put it inside your browser tab.
There is no free lunch: the LibreOffice engine is roughly 300 MB. We lazy-load it on first use of any Office conversion tool, then cache it forever. From the second conversion onward, it’s instant.
For everything else (merge, split, sign, compress, OCR, watermark, page numbers, redact, crop, organize, convert, trim audio or video, hash, encrypt), there is no bundle to download and your file never leaves this tab.
