Most free converters upload your file. Ours don't.
Type “PDF compressor” into Google and you'll get a wall of free-looking sites. They all work the same way: you upload your file, their server processes it, and you download the result. That model is fine for casual stuff, but the file lives — even briefly — on infrastructure you don't control. Server logs keep copies. Caches keep copies. Breaches happen.
Modern browsers can do the same work directly on your device. pdf-lib can merge and compress PDFs locally; the Web Crypto API can password-protect them with AES-256; RMBG-1.4, a real background-removal AI model, runs in WebAssembly and never sees your photo on a server. We just wired these capabilities into one-purpose pages so you don't have to install anything.
Open DevTools, switch to the Network tab, then use any tool on this site. Watch the request list while you process a file. It stays empty. There is no upload endpoint behind any of this — the file genuinely never leaves your tab.
Your file goes to a server, gets processed, sits in logs, returns to you.
Your browser does the work. The file stays where it started.

Frequently asked questions
Honest answers, including about the ads.
- Are my files really not uploaded?
- Yes. Open DevTools → Network tab and use any tool on the site — you'll see no file uploads. Everything happens in JavaScript and WebAssembly running on your device. There's no server-side processing pipeline behind any of these tools, so even if we wanted to keep your file, we never receive it in the first place.
- How does it process big PDFs and images without a server?
- Modern browsers are fast. pdf-lib can merge a 200-page PDF in about a second; canvas APIs can resize a 4000×3000 photo without breaking a sweat; the Web Crypto API can hash a file as fast as a native CLI. The practical ceiling is your device's memory — most laptops handle multi-hundred-MB jobs without issue.
- Why is it free?
- Display ads pay the bills. We don't have an upgrade tier, file-size paywall, or watermark we'd want to remove for money. The site loads quickly because most pages are static; the ads sit below the tool and don't gate the workflow.
- What about the ads and analytics — aren't those a privacy issue?
- They're a separate concern from your files. Ads (Google AdSense) and analytics (Google Analytics 4) work the same way they do on most free sites: cookies and identifiers, not file contents. Our claim is specifically about file flow — your PDF or photo never touches our servers. The full data list is in our privacy policy, with opt-out instructions.
- Can I use this for work or compliance-sensitive files?
- Most workflows that prohibit uploading documents to free converters are fine with browser-side processing because the file never leaves your machine. If your IT team needs proof, point them at the network log during use — there are no upload requests. For HIPAA, GDPR, or contractual data-handling requirements, talk to your compliance team; the site itself doesn't log file metadata.
- What happens if I close the tab?
- The work is gone. There's nothing on a server to recover from. Some tools save UI preferences (theme, last-used QR colors) to your browser's local storage so they're remembered next visit, but file contents are never persisted anywhere.
- Why isn't this just a desktop app?
- A desktop app would need installing, updating, signing, and platform builds — and would still be a binary you'd have to trust. The browser is already the most-sandboxed environment most people run, and our tools are useful exactly for the moments when you don't have time to install software. For heavy batch jobs (thousands of files at once), a desktop tool is genuinely faster.
