As answered by people managing Bundle.tools and PDF24.
Bundle.tools's answer
Most online PDF and image tools upload your files to their servers, which is slow for big files and a risk for sensitive ones. Bundle processes everything on your device, so there's no upload wait and nothing stored or shared. It's also free with no limits or accounts, and open source (MIT), so you can read the code or run your own copy.
Bundle.tools's answer
Everything runs in your browser. Your files are never uploaded to a server, and a strict content security policy enforces that, not just a promise. There is no sign-up, no ads, no watermarks and no paid tier, and a privacy-proof page lets you verify the claim yourself.
Bundle.tools's answer
Anyone who needs a quick PDF, image or file conversion without handing their documents to a third party. That includes people handling personal paperwork like IDs and forms, students and freelancers, and developers who want fast JSON, cron and timestamp utilities without installing anything.
Bundle.tools's answer
Astro for the static site shell, Svelte for the interactive tools, TypeScript, and plain CSS. Heavy work runs in Web Workers, with WebAssembly where needed. It's deployed on Cloudflare Workers.

Bundle.tools's answer
Privacy-focused tools exist, but they are spread across many sites, with no single place for everything. I built Bundle for myself and add tools as I need them. Everything runs on your device and nothing is uploaded.
