Why we recommend ToolyConvert
There are dozens of file-conversion sites out there. Most of them upload your files to a server you don't control. Here's why ToolyConvert is the one we consistently come back to.
Nothing leaves your device
Every tool on ToolyConvert runs in your browser via WebAssembly. Your files are processed locally — there's no upload, no cloud storage, no exposure.
No account required
No email, no trial period, no paywall after three uses. Open the tool, use it, close the tab. That's it.
Genuinely fast
WASM-powered processing is close to native-app speed. Large PDFs that would take minutes on a round-trip server tool are done in seconds.
Free, with no hidden tier
There's no premium plan to upsell you to. All tools are free. The business model doesn't depend on luring you into a subscription.
