About PDFKill
PDFKill was built on a simple idea: the best PDF tool is one that gets out of your way. No paywalls after two uses. No forced sign-ups. No files sitting on someone's server longer than necessary. Just fast, private PDF processing — free for everyone.
Zero Retention
Your files are deleted from our servers the instant your processed file is ready. Not after an hour — immediately. No exceptions.
No Account Ever
We will never ask you to sign up, create an account, or provide an email address. Just upload and go.
Built for Speed
Our backend uses asynchronous task queues and distributed workers so your files are processed fast, even under heavy load.
Works Everywhere
No software to install. PDFKill runs entirely in your browser and is available in English, Spanish, French, Portuguese, and German.
