Privacy Policy
At PDFsHero, your privacy is not just a feature—it is our core architectural foundation. Read precisely how we ensure your data never leaves your device.
Information We Do Not Collect
Unlike traditional cloud-based PDF tools, **PDFsHero does not store, upload, or transmit your files**. When you use our tools to merge, compress, watermark, or convert files, we do not require you to create an account, log in, or provide any personal identification information to access our core services.
We do not collect the content of your documents, metadata from your files, or any sensitive data contained within the materials you process using our platform.
Browser-Based Processing
PDFsHero utilizes modern WebAssembly (Wasm) and client-side JavaScript technologies. This means that **100% of the file processing occurs locally within your own web browser**.
- Your files never touch our servers.
- Your documents are never queued in an online pool.
- Once you download your processed file, no trace of it exists anywhere except on your local machine.
Third-Party Services
To maintain and improve our website, we may use standard third-party analytics and hosting tools (such as Vercel) that collect basic, anonymized web traffic data (e.g., page views, browser type).
Additionally, we may partner with third-party advertising networks that utilize cookies to serve relevant non-intrusive advertisements. These third-party services do not have access to your PDF files or processing activities.
Security
Because your files are handled entirely on your local device, the security of your documents relies on the security of your own browser and operating system. We serve our application over HTTPS to guarantee the integrity of the tool code delivered to your browser.
