Privacy Policy
Last updated: June 2026
Pdfhubtool is built on a simple principle: your files are yours alone. Unlike cloud-based competitors that upload your documents to their servers for processing, every tool on this site runs entirely inside your browser. We architected it this way by design — not as a marketing claim, but as a technical guarantee.
No Data Collection
Pdfhubtool does not collect, store, transmit, or process any files you convert. All file processing happens exclusively inside your web browser using JavaScript and WebAssembly APIs. Your files never leave your device.
No Account Required
We do not require you to create an account, provide an email address, or submit any personal information to use any tool on this site. You are completely anonymous.
Local Browser Processing
All conversions — PDF to JPG, image compression, merging, splitting, format conversion — are performed using client-side libraries (pdf-lib, PDF.js, Canvas API). These libraries run entirely in your browser's JavaScript engine. No server receives your files at any point during processing.
No Cookies or Tracking
We do not use advertising cookies, tracking pixels, or third-party analytics scripts that profile your behavior. We do not sell or share data with advertisers because we collect none.
CDN Libraries
Some processing libraries (pdf-lib, PDF.js) are loaded from public CDN providers (unpkg.com, cdnjs.cloudflare.com). These CDNs may log standard server access logs (your IP address and request time) as part of normal CDN operation. We have no control over or access to these logs. You can self-host these libraries by running the project locally.
No File Size Limits or Quotas
Because we do not process files on our servers, we impose no artificial file size limits. The practical limit is your device's available RAM and your browser's capabilities.
Children's Privacy
This service does not knowingly collect any information from children under 13. Since we collect no personal information from any user, we meet COPPA requirements by default.
Changes to This Policy
If we ever change our privacy practices in a material way, we will update this page with a new effective date. Since our core promise is zero data collection, any change that compromises that promise would be clearly disclosed.

Technical verification
You can verify our privacy claims yourself. Open your browser's DevTools (F12), go to the Network tab, and convert a file. You'll see no outbound requests to any server carrying your file data. The only network requests are loading the initial page assets and CDN-hosted JavaScript libraries — never your file contents.
