How DropIn PDF Keeps Files Private

Learn how DropIn PDF processes PDFs and images locally in your browser so document contents do not upload to a server.

Private PDF tools should not require an upload queue

DropIn PDF is built for quick document chores where privacy matters. For supported tools, your PDFs and images are processed inside the browser tab instead of being uploaded to a server for processing. That makes it useful for applications, receipts, scans, records, school packets, and other files you do not want sitting in an unknown upload queue.

Privacy proof

  • Files are read by your browser from your device.
  • Supported PDF and image operations run locally with browser APIs, JavaScript, and WebAssembly.
  • The output is created in the page and downloaded back to your device.
  • DropIn PDF does not need a server upload queue, account, or watermark step for supported tools.
  • Analytics events are limited to product usage actions and do not include filenames, file contents, file sizes, page counts, or document text.

Common uses

  • Merge application packets, scans, IDs, receipts, and records without sending the source files to a server.
  • Convert WebP, JPG, PNG, and PDF pages in the browser when you need a quick private download.
  • Use the privacy proof page as a starting point before choosing a specific no-upload PDF tool.

How it works

  1. Load the tool page: Your browser downloads the DropIn PDF app code, then the file operation can run locally in the tab.
  2. Choose files from your device: Selected files are handed to the browser page for local processing. DropIn PDF does not need to upload the source files to a server.
  3. Create and download the result: The merged PDF, converted file, extracted pages, or OCR text is generated locally and downloaded back to your device.

Frequently asked questions

Do my PDF files upload to DropIn PDF?

No. Supported tools process files locally in your browser, so the source files do not need to upload to a server.

Does DropIn PDF store my files?

No. DropIn PDF does not store your selected files or generated downloads on a server for supported browser-side operations.

Does analytics receive my document data?

No. Product analytics are limited to usage actions such as file selection or download clicks. Filenames, file contents, file sizes, page counts, and extracted document text are not sent.

Can I use it for sensitive documents?

The browser-local design is intended for sensitive everyday documents, but you should still use your own judgment for regulated, legal, medical, or employer-controlled files.
