What browser-local processing means
When you choose a PDF, the browser gives the page temporary access to that file for the current session. JavaScript loaded from the website reads the document into device memory, performs the requested operation, and creates a downloadable result. The original file is not changed. Closing or refreshing the page clears the working session unless the browser itself retains a normal download.
The webpage and its processing libraries still have to load over the internet. Privacy refers to the document content: the selected PDF is not posted to an Inqita conversion endpoint. This distinction matters because “online tool” does not automatically mean “server upload.”
Which operations fit this model
Page-level work is particularly suitable for local processing. Merging, splitting, rotating, reordering, deleting pages, adding page numbers, and converting pages to images can all be completed on the device. Some document conversions are more limited because a browser does not include every font, office-layout engine, OCR model, or proprietary file feature available to desktop software.
Each Inqita tool therefore describes its supported formats, practical size limits, and compatibility notes instead of claiming that every possible PDF will behave identically.
How to verify the privacy claim
You can open the browser developer tools, select the Network panel, clear the existing requests, and then use a PDF tool. The browser will show requests for page assets or privacy-preserving analytics, but the chosen document should not appear as an uploaded request body. For extremely sensitive or regulated documents, use approved offline software and follow your organization’s handling policy.
Keep the original and inspect important output
PDF files may contain forms, signatures, bookmarks, attachments, metadata, layers, and embedded fonts. A page operation can preserve the visible result while changing or dropping an interactive feature. Keep the source document, open the downloaded result, confirm page order and readability, and test forms or signatures before relying on the new file.
