Your files are processed here, on your device
We do not send the contents of your files or text to any server: everything is processed in your browser’s memory. No account is needed, there is no daily quota and we use no analytics or trackers. Each tool has size limits to protect your device’s memory.
A connection is only needed to load the site. After that you can disconnect and the tools keep working (some previews may need the connection). Hosting may receive technical visit data. Favorites store only tool identifiers in this browser.
How we handle your data →How to use this tool
- Load the PDF and review the four available fields.
- Edit title, author, subject or keywords; an empty field leaves that standard value blank.
- Save the copy and inspect its properties again to verify the change.

Edit PDF metadata: uses and practical guidance
Editing PDF metadata changes descriptive fields such as title, author, subject and keywords. It helps a shared copy carry a clearer identity when opened in a reader or organized in a document collection. These values are part of the PDF’s internal information. Changing them does not rename the downloaded file or rewrite words visibly printed on its pages. Prepare descriptions that reflect the document you are actually distributing.
Choose a meaningful title and avoid adding personal details that do not need to be published. Before saving, check which supported fields should change and which should retain their existing values according to the available options. Correcting an outdated author label can improve identification, but it does not establish new authorship. Descriptive labels can be edited by someone who did not write the content, so they should not be treated as independent evidence of who created the document.
The tool does not remove every possible metadata representation or erase XMP, annotations and other personal information from a PDF. Anonymizing a document requires a broader review than these four fields. Save the copy and inspect its properties again to confirm the supported values. Verify existing signatures, since saving changes can invalidate them. Retain the original and visually check the pages as well: updating descriptive information should still leave the content you intended to share available and readable in the resulting file.
A practical check before using the result
For a trial report, enter clearly recognizable replacement values and inspect the download with PDF properties. This verifies supported fields without depending on a single reader, which may favour file names or other metadata. If a viewer still shows an earlier title, investigate that difference before repeatedly editing values. Ensure the descriptions correspond to the submitted version and avoid keywords unrelated to its content. Record edited fields when several people prepare a document collection. Descriptive consistency helps organization, while actual document content remains the basis for understanding what each file contains.
Settings and limits
Select a PDF, review its existing metadata and edit the title, author, subject and keywords. Save a copy; the original file stays on your device. Maximum 25 MB and 500 pages. Editing a PDF invalidates existing digital signatures. XMP and other document data are not modified.
Frequently asked questions
Does this remove all personal information?
No. It changes only four fields in the standard information dictionary. Other metadata, attachments and page contents may still contain information.
Guides
Check titles, authors and dimensions and understand the scope of metadata editing.
Use your browser’s Network tab and offline mode to see whether a PDF, image or video tool uploads your file, and learn what that test can and cannot prove.
Inspect the properties, edit what you can, delete the pages you cannot share, add a watermark and test the final copy.
