See and change a PDF's title, author, subject and keywords. Nothing is uploaded.
After you add a PDF, the table lists what the file stores about itself: title, author, subject, keywords, the program that created it, the program that produced the final file, the creation and modification dates in UTC, the page count, the PDF version from the file header, whether it is encrypted, and whether it carries an XMP metadata block. A detail the file does not hold reads None. A date that is stored but cannot be read as a date reads unreadable. The first four entries are the ones you can edit. The rest are shown so you know what else the file says about itself, and you can remove creator, producer and both dates with one tick box.
The tool edits the document information entries, the classic Title, Author, Subject and Keywords fields that every PDF reader shows under Properties. Type a new value to change one, clear a box to remove it, or press Remove all of these to clear all four. Each value can be up to 1000 characters, and accented letters and other Unicode characters are kept. Surrounding spaces are trimmed. The pages, the text and the pictures are not touched, and the file is written out again in full. The creation and modification dates stay as they were unless you tick the box, so editing a title does not move the modification date. Nothing is saved until you press Save PDF, and a copy with the same details is produced if you save without changing anything.
Many PDFs store the same details a second time as an XMP metadata block. The table says when the file has one. This tool does not change that block, so a reader that prefers XMP, such as the document properties of some desktop programs, may still show the old title or author after you edit the fields here. It is also not a privacy scrubber. It does not look at the content of the pages, the names of annotation authors, attached files, form data or hidden text, and older copies of the details can survive inside the file, for example in an XMP block or in a version saved by an earlier incremental update. To remove what is on a page for good, use the picture-only copy from Compress PDF.
The PDF is read and written by your browser in this tab. There is no upload step and no server that receives the file. The page counts visits with Google Analytics, using rough size groups such as 1 to 10 MB, never a file name or any of the details you type. The tool asks before opening a file over 200 MB and works on one file at a time. A password-protected PDF is shown as encrypted, with its details blank, and cannot be edited, because its text is scrambled and this tool does not remove passwords. Take the password off in your PDF reader first, then add the file again.
Add the PDF, clear the Author box, and press Save PDF. To clear title, author, subject and keywords at once press Remove all of these. Tick Also remove creator, producer and dates to clear those too.
The file probably has an XMP metadata block, and the reader shows that instead of the entries edited here. The table says Yes next to XMP metadata block when that is the case. This tool leaves the block as it is.
No. The pages, text and pictures are untouched. The file is written again in full, so its size can differ by a few KB, and the modification date stays as it was unless you tick the box to remove dates.
No. The tool shows it as encrypted with blank details and does not save changes. Remove the password in your PDF reader, then add the file again.
Creator is the program the document was first made in, such as a word processor, and Producer is the program that turned it into a PDF, such as a print driver. They are shown for information, and one tick box removes both along with the two dates.
No. It changes the information entries only. Names can also sit in the text, in comments, in attached files and in the XMP block. If the content is sensitive, check the file itself, or use the picture-only copy from Compress PDF.
