PDF metadata: see it, edit it, erase it

Every PDF carries an internal card holding the title, author, subject and keywords, the name of the application that created it and the library that wrote it, and the creation and last-modified times. You never see any of it while reading the file, but anyone who receives it sees the lot in one click on the document properties. A file exported from Word usually carries the account name of the machine it was written on.

Yes, and it is the first thing the tool does. The moment you drop the file we read its card in your browser and show all of it: title, author, subject, keywords, application, producer, both dates and the page count. Empty fields are marked Not set, so you know what your file says and what it does not before you decide anything.

It clears the whole card: name, title, subject, keywords, application, producer and both dates. The pages and their content are untouched, so the file reads exactly as before and nothing in it says who made it or when. This is the option to use before sending a document to someone who has no business knowing your computer's account name.

Yes. The old card is deleted from the file's structure rather than left orphaned inside it, and we verified that by searching the produced file's raw bytes for the original text and not finding it. We also remove the extra XMP packet that Adobe and Microsoft applications write, which is a second copy of the same details that many viewers prefer over the first.

Yes. The title and author are written in an encoding that carries Arabic letters in full inside the file's structure, so an Arabic title shows correctly in the viewer's title bar, in the document properties and in your device's search results. Writing them in plain Latin encoding would have turned every Arabic letter into a question mark.

The pages do not change: not their content, their order, or their size. The card is a few very small lines of text in the file's structure, so the output is close to the same size as the input, and erasing may make it slightly smaller because what was written is no longer there.

No. Reading the card and writing it both happen inside your browser, and the file never leaves your device at any point. That is what makes this safe for contracts and official documents you want your name off before sharing.
