Most PDFs have no title, so every program falls back to the filename. A screen reader announces "report-final-v3-b dot p d f" letter by letter. A document management system lists a shelf of files by filename. Search engines show the filename as the tab name. Writing a real title fixes all three at once, and the author, subject and keyword fields do the same job for anyone filing or searching a collection later.
PDF is the universal document format: it locks layout, fonts and images so a file looks identical on every device and printer. Scans, invoices, forms, e-books and reports all travel as PDF. Because a PDF is a container rather than an image, turning its pages into JPG or PNG pictures — or bundling pictures into a PDF — are among the most common file tasks there are.
Open a folder of PDFs and look at what the software knows about them. Almost all of them have an empty title field, which means every program that needs a name for the document falls back to the filename — and filenames are written for the person who saved the file, not for anyone who reads it afterwards.
The effect is worst where it matters most. A screen reader opening an untitled PDF announces the filename, character by character: "report dash final dash v three dash b". A document management system lists a hundred contracts by their upload names. A PDF opened in a browser puts the filename in the tab. One field fixes all three.
Author is what appears in document properties and in most search results within a DMS — an organisation name is often more useful there than a person’s. Subject is a one-line description; it is the field that shows up in file listings that offer a description column, and nearly nothing fills it in. Keywords are indexed by desktop search on both Windows and macOS, and by most document systems, which makes them the cheapest way to make a document findable by words that do not appear in its filename.
A PDF can carry a title and still be announced by filename, because a viewer only prefers the title when the document asks it to. That request is a separate flag, and it is the reason so many documents that look correctly titled still read out as gibberish. Writing a title here sets the flag too — it is a requirement of the accessibility standards for exactly this reason.
This is the opposite of Remove PDF Metadata, and the two get used at different moments: fill the fields in for documents you are publishing or filing, and clear them out of documents you are sending outside the organisation. Fields you leave blank here are left exactly as they were rather than wiped, so you can set a title without touching anything else.
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Yes. Add as many files as you like — each one is processed in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
No. Pages are copied at the object level — text, fonts, images and vector content are carried over as-is, without re-rendering. The output keeps the same sharpness and searchable text as the original.
It becomes the window or tab title in most PDF viewers, and it is what a screen reader announces when the document opens. Because some viewers only honour it when the file asks them to, setting a title here also sets the flag that tells viewers to prefer it over the filename.
