Sunting Metadata PDF
Kemas kini tajuk, pengarang, subjek, dan kata kunci yang disimpan dalam PDF.
Cara ia berfungsi
Muat naik PDF anda, sunting mana-mana medan (telah diisi terlebih dahulu daripada metadata sedia ada fail itu), kemudian muat turun hasilnya.
Metadata apa yang boleh saya ubah?
Tajuk, pengarang, subjek, dan kata kunci — sifat dokumen yang kebanyakan pembaca PDF paparkan di bawah "Document Properties" atau "File Info".
Adakah ini akan mengubah rupa PDF?
Tidak — metadata ialah maklumat tidak kelihatan tentang fail itu, bukan kandungannya. Halaman, teks, dan imej tidak akan terjejas.
Why would I want to change a PDF's metadata?
To remove a previous author's name before sharing, add proper keywords for searchability, or fix a wrong title that shows up in browser tabs and file previews.
Can I clear a field completely instead of changing it?
Yes — leave the field empty before downloading and it's saved as blank.
Does this affect the creation or modification date shown by my OS?
It updates the PDF's internal document properties, not your operating system's file-system timestamps, which are set separately when the new file is saved to disk.
Does this touch XMP metadata or custom fields?
No — it only edits the classic document-info fields (title, author, subject, keywords), the same ones most "File Info" dialogs show. Some PDFs, especially ones made in Adobe apps, also carry a separate XMP metadata stream or custom vendor fields; this tool doesn't read or write those, so old values there can survive even after you update the fields here.
Can old metadata leak information I don't want to share?
Yes. PDFs exported from Word, Google Docs, or Acrobat often keep the real name of whoever created or last saved the file — sometimes a company name too — even if you never typed it in yourself. Overwriting the author and title fields here removes that before you send the file anywhere.
Does the title or keywords field affect how my PDF shows up in Google?
It can. Search engines that index a PDF often use its Title field as the headline in search results, and a blank title usually falls back to the raw file name. Filling in Title and Keywords with accurate text won't guarantee rankings, but it gives search engines something better to show than "scan0042.pdf".
