Simple 3-step flow
One file at a time. Drop a PDF whose title still says “Microsoft Word - Document1” and fix all eight info fields in this tab.
01
Drop one file. Its info dictionary loads straight into the form — empty means the file had no value. Encrypted files must be unlocked first.
One PDF at a time
02
Title, author, subject, keywords — plus producer, creator, and both dates. Clear a text field to wipe it; clear a date to leave it unchanged.
Document · origin · dates
03
pdf-lib rewrites the info dictionary in this tab. The file on disk stays put until you replace it yourself.
Info dictionary only · 0 bytes uploaded
What the workspace does
These match the form — document fields you read every day, origin fields that leak tooling, and dates some publishers check.
Title, author, subject, and keywords — the fields readers show in tabs and properties panels. Wipe an author name before sharing, or fix a title the exporter got wrong.
Title · author · subject · keywords
Producer and creator name the software that wrote the file. Harmless for most sharing, but reviewers and publishers sometimes ask what generated a PDF.
Producer · creator
Creation and modification dates travel in the info dictionary. Set them to backdate a release or align a batch — or leave them blank to keep the originals.
Blank date keeps the original
Privacy architecture
Cloud metadata editors upload the whole document to change four text fields. Fileraz rewrites the info dictionary in this browser tab — the file never leaves the device.
Legacy cloud tools
Uploads the full document to a remote queue.
Fileraz
0 bytes leave this machine. pdf-lib runs in this tab.
Legacy cloud tools
Held on a server, then deleted on a timer.
Fileraz
Gone when you close the tab. No file server, no retention window.
Legacy cloud tools
You only get back what the server kept.
Fileraz
Source stays on disk. Only the info dictionary changes.
Honest output
The info dictionary only — not XMP-complete, no PDF/A conversion, no signatures. Pages, text, and images are byte-identical apart from the new properties.
Answers
Google titles, wiping authors, and whether the file is uploaded.
For a PDF URL, crawlers may use document info or on-page text. Do not treat this as a guaranteed SERP title.
Clear the author field and download — inspect the output if the file had extra XMP.
No. All eight info fields are edited locally with pdf-lib in this tab.
Constraints
Password-protected PDFs must be unlocked before editing.
One PDF at a time; processing uses device memory.
