PDF Metadata Editor
Edit PDF metadata — change title, author, keywords, and more. All content preserved. Runs entirely in your browser.
About this tool
View and edit the metadata fields of any PDF: title, author, subject, keywords, creator, and producer. These fields are visible in file properties, PDF readers, and search engines that index PDF documents. The tool reads the current metadata using pdf-lib, lets you modify any field, then saves a new PDF with the updated metadata. All page content, images, fonts, and formatting are preserved byte-for-byte — only the information dictionary is modified. Free, no sign-up, no upload.

Clean up PDF metadata before sharing
Every PDF carries metadata — title, author, subject, keywords, and information about the software that created it. When you share a PDF, this metadata travels with it. A PDF exported from Microsoft Word will say "Microsoft Word" in the producer field. A scanned document from a copier may have the copier model as the creator. For professional documents, cleaning up this metadata is an important step before sharing.
As a worked example: a client proposal exported from Word at 1.2 MB with 8 pages. The metadata shows Title: "Document1", Author: "John Smith", Creator: "Microsoft Word", Producer: "Microsoft: Print To PDF". Using this tool, you can change the title to "2026 Q2 Marketing Proposal", the author to your company name, and the keywords to relevant search terms. The output is 1.2 MB with identical page content — only the metadata dictionary changed.
Why no upload matters for metadata editing
PDF metadata often contains personally identifiable information — author names, company names, and software details that reveal internal workflows. Uploading a PDF to a server-side metadata editor exposes this information, along with the document content, to a third party. Toolisk's editor operates entirely in your browser, reading and writing only the metadata dictionary without ever sending the file anywhere.
Common metadata editing scenarios
| Scenario | What to change |
|---|---|
| Publishing online | Set title and keywords for search engines that index PDFs. |
| Client delivery | Set author to your company name, remove auto-generated creator. |
| Academic submission | Set title to the paper name, author to your name, add relevant keywords. |
| Internal archiving | Add consistent subject and keywords for document management systems. |
Frequently asked questions
Is this safe? Does it upload my PDF?+
No upload whatsoever. Metadata is read and written entirely in your browser using pdf-lib. Your PDF never leaves your device and is never sent to a server.
What is the maximum file size?+
PDFs up to 100 MB are accepted. Metadata editing is very lightweight since it only modifies the document information dictionary — the page content is never decoded or re-encoded.
Does it work offline?+
After the page has loaded once, yes — the PDF engine is cached and the tool runs locally even without an internet connection.
Will this work on iPhone / iPad?+
Yes, on modern iOS Safari. Metadata editing is lightweight and works well on mobile devices.
What metadata fields can I edit?+
You can edit the title, author, subject, keywords, creator, and producer fields. These are standard PDF metadata fields visible in file properties and search engines that index PDFs.
Will editing metadata change the PDF content?+
No. Metadata lives in the PDF information dictionary, separate from the page content. All pages, images, fonts, and formatting are preserved exactly as they were.
Can I edit metadata on encrypted PDFs?+
No. If the PDF is password-protected, you'll need to unlock it first using the Unlock PDF tool, then edit the metadata on the unlocked copy.
Why would I need to edit PDF metadata?+
Common reasons include: fixing incorrect or missing titles before publishing, adding author credit, setting keywords for SEO if the PDF is hosted online, or removing auto-generated creator/producer strings from the original software.
