What PDF Metadata helps you do

View and edit a PDF's document properties such as title, author, subject and keywords. Cleaning or setting metadata helps with file organization and can remove leftover author details before sharing. The fields are read from the file when it loads and written into a new copy on save.

Metadata editing runs locally in your browser; your PDF is not uploaded to Haivix.

How it works

A PDF stores positioned drawing instructions rather than flowing paragraphs, which is why editing one is different from editing a document. Page content, fonts, images and annotations are separate objects, and a page only carries a text layer if the producer wrote one. Most tools here rebuild or render the file in your browser with pdf-lib and pdf.js; the formats that need a full office engine, such as Word, Excel, PowerPoint, PDF/A and HTML, use the Haivix service and say so in their privacy note. Every tool writes a new file and leaves the original untouched. Because content is placed by coordinates, extraction often returns text runs in visual order rather than sentences, and columns or tables can arrive interleaved.

How to use PDF Metadata

Load the PDF and read its current metadata fields.
Edit the title, author, subject or keywords as needed.
Save and download the updated PDF.
Reopen the file and confirm the properties in your viewer.

When to use it

Remove a software-generated author name before sharing a file.
Set a proper title so the document shows correctly in viewers.
Add keywords for internal search or archiving.
Standardize metadata across a batch of exported PDFs.
Clear an old subject line after repurposing a template.
Correct an author name that was inherited from a source file.

When not to use it

Do not use it to remove visible content; it edits properties only.
Do not assume it removes XMP metadata that the form does not expose.
Do not treat metadata cleanup as anonymization.

Example

A PDF whose author field reads the exporting application can be edited to a neutral or correct value. Setting the title changes what many viewers show in their window title and recent-files list. Keywords entered as a comma-separated string are split into separate entries on save.

What you can do with PDF Metadata

Read the current title, author, subject and keywords.
Edit any of the four fields.
Accept keywords as a comma-separated list.
Save the changes into a new PDF.
Leave the page content untouched.
Run the editing locally in the browser.

Example: work on a copy and check the output

Keep the original file. These tools produce a download rather than editing in place, so a failed operation never damages the source.

Check whether the PDF has a real text layer before relying on extraction. A scan is an image, so text tools return little or nothing until OCR has run.

Unlock encrypted files first. A password-protected PDF cannot be reordered, cropped or annotated until it has been opened with the correct password.

Review the output before sending it on. Fonts can substitute, overlays do not always remove what is underneath, and page boxes can shift content near the edges.

Note the page size and orientation before laying anything out. A mixed document can contain portrait and landscape pages, and a tool that assumes one size may crop or offset the others.

Keep a note of the operation and its settings. If a recipient questions the result, reproducing it from the original is faster than guessing which options were used.

What to know before you start

Metadata editing changes document properties only and does not alter page content.
Some producers embed hidden metadata that this tool does not expose.
It edits the common document information fields, not arbitrary XMP properties.
Metadata cleanup alone does not guarantee anonymity.
Editing properties does not remove embedded thumbnails or attached files.

Common mistakes

Assuming metadata cleanup removes hidden document history.
Leaving the author field blank and expecting the producer name to disappear.
Using commas inside a single keyword.
Forgetting to reopen the saved file to verify the change.

Troubleshooting

If a field is empty after loading, the source had no value there.

If the old title still appears, the viewer may be showing a cached copy.

If keywords are not split, check the comma separators.

If the file will not load, it may be encrypted and need unlocking first.
