Use this PDF metadata editor to view existing document information and edit PDF metadata before sharing or archiving a file. Change the title, author, subject, keywords, dates, creator, producer, and custom properties.
PDF readers, operating systems, document searches, and archive workflows can use metadata to identify and organize a file. Editing it lets you correct inaccurate details or add missing document information.
KissPDF changes document properties in browser memory without altering visible page content. Your PDF is never uploaded, and the edited document is downloaded as a separate copy.
Choose a PDF, view its current metadata, change the fields you need, and download an updated copy.
Select the PDF whose metadata you want to view and edit.
Change standard document properties or add custom field names and values.
KissPDF synchronizes the supported PDF Info and XMP values locally in your browser.
Save the edited copy while keeping your original document unchanged.
Practical guide
Use the PDF metadata editor to view and change a document title, author, subject, keywords, creator, producer, dates, and custom PDF properties without editing visible page content.
PDF metadata can describe a document without appearing on its pages. Common properties include the title, author, subject, keywords, creator application, PDF producer, and creation or modification dates. Some files also contain organization-specific custom fields.
PDF readers may obtain metadata from the older document information dictionary or from an XMP metadata packet. KissPDF updates both representations for supported standard fields so different readers are less likely to show conflicting values.
Metadata editing does not intentionally render, crop, rotate, or rearrange pages. Empty fields are removed from the document properties instead of being saved as blank strings.
Correcting metadata is different from privacy cleanup. If the goal is to remove hidden authorship and workflow information before sharing, use the dedicated metadata remover instead. Rewriting a signed PDF invalidates its existing signatures.
Clear answers based on how this tool actually works.
Select a PDF, change the document properties shown in the form, add any custom fields you need, and click Update PDF Metadata.
Yes. Title and Author are standard fields and are synchronized between PDF document properties and XMP metadata.
Yes. Add a custom field name and value. Existing custom document properties are also displayed and can be changed or removed.
The filename belongs to the downloaded file, while Title is an internal PDF property that readers may display in the window title or document information panel.
No intentional page-content operation is performed. The PDF container is rewritten, but page count, dimensions, and visible content are retained.
No. Metadata reading and writing run locally in your browser.
