Client-side processing
This tool now runs entirely in your browser — files never leave your device.
Result preview & sharing
Preview your processed file before downloading, and share results via a secure link.
PDFs created in Word, InDesign, or Preview often contain the author's real name (from your OS account), creation dates, application versions, and unique XMP tracking IDs. Remove this before sharing sensitive documents to protect privacy.
You can edit 8 standard fields (title, author, subject, keywords, creation date, modification date, creator application, producer library) plus any custom fields in the PDF's Info dictionary.
XMP (Extensible Metadata Platform) is an XML-based metadata standard used by Adobe tools. Our XMP viewer shows 9 namespaces: Dublin Core, XMP Basic, Media Management, Adobe PDF, PDF/A ID, XMP Rights, Photoshop, Paged-Text, and PDF/X ID. You can strip all XMP with one click.
The privacy scanner auto-detects 7 types of exposed personal info: Author names (often OS usernames), Creator application, Producer library, timestamps, and XMP tracking IDs (DocumentID, InstanceID, edit History). Each issue has a severity level and a one-click fix, plus a Fix All button.
No. Metadata is stored separately from document content. Editing or removing it has no effect on text, images, or layout of the PDF.
Yes. Upload multiple PDF files and edit each via the file sidebar. Use quick actions like Anonymize to apply changes across all files. Download all processed files as a ZIP.
Yes. For single files, choose Remove all metadata on the mode selection screen. This strips both the Info dictionary and XMP metadata. A confirmation dialog prevents accidental removal.
Four one-click actions: Anonymize (clears Author, Creator, Producer), Set dates to now (updates both timestamps), Clear keywords (removes all keyword tags), and Strip XMP (removes all XMP metadata on save).
Yes. Click the JSON button to export structured metadata including filename, file size, page count, PDF version, all document info fields, and XMP properties grouped by namespace.
No. All processing happens 100% in your browser using pdf-lib and byte-scanning. Your files never leave your device. No account or signup required.
Yes. Click Add field to create arbitrary metadata properties in the PDF's Info dictionary. Enter a field name and value. Custom fields appear in the Custom Fields section and are saved into the PDF.
Keywords use a visual tag chip interface. Press Enter or comma to add a tag, click the X or press Backspace to remove. The tool also detects semicolons (non-standard separator) and suggests converting to commas.
