- Flow: PDF → PDF with edited metadata
How to use
Section titled “How to use”- Open a PDF — existing metadata is prefilled (a notice appears if it can’t be read); encrypted PDFs must be decrypted first.
- Edit the metadata fields; use “Clear all fields” to wipe all six Info values, and “Add custom field” for any extra key/value pair (prefilled from the first file’s existing custom keys).
- Download the updated PDF — or add more files and download the batch as a ZIP (per-file failures are skipped without stopping the rest).
Key details and limits
Section titled “Key details and limits”- XMP streams are preserved as-is; the Info dictionary fields (title/author/subject/keywords/creator/producer) are written, plus any custom key/value fields you add (keys ≤64 chars, values ≤256 chars; keys colliding with the six standard fields are ignored).
- Fields left blank overwrite the stored value with an empty one when saved — handy for wiping author/producer fingerprints.
- Saving updates the document’s ModDate to the save time; XMP dates are kept as-is, so the two can differ.
