PDF to JSON, Watermark & Metadata Editor

Work with one PDF in three useful ways without leaving the browser. Export structured JSON for data review, add text or image watermarks to selected pages, and update document metadata such as title, author, subject, keywords, creator, and language before downloading a fresh PDF copy.

How to Use This Tool

Upload PDF and Choose a Task

Upload one PDF, preview its pages, choose a page range if needed, then switch between JSON export, watermark editing, and metadata editing. The file stays in the browser and each output downloads as a new file when you are ready.

JSON export reads the text layer already inside the PDF. Watermarking and metadata editing create a new downloadable PDF without sending the file to a server.

Page range

Leave blank for all pages. Watermarking and JSON export both respect the selected page range.

Current workflow note

Tip: Use PDF to JSON when you need structured page text and page-level details. Use watermark mode when the document needs ownership, draft, review, sample, or branding marks. Use metadata mode when title, author, or subject details need cleanup.

JSON detail level

Detailed mode exports item-level text positions and page metrics. Simple mode keeps the file lighter.

Exports page number, size, text summary, and optional text items.
Useful when you want content inspection, structured review, or lightweight PDF-to-data conversion.
Scanned PDFs without a text layer can still export page details, but their text content may be limited.

Text watermarks are embedded directly into the PDF. Image watermarks use the uploaded image and apply it to the selected pages only.
