PdfAddImage
Security and No Upload
The safest file transfer is the one that never happens. PdfAddImage keeps the editing workflow inside your browser.
Browser-only processing
PDF preview uses pdf.js in the browser, image placement uses an editor canvas as an interaction layer, and export uses pdf-lib locally.
The app does not send your PDF or overlay images to PdfAddImage servers for processing.
Original PDF quality
Export starts from the original PDF bytes and draws image overlays onto the target pages.
PdfAddImage does not export by taking a canvas screenshot of the page, so the original PDF text and vector content remain sharp.
Transparent image support
Transparent PNG images are supported and keep their alpha channel in the exported PDF.
WebP images are converted locally to PNG for PDF export; JPEG images are embedded as JPEG.
