Images inside PDFs are stored as embedded objects — usually JPEG or PNG streams. The Rankato extractor walks every page, finds every image object, and outputs them at their embedded resolution and format. Original quality preserved; no re-encoding.
Format preservation
Images are extracted in their embedded format (JPEG stays JPEG, PNG stays PNG). No re-encoding — you get exactly what the PDF creator embedded. If you need a specific output format, run the extracted images through the Bulk Image Converter.
Naming and metadata
Files are named source-p1-img1.jpg, source-p2-img1.jpg, etc. — encoding the page number and per-page image index. Preview each image before downloading, or grab a ZIP of everything.
Vector images
The tool extracts raster (bitmap) images only. Vector graphics inside the PDF stay embedded — extracting them as SVG would require rewriting PDF drawing commands to SVG paths, which we've deferred. For that use case, open the PDF in Illustrator or Inkscape.
