Are the extracted images the originals or screenshots of the page?

They are the image objects stored inside the PDF, not renders of the page. A JPEG in the PDF is saved with exactly the same bytes, and an image stored at 100 by 50 pixels is exported at 100 by 50 pixels even when the page draws it at 20 by 10 points. The page may scale, rotate or crop an image, so the file can look different from what you see on the page.

Why are some images listed but not exported?

Each one has its reason in the table and in the CSV report. The tool does not decode CCITT fax, JBIG2 or Crypt filters, does not convert CMYK, Lab, Separation or DeviceN pixel data, and lists inline images written directly into the page content without extracting them. A non-JPEG image whose soft mask is a different size, JPEG-compressed or premultiplied is not exported, because its transparency could not be applied exactly. CMYK JPEGs are still copied as stored.

What does Skip duplicate images do?

With it on, byte-identical images are saved once, even when the PDF stores them as separate objects or paints them on several pages, and the report still lists every placement against that one file. With it off, every exported placement gets its own file, named by page and placement number. Switching it does not rescan the PDF.

What happens to transparency?

For PNG output, a soft mask or stencil mask the same size as the image, or a colour-key mask, becomes the PNG's alpha channel, so transparent areas stay transparent. A stencil image that has no colour of its own is saved as black on transparent. JPEG files cannot hold transparency, so a JPEG with a separate mask is saved as stored and the report says the mask is not included.

Which images does it find?

Images painted by each page's content, including images inside form XObjects, along with the size each one is drawn at. Images used only inside annotations, patterns or Type 3 fonts are not searched, and images listed in a page's resources but never painted are left out. If part of a page cannot be read, the tool names that page instead of presenting the result as complete.

PDFs up to 50 MB, and up to 200 pages per extraction: use the page range to work through longer files. Each image decoded to PNG can have up to 50 megapixels, one extraction's images can total 250 MB, and the ZIP can reach 400 MB. Images with 16 bits per sample are saved as 8-bit PNG. An extraction that runs longer than 2 minutes stops, and encrypted or password-protected PDFs are refused.

Does my PDF leave my device?

No. The PDF is read by a worker in this browser tab and is not uploaded. Clear removes the file, the previews and the report from the page.

PDF Image Extractor

Pull the actual image objects out of a PDF instead of screenshotting its pages. Each supported embedded bitmap is saved at its stored pixel size: JPEG and JPEG 2000 data is copied exactly as stored, and other supported images become PNG files, with soft masks, stencil masks and colour-key masks turned into transparency when the tool can apply them exactly. Choose a page range, skip duplicates that repeat across pages, preview the exported images, and get a report of each placement with its page, drawn size in points and stored pixel size.

Skip duplicate images

On: identical images are saved once and every placement still appears in the report. Off: one file per exported placement.

Embedded imagesNone yet

Images appear here after extraction, each at its stored pixel size.

Exports the image objects stored inside the PDF, not screenshots of pages: JPEG and JPEG 2000 data is copied byte for byte, and other supported images are decoded to PNG at their stored pixel size. Unsupported colour spaces, filters and masks, inline images and a JPEG's separate transparency mask are reported instead of exported. A page can show an image scaled or clipped, so an exported file may look different from the page.
