Extract images from a PDF
A PDF made from photos, a scanned document or a brochure carries its pictures as separate objects. This preset takes them out exactly as they are stored instead of rendering the pages: a JPEG inside the PDF comes out as the same JPEG, byte for byte, with nothing re-encoded and nothing lost; pictures stored as raw or deflated samples come out as PNG, transparency included where the PDF has a soft mask; JPEG 2000 comes out as .jp2.
Options
Every picture is named after the page it sits on, and you get them all in one ZIP (or the file itself when there is only one). Icons under 32 pixels are skipped. Everything runs in your browser with pdf-lib; the file never leaves your device.
Tips
- For scans, this is the lossless way out: the scanner's JPEG comes back untouched, sharper than any re-render.
- A page drawn as text and vectors has no picture to extract; switch the mode to "Pages as images" to render it instead.
- Pictures compressed with JBIG2 or CCITT (fax-style black-and-white scans) cannot be unpacked here; the result says how many were left out.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
Frequently asked questions
- Is the image quality reduced?
- No. JPEG pictures are copied as they are; others are written as lossless PNG. Nothing is rendered or recompressed.
- Why do I get fewer pictures than I see on the page?
- The same picture used on several pages is stored once and comes out once; logos drawn as vectors and tiny icons are not pictures in the PDF's sense.
