Getting pictures out of a PDF
PDFs often contain pictures you want to reuse — a chart from a report, a product photo from a catalog, a logo from a brochure. Taking a screenshot gives you a blurry, cropped copy at screen resolution; extracting the embedded image gives you the picture at the size it was stored.
How extraction works
PDF Studio walks through each page, finds the image objects placed on it, and saves every one as its own PNG file, named after your document with the image number and page number. Identical images that appear several times — a logo repeated on every page, for example — are detected by comparing their pixel data and saved only once, and tiny images smaller than 10 pixels (such as decorative bullets) are skipped.
You can download images one by one or use Download All. Extraction runs in your browser, so the PDF is not uploaded.
About the file format and quality
All images are saved as PNG, even if they were stored as JPEG inside the PDF. PNG keeps every pixel exactly, so there is no further quality loss, but photographs saved as PNG can be larger than the original compressed data. If you need smaller files, convert them to JPG afterwards in an image editor.
Images keep their original pixel dimensions. Vector graphics — charts and drawings made of lines and shapes rather than pictures — are not images in this sense, so they are not extracted; use PDF to JPG to capture those as a page image.
Scanned documents and other cases
A scanned PDF usually contains one large image per page, so extraction returns the full-page scans rather than smaller pictures. If you want complete pages as images in any case, PDF to JPG renders every page for you. Respect copyright: having the file does not mean you may reuse its images everywhere.
