Extract Embedded Images from Client PDFs to Check Resolution Before Press
A client-supplied PDF that looks fine on screen can contain downsampled images that will print poorly — and the only way to verify embedded image resolution and color mode before committing to press is to get the images out of the PDF. Deliteful extracts every embedded image from any PDF as a separate file, so your prepress preflight can include a direct resolution check.
Prepress preflight tools like Acrobat Pro's preflight profiles and Pitstop can flag low-resolution images in client-supplied PDFs, but they require a license, training, and access to the workstation where they are installed. When a job arrives late and the press operator needs a quick check on whether the supplied photography is actually 300 DPI or was upsampled from a 72 DPI web image, extracting the images and checking their properties in any image editor is faster and more definitive than running a full preflight report. The extracted file's pixel dimensions and document DPI setting tell you what you need to know in seconds.
Deliteful extracts embedded images in their original stored format — the same pixel dimensions and color data that will be used during RIP processing. A CMYK JPEG embedded at 300 DPI extracts as a CMYK JPEG at 300 DPI; an RGB image that a client incorrectly supplied in an otherwise CMYK document extracts as RGB, making the color mode mismatch immediately visible in the file properties. At 1 credit per PDF, the extraction cost is negligible relative to the cost of reprinting a job that went to press with bad image data.

Frequently asked questions
- Will extracted images reflect the actual resolution stored in the PDF, or the resolution set in the PDF page properties?
- Extracted images reflect the actual pixel dimensions and embedded resolution of each image as stored inside the PDF — not the page size or output resolution. A 600x400px image placed to fill a full page will extract as 600x400px regardless of how large it appears on the page, making it immediately clear whether the image has sufficient resolution for the intended print size.
- Will CMYK images extract as CMYK, and RGB images as RGB?
- Yes. Images are extracted in their original embedded color mode. This makes color mode mismatches — such as an RGB image embedded in an otherwise CMYK document — immediately detectable by checking the extracted file's properties in Photoshop or any image editor.
- Can I use this to recover images from a client PDF when they cannot supply the original native files?
- Yes. If a client cannot locate their original InDesign package or image folder, extracting images from their supplied PDF gives you the highest-resolution version of the assets available in the file. This is not a substitute for original files but is often sufficient for reprints or minor modifications.
- Will extraction work on PDF files that have already been through a RIP or were output as PostScript-derived PDFs?
- Deliteful extracts embedded raster images from any valid PDF file. PostScript-derived and RIP-output PDFs are supported. However, some RIP workflows flatten or merge image data during processing — in those cases, extracted images may reflect the post-RIP state rather than the original placed assets.
