Taking screenshots of photos embedded inside a PDF results in blurry, compressed images restricted to your monitor display resolution.
Extracting the actual embedded asset preserves the full megapixel resolution, original color profile, and transparent PNG channels. Here is how to do it locally on your Mac.
Why taking screenshots of PDF images ruins quality
A photo embedded in a PDF might be a 12-megapixel print asset, but taking a screenshot caps it at your screen's pixel dimensions.
Direct extraction pulls the raw image streams directly from the PDF file, giving you the untouched original quality.

常见问题
Does extracting images lower their original quality?
No. Direct extraction exports the exact image bytes stored inside the PDF container without recompression.
Can transparent PNG graphics be extracted?
Yes. Any transparency masks and alpha channels embedded in the PDF are fully preserved in the exported PNG files.
Can I extract images from multi-page PDFs all at once?
Yes, File Acture scans through hundreds of pages and exports every embedded picture into a designated folder.
Do my PDF documents get uploaded to a server?
No. File Acture operates 100% locally on your computer with zero internet connectivity required.
