Convert PDF to layered PSD
Do you want to edit a PDF document, or use some of its graphics elsewhere? Let's see, how to convert it into a PSD with layers, so we can work with it in Photoshop!
PDF to PSD
If you try to open a PSD file in Photoshop, it will rasterize it: each page will be a bitmap, consisting only of pixels.
Today (the beginning of 2020), Photopea is the best tool to convert PDF documents to Photoshop files. Go to Photopea.com to start a free online photo editor. If you see a Welcome Screen, close it by pressing the Cross in the top right corner.
Open a PDF file from your computer: click File - Open (in the top left corner), then find and select the PSD file (or use drag and drop).
You should see the graphics of the PDF file in front of you, one page next to another. Photopea converted pages into artboards. Text was made into Type Layers (you can see its font name, font size, color etc.). Bitmaps became Smart Objects (you can save them in the original resolution). Vector graphics became Vector Shapes (with a correct fill, stroke style, gradients etc.).
Now, just click File - Save As PSD. And we are done!
