Why open PDF pages as PSD
PSD is the native format of Adobe Photoshop and is also read by Photopea, GIMP, Affinity Photo and other image editors. Turning PDF pages into PSD files lets designers retouch scanned pages, reuse a poster you only have as PDF, or use a page as the background layer of a new design.
What happens when you convert
Each page is drawn at 96, 150 or 300 DPI and saved as a flat PSD with one image layer in RGB colour. Files are uncompressed, so they open quickly in editors but take a lot of storage — especially at 300 DPI. Several pages are downloaded together as a ZIP, or one by one from the file list.
What you can edit
Everything on the page is one picture layer: you can paint, clone, retouch, crop, adjust colours and add new layers of text, shapes or photos on top. Existing text and shapes are not separate layers and cannot be edited as text.
Common problems and how to fix them
You expected separate layers: PDFs do not store Photoshop layers, so no converter can recreate them reliably. The file is huge: use 150 DPI for screen designs. Fonts in new text layers do not match: identify the font with your editor and install it on your computer.
Good habits
Work on a copy of the PSD, add new elements on separate layers, and export the final design as JPG, PNG or PDF for sharing.
