Designers sometimes try to edit PDFs in Photoshop because they have Photoshop open. It works in the sense that Photoshop opens the file. It doesn't work in the sense that the result is no longer a real PDF — it's a giant rasterised image dressed up as one.
What Photoshop does to PDFs
Open a PDF in Photoshop: it asks you to choose a page and resolution, then renders it as a flat image. Text becomes pixels. Layout is fixed. You can paint over things, but you can't edit text or update fields.
The resulting 'PDF' is essentially a JPG inside a PDF wrapper. Huge filesize, no searchability, no future editability.
When Photoshop is right
If your goal is to repurpose PDF content as a graphic — extract a page as an image for a marketing piece, manipulate visually — Photoshop's rasterisation is appropriate. The result isn't a PDF anymore; it's an image. Use it for that.
When to use a real PDF editor
For PDFs that need to stay PDFs — edits to text, signatures, page management, conversion — use Flint. Text stays as text, layout stays as layout, future editability preserved.
Flint runs in any browser; no Adobe Creative Cloud subscription needed.
FAQ
Can I save a Photoshop-edited PDF as a 'real' PDF?
Photoshop's PDF export creates a PDF, but the content is rasterised. It's a PDF that contains an image, not a PDF with editable text. Future editing requires going back to the original or starting over.
What about Acrobat instead of Photoshop?
Acrobat edits PDFs as PDFs — that's its actual purpose. If you have Creative Cloud, Acrobat is the right Adobe tool for PDF editing, not Photoshop.
Is Flint a Photoshop alternative?
Not for image editing. For PDF editing specifically, yes — Flint does what Photoshop people think they want when they try to edit a PDF in Photoshop.
Photoshop is for images. Flint is for PDFs. Use the right tool.
