Have you tried Topaz Lab's DeJpeg? Most Topaz plug-in work with Affinity.

Hi impact,.

 

a very old trick may help you.

 

Open the image and go to photo develop,
use the noise reduction tool in tab details.

 

Example

Filters > Noise > Denoise
 

Adjusting the Luminance Denoise slider seems to do a good / quick fix on your sample
 

(Tip: Tick the "Extreme" checkbox for a greater range to the effect, if needed)

 

PS You can also add this as a Live Filter Layer

Due to the fact that Boris Johnson is now our Prime Minister, punctuation, spelling and grammar will never be worried about ever again.  We now have far bigger problems to be concerned about.

You can extract text from images with Acrobat, using OCR option. I've done this with scanned documents -- useful for in-document PDF searching. Other scanning/OCR software will probably do likewise.

 

Then cut/paste text into Affinity as you like.

No, but there is a free trial, and it is one of their cheaper plug-ins. ($29.99).
