I've attached simple sample.

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

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).
