Sharpening an image without noise.

I want to sharpen a blurry image. The problem is the noise of the image will also be clearly visible. How can I sharpen it without the noise? Thank you!

Take your original image. Use either Despeckle (see our tutorial on the Descpeckle effect) or Gaussian Blur (see our tutorials on the Selective Gaussian blur and the Gaussian blur) first to remove some details from the picture (the noise) and only after that sharpen it moderately so that not much more noise is shown.

Sharpen text in a .jpg image - potentially using GIMP, but open to alternatives (but don't have Photoshop)?

Probably an impossible dream - looking at the service tag ID in an eBay photo, that seems deliberately blurred, to make this unreadable. I'm not getting much that's useful from Filter/Sharpen, on just the cutout section that includes the 2 lines of text.. Any other suggestions about what to try? Or directions from which to approach the problem? I'm not an experienced graphics person (am slowly picking up a few tips & tricks in GIMP), but I am far from capable (much less 'expert') with the pkg. I have tried: Using an online image enhancer GIMP's Sharpen/Filter. I think it was caused by: As previously, I believe that the eBay doesn't want (for no reasonable reason, TBH) potential buyers to be able to read the Service Tag ID, and be able to look up the factory-original config
