Hi, is it possible to achieve this without losing quality? Thanks

You will not loose quality if you do it with the right tools. But you need to understand that increasing the resolution of pixel images does not improve quality. What a program does is taking neighboring pixels and calculate in-between pixels. It's not magic à la CSI. The resulting image will be more blurry (at 100%).

So the answer is:

1. it's possible, yes.
2. Quality will not decrease.
3. Quality will not increase.
4. It makes only sense in very specific environments.
5. You need the right tool to achieve a correct result.
6. The quality of the starting picture needs to be excellent as any fault will be amplified.

Thanks, I understand that. But if the print size is 1metre wide x 2 metre high? Could it work? Image #248540746

You want to use it for a wall paper?

I suppose the picture you chose will be able to handle that. I have only looked at the preview but the structure of the picture is promising.

Yes as a full print on glass

What tool do you have for increasing the resolution?

Photoshop

That should work out... You need to check the picture after sizing at 100% especially at areas where there is a hard border.

Try out the different methods that Photoshop allows and choose what works best for you.
