Converting jpg or png to high quality in Libre

users
#1

Hi my esteemed listmates,

I need to take a graphic I download (with permission) off a Website and
make it 1920x1080, or larger by the same ratio so its quality will be
higher.

It would be even better if I could convert it into 3840x2160.

Has anyone been able to accomplish this in Libre Writer? Libre Draw? Or a
FREE Windows tool?

I understand Photoshop can do that but I don't have Photoshop so I need to
accomplish this with something simpler like MS Paint.

Has anyone achieved these improved graphic results with MS Paint?

If so, could you pls share the steps?

I'm guessing it can be done in GIMP but GIMP and I are not in sympatico.

Thank you kindly.

Charles.

GIMP or ImageMagick are what I would use for this.  With ImageMagick, you can use the "convert" command to scale the image.  Just keep in mind, when you upscale an image, its quality will suffer since image data is being "created".   If you're not worried about that, either of those tools would work.  It's been a VERY long time since I've done this BUT there was a free Windows utility you could install that would add image scaling to the context menu of an image file.  So, you could right-click the file and choose the "scale" (whatever it's called) menu option to scale it up or down.

I just don't know if that utility exists still or if it's compatible with Windows 10 or 11.

Peace...

Thanks for posting that information!   That's the utility I was thinking of!   It had been sooo long since I last used it, I even forgot the name. :slight_smile:

Thanks again!

Peace...
