How to resize pictures without ruining the quality?

Question

I am just wondering. When I usually re size a picture to make it big, it ruins the quality. What should I use to not ruin the quality? Like this website www.ewallpapers.com they have many backgrounds at different sizes but they are still the same quality.

Answer 1

To maintain image resizing without distortion, use a vector graphic editor to make your backgrounds.



http://www.inkscape.org/download/ (Very good for vectored graphics)



The only other way is to make the highest quality image to begin with so any increase will not pixelate.

Answer 2

About the only way is with a telephoto lens. Resizing pictures digitally degrades quality - period. It's most likely that the backgrounds you're looking at were originally the sizes you're seeing. (You can sample the same picture at different sizes and end up with different-sized files, all of about the same quality. But once you do that, resizing them degrades the quality.)

Answer 3

You can't. ewallpapers starts with the largest size then resizes them smaller.



There is no way you an enlarge a picture without ruining the quality. You cannot resize images smaller without losing quality either. Data is irrevocably lost.

Answer 4

Your computer (unless a Mac) already has a software on it called, "Microsoft Office Picture Manager" -Open your photo with it (by right clicking on the photo > open with... and choose Microsoft Office Picture Manager) -Click the 'Edit Pictures...' button -Then the 'Compress Pictures' -And select 'documents' -Press OK -What's important is that you DON'T replace the original, so after pressing OK, go FILE > Save As... And save as a copy And when it asks you if you want to save the original, click NO.

Answer 5

Whenever you reduce the size of an image make sure "constrain proportions" is checked in whatever program you are using. Also save it to a lossless format like .tif .tga. or .png



You can't help but lose some of the detail from going to large to smaller since it will have less pixel resolution to work with...unless it is vector-based in which case it can be resized up or down without quality loss.

Answer 6

i'm pretty sure there are ways of increasing image size without losing too much quality. This however is something that is probably impossible for a general computer user to be able to do as the program or application used would be built up on pretty complex algorithms, something which our computers may not support or are very expensive

Answer 7

Have you tried using something like "print key" or "print screen"? That way you can copy the Original pics and crop them or change them any way you like with your photo system on your computer...
