View Full Version : Enlarging Images with little/no Quality Loss

Hi, does anyone no of any programs that can enlarge images say from 800x600 to 1024x768? But still keeping the quality as good as possible. Thanks in advance.

no... thats not really possible without passing it through some blur and/or sharpen filters. Blur to soften the pixelation, sharpen to enchance the softened edges. I'd say give GIMP a shot.

Okay, I'll try that with Paint.NET tomorrow, thanks spikejones :)

There is no way to do it from a digital source without distortion as it has a defined quality.

So in a word...no. Sizing down is always best.

well... I just had another thought, since I've done it before. It requires printing a good quality photograph/image, the scanning it back into the computer at the highest dpi your scanner can handle. If you've got an all in one device - you're all set. Just use some no-gloss photo paper rather than document paper for best results.

There's this Photoshop plug-in called BlowUp by Alienskin, it's not lossless, but the quality loss is quite little, specially going from 800x600 to 1024x768. It's not free, though.

If you send me the picture that you want enlarged I could always give it a try for you.

I tried this yesterday with an 800x600 picture which I made 1280x1024. I sent it through 3 extreme sharpenings and it looked okay. :)

You can't squeeze blood from a turnip. It may look fine on the screen. When a upsized photo is printed, it will look pixelated and have artifacts.
