Hello!

I need help on how to save an image (as jpg or gif) without losing its
Quality. I am using Paint Shop Pro 7 and I tried to blend two images
Together after applying the "feather" effect.

But once I try to save it as jpg even after applying the lowest
Compression for best quality, it's still not that great. Is there a way
To save it where it preserves the quality especially on the blending
Part of the image??

I'd appreciate any help. Thank you!

Don't save it as .jpg

... save it as .bmp

JPGs use a lossy compression format, this means that information is lost forever. So if you compress a picture to 90% and it looks bad, you can't just resave it with full quality and expect it to look good again.

GIFs are based on only 256 colorsso complicted pictures will be of low quality

If you can't use BMPs due to the large file size, see if PNGs are available... its like a GIFs, which also allows animation, but uses the 24-bit color (which is 16,777,216 colors rather than just 256).
