Whenever I save my images in Photoshop, they never seem to be high enough quality from my perspective. Even when I save it as a png, it still has rough edges/pixels. So I was wondering, what's the best way to save them?

Hmm, .png always yields the best results for me.
Would you mind possibly posting a few examples. We can try to save them in different ways to see what might get the best result. |

i usually save mine png because it comes out better then jpeg.
save it as png if you don't mind it taking up a little more space. but for normal photos, like everyday pictures, i usually use jpeg. i've only used gif and tiff a couple times. i usually only use gif for animations. |

PNG's are lossless in that they retain quality, but also find certain "chunks" of an image to optimize (find patterns within an image to optimize). This is WAY, WAY better than saving in JPEG format if your sole purpose is to retain quality.
JPEG's are lossy, so they're better suited for compressing photographic images. If you save a JPEG of a graphic with both photographic images and text, you'll see those pixelly edges around the text. This can be alleviated (slightly) by saving at JPEG quality 12 on Photoshop, but you might as well save with .PNG. Another good file to save as is a .TIFF (or .TIF). They are completely lossless, and you can choose whether or not to compress or not. A quick comparison of different file types of a vector image (500x313) that I just whipped up: TIFF (no LZW compression) 481KB PNG 97.9KB JPEG (Quality: 12) 124KB GIF 37.7KB As you can see, TIFF's have the biggest file size. Even the 12 quality JPEG is less than half its size. The PNG, while being lossless, compresses parts of the image...and since the picture I used was a vector (meaning, it had many similar colours that it could group together), it was able to compress the image to be even smaller than a 12 quality JPEG. Bottom line: TIFF: Completely lossless; may or may not be compressed - BEST QUALITY if you're looking for no loss of data. PNG: Completely lossless; compresses patterns within an image JPEG: Lossy, compresses; good for photographic images. Generally this, if saved at a high enough quality, will be sufficient for web use. GIF: Now why the hell would you use a GIF, save for the possibility of a blinking avatar? |
