When I want to save digital images on my computer, I want the one that is the best quality and colour. So could you tell me which type of file is the best one for that? (ex. jpeg, and .png)
What you're asking doesn't make any sense. Where are you saving them from? The web? A camera? No matter what you save something as, you're not gonna get better colours or quality. Both jpegs and png files maintain the original resolution, and with png there's zero artifacting, so I don't see why you would need to use any other form of compression, which is simply what these different file types mean.
No they don't... you can watch the jpeg quality lessen -.-. The whole point of the jpeg file format is to compress the size of the image. It sacrifices detail to do that. Photographers were sick of filling up everything they had just because of their pictures, so they made jpeg (the p stands for photographers). Png I'm not sure about, I don't believe there's any compression. I save as tiff because my teacher said so. There's absolutely no compression and you can save layers if you so choose. Color doesn't always make a difference. Depending on what browser you use, you could be seeing completely different color quality than someone else. In other words: online color relies on browser as much as file format (monitor color aside). That's why a lot of pr0fessionals make prints to show their potential clients...
Bitmap with no compression > TIFF > TGA > PNG = JPG High (negliable difference to the human eye) > JPG Low > Compressed Bitmap > GIF
yes it is, but to the human eye without zooming its unnoticable...unless its a damn huge image with a print quality resolution
PNG is suited for web design. And when you save files with large resolutions, the size of it can go up to 5MB on a .png. While it can be 900KB on a .jpg.
There's no point in going .png. Especially if you're going to be uploading to the web. What's the point in uploading a 5MB file when you can upload a 900KB file? Most people won't wait for a 5MB image to load. And on top of it, they look exactly the same. So there is no benefit with .png.
For online, jpeg is the best way to go. If you want to save your images on your computer, tiff is the way to go. If you save your image as a tiff, you won't lose quality, especially if you want to send it somewhere to print.
