what image file type has the highest levels of compression without losing 'too much' quality?

Question

Hi all. I'm a big supporter of lightweight development; making applications (and websites) that use as little system resources and processing power as possible without sacrificing the performance of the application.

Therefore, I would like my resources to be as small in size as possible without negatively affecting their quality to a noticeable level. So I was curious as to which image file type has the highest levels of compression (and thus will be the smallest sized file), but wont be blurred or pixelated?

Answer 1

you might try .png

it uses a lossless data compresion method called DEFLATE.

it seems to work quite a bit better than .gif and.jpg

Answer 2

It's not possible, sorry. You can't enlarge images without losing quality, not in Photoshop or any other software. If you enlarge it a little you might get away with it - but to a trained eye the quality will still suffer. The vector route is a red herring. Vectors are rescable, but the very act of converting a raster image made of pixels into a vector using some kind of vector tracing software will destroy the quality. However, you could actually get away with printing them quite large, because large images are not usually inspected closely. Say you printed it at 120dpi, that would give you at least a 25" x 16" - might not be the best quality, but it will do. Don't try to rescale them in Photoshop - find a printer who knows what they are doing, and give them the maximum file size you have.

Answer 3

When using paint to edit pics, saving it as .JPG makes it pixelated looking or blurred blah blah. When I use photoshop, it's as clear as how I saved it.



I would say without photoshop, .PNG is good. That's what I use when I use a laptop that has no photoshop/photo editing software when I ned to edit some pics. I resize them and save them as .PNG type



gosh I sound so weird XD
