Smaller file size gif or jpeg

Instead of colors, JPEG files support up to around 16 million color so this is the best format for large photographs printed in brochures, flyers and books that still want to look clear and smooth.

Sometimes when uploaded to the web you may notice the image comes in blurry at first but then clears up and becomes super crisp. The more complex the image the better to use JPEG for. The extension to use for your graphic files will depend on your project.

Think about the project and research what image extension will be best for your project output. Programs such as Adobe Creative Suite will help you to import and export what you need.

You can select the action to perform if the aspect ratio of the source image and your chosen size does not match - center and crop the image, stretch the image to fit, or force the original aspect ratio.

Online image resizer Ezgif's online image resizer will resize, crop, or flip animated gifs and other images, with the same quality and speed as professional software, without the need to buy and install anything.

Webp is superior to JPG for lossy compression of photographs. It is superior to PNG for lossless compression. However, the Safari browser does not yet support it. Scream at Apple until they agree to support webp. An often hotly debated issue is whether JPG should ever be used for archiving images you care about. For a take on this issue, see "How bad is JPG?

However, in contrast with common TIFF usage, it looks for patterns in the image that it can use to compress file size. The compression is exactly reversible, so the image is recovered exactly.

GIF creates a table of up to colors from a pool of 16 million. If the image has fewer than colors, GIF can render the image exactly. When the image contains many colors, GIF uses any of several algorithms to approximate the colors in the image with the limited palette of colors available.

Better algorithms search the image to find an optimum set of colors. Sometimes GIF uses the nearest color to represent each pixel, and sometimes it uses "error diffusion" to adjust the color of nearby pixels to correct for the error in each pixel. GIF achieves compression in two ways. First, it reduces the number of colors of color-rich images, thereby reducing the number of bits needed per pixel, as just described.

Second, it replaces commonly occurring patters, especially large areas of uniform color, with a short abbreviation. Thus, GIF is "lossless" only for images with colors or less. For a rich, true color image, GIF may "lose" JPG is optimized for photographs and similar continuous tone images that contain many, many colors. GIF compression is unkind to such images. JPG works by analyzing images and discarding kinds of information that the eye is least likely to notice.

It stores information as 24 bit color. The degree of compression is adjustable. At small compression levels of photographic images, it is very difficult for the eye to discern any difference from the original, even at extreme magnification.
