Baseline Optimized creates a file with optimized color and a slightly smaller file size. Progressive displays a series of increasingly detailed versions of the image (you specify how many) as it downloads. (Not all web browsers support optimized and Progressive JPEG images.)
What is a baseline in Photoshop?
Baseline Optimized optimizes the color quality of the image and produces a slightly smaller file size (2 to 8% – a little more compression, or slightly faster loading). All modern web browsers support it, **Both Standard and Optimized produce good quality images, so it’s really just a matter of choice.”
What does optimized mean in Photoshop?
Optimize as JPEG
Choose JPEG from the optimization format menu. To optimize to a specific file size, click the arrow to the right of the Preset menu, and then click Optimize To File Size. … The higher the Quality setting, the more detail is preserved in the optimized image, but the larger the file size.

What is the meaning of TIFF in Photoshop?
Tagged-Image File Format (TIFF, TIF) is used to exchange files between applications and computer platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. … In Photoshop, TIFF image files have a bit depth of 8, 16, or 32 bits per channel.
What is a baseline JPEG?
A baseline JPEG is a file stored as one top-to-bottom scan of an image, unlike the more complex progressive JPEG. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
What is a baseline standard?
A baseline is a minimum level of security that a system, network, or device must adhere to. Baselines are usually mapped to industry standards. As an example, an organization might specify that all computer systems comply with a minimum Trusted Computer System Evaluation Criteria (TCSEC) C2 standard.
What does scans mean in Photoshop?
Progressive (Scanning): Pro: Downloads the images in passes, or “scans,” allowing it to be viewed before it’s completely downloaded. The first scan will be blurry and low resolution, and with each scan the image quality improves.
