Best Practices for Pristine Images
Image and Video Manager can simplify your workflow by reducing the number of derivative images needed.
To deliver the best-quality derivative versions for each end user, use a higher-quality pristine (or original) image. To take full advantage of Image and Video Manager optimizations, we have created the following “best practices” for image format, quality, dimension, file size, and color profile. Please keep in mind these are general guidelines.
- We recommend high-quality JPEGs, PNGs (for images with transparency), or GIFs but any web format will work.
- We do not support Photoshop (PSD), RAW, or SVG formats.
- We recommend providing Image and Video Manager with the highest-quality imagery you have.
- For JPEGs, we suggest a quality level of 95, but nothing lower than 85.
- In general, we suggest dimensions 2,000 px–4,000 px wide.
- If you happen to know the largest dimension you will use, and resizing is part of your process, we suggest using those exact dimensions as your pristine dimensions.
- In terms of byte size, generally we recommend high-quality pristines in the 500 KB–5 MB range.
- We recommend providing images in sRGB color profile.
- If this color profile is not available, Image and Video Manager will color correct your images, but this may increase the time to process the image
Is there a tool to help analyze my images?
Yes, you can use Perceptual Quality Preview to analyze pristine images and get some hints about optimization. Perceptual quality lightens the weight of your images by applying the maximum level of byte reduction and compression that is imperceptible to the human eye.
This will help you select the perceptual quality settings you want to use in your Image and Video Manager policies.
