Optimizing Images (for web)
Saving Images for Web
- File – Export – Export As
- Select file format (JPG, PNG, GIF, SVG)
- On JPG, adjust the Quality to be as low as possible before altering the image appearance (60% is best all around)
- Make sure the image size (width and height) is small enough for web (see image size guide)
- Set Metadata to: "None"
- Set Color Space to: "Convert to sRGB"
- Click Export
- Save image filename in lowercases and dashes only.
Optimizing your images is a best practice for web usage because optimized images take up less disk space and load faster on a webpage. When you optimize an image you are not lowering the quality/appearance of the image, but rather just removing unnecessary data like comments and color profiles.
Using ImageOptim (for extensions: jpg, gif, png, jpeg)
- Download ImageOptim (for Macs only)
- Open ImageOptim
- Add images or folders by dragging and dropping in or by clicking the "+" button on the left
- Click "Again" until all files are at Savings 0%
- To remove files from the list just select and delete (backspace).
SVG Save Settings
SVGs can be very picky so please follow the exact instructions below in Adobe Illustrator.
- Create a new file in Illustrator as the final web size the graphic should be. You may need to start with just the width set (i.e. 300px or 630px).
- Drag the graphic (vector) into the new file and resize to fit the horizontal / width edges.
- Crop the excess vertical height out so the graphic fits edge-to-edge.
- If there are several SVGs that should align with each other in a row then use the same canvas (width and height pixels dimensions) for all of them and align the vectors to top, bottom, or center of the canvas.
- Remove all excess layers and convert all type layers to outline / vector format (select type and right click to see this option).
- This prevents the fonts from being unrecognizable by various computers & browsers.
- Save out the file as SVG and use the setting guides (see image below).
- Name the file in lowercase and dashes only.
- Upload the SVG into OU Campus in the desired image folder and publish.
- Add the SVG as a regular image inside of the editing area of a page.
- If the graphic has text on it is recommended to add all text into the alt Image Description.
- SVGs will expand to the full area width allowed so they display best inside of a grid snippet (i.e. Three Columns).
