Reduce image size for faster pages while keeping enough sharpness for the displayed dimensions.
When this guide is useful
An image much larger than the space where it appears usually wastes bytes. Resizing and compressing together often gives a better result.
Think about where the file will be used. Messaging, social media, websites, presentations and archiving can require different sizes and formats.
How to decide without overcomplicating it
Start with the approximate display dimensions, then reduce the file size while checking text, logos and fine edges.
Always start with a copy of the original file. That gives you a reference and lets you try another setting without losing the best-quality source.
How to check whether the result is good
Make a first attempt with moderate settings. Then review the full result, especially areas with small text, faces, music, transitions or fine detail.

Common mistakes to avoid
Avoid using exactly the same compression setting for every image. Photos, illustrations and text-heavy graphics behave differently.
Checklist before downloading or sharing
