Practical image guides

Understand the image before you export it.

Clear explanations for dimensions, formats, compression, resizing, and the metadata hidden inside a photo.

A practical starting set for feed posts, Stories, thumbnails, banners, and profile pictures.

The best format depends on whether your priority is compatibility, transparency, sharp graphics, or a small web file.

Every smaller file involves a tradeoff. The practical goal is to remove bytes viewers will not notice.

The picture may not show your location, but an embedded metadata tag still can.

Use the Photos app for a quick share or a browser tool when you need a specific file size.

When width and height change by different percentages, faces and objects become distorted. Keep the aspect ratio intact.

When a form specifies 50 KB, 100 KB, or 200 KB, use a target-size tool instead of repeatedly changing share settings.

Start with a strong 16:9 image, one clear subject, and a small amount of highly readable text.
