Resize Image to 320x240

Width and height reduce exactly to 4:3, which is less wide than 16:9 and preserves more vertical context around the same subject. That makes 320x240 useful for classic screenshots, tutorial stills, and media thumbnails where interface height or scene structure matters.

Choose a source whose usable 4:3 crop already reaches 320x240. A larger screenshot gives you room to move toward the instructional control or action, but the small result can only preserve text and interface detail that were sharp in the original.

At 320x240, text inside screenshots must remain readable after reduction to QVGA dimensions. The exact 4:3 landscape frame should keep its subject clear outside the enlarged editor preview.

PNG is preferable for interface captures because it keeps small controls and hard edges cleaner, while JPG or WebP suits camera images. Transparency rarely helps a complete screenshot, but it can support isolated diagram elements or overlays that must sit on another background.

Large labels may survive at 320x240, but menus, body text, and small controls often become too small to read. Crop toward the relevant interface region instead of shrinking an entire desktop capture, and judge the exported still at native size before using it in a tutorial.

Use 320x240 for tutorial stills and classic media thumbnails only when it matches the available slot. The preset creates an exact 4:3 landscape frame; it does not certify compatibility with every template or service.

Keep the instructional action away from edges that a 4:3 crop may remove from a wider source. If a pointer, control, or label becomes ambiguous at 320x240, crop closer to the relevant interface region instead of shrinking the whole scene.

When preparing tutorial stills and classic media thumbnails, keep the instructional action away from edges likely to be cropped from wider sources. A full-frame crop can remove material outside 4:3.
