FAQ

What size does this YouTube Thumbnail preset export?

This preset exports 3840 x 2160 pixels (3840x2160). Fill crops the image without stretching it. Fit keeps the full picture and adds a colored border where needed. The format is fixed by the preset.

What should I check for this YouTube Thumbnail export?

This preset follows the current recommendation for regular video thumbnails, not Shorts or podcast artwork. Check YouTube's device-specific file-size limit; this preset does not enforce it. A larger export cannot restore detail missing from a small original.

Should I export a YouTube Thumbnail as JPG or PNG?

This preset exports JPG, which does not keep transparency. In Fill, transparent areas become white; in Fit, you choose the background color. For transparent artwork or a different output format, use a suitable PNG preset or another editor.

Is this YouTube Thumbnail resizer free and private?

Resizing is free with no sign-up. FitShift's image code processes the selected file in your browser, without an upload. The website still makes ordinary hosting requests; see the privacy page for that distinction.
