Thumbnail tool features
Precise controls for every thumbnail
TUMNAIL pairs aspect locking, multi-scale previews, and focal guides so each thumbnail stays sharp and legible wherever it appears.
Framing and preview
Locked ratios and focal overlays
Standard aspect ratio presets keep borders from distorting across video platforms. Pick a preset once and the frame holds its shape as you edit.
Multi-scale views
Check every size before publishing
Preview modes simulate mobile feed viewports and desktop search rows, so you can confirm a thumbnail reads clearly at each size.
Subject placement
Position the focal point
Precise focal overlay guides show where viewers' eyes land, helping you place faces and key elements in the strongest spot.
Output and inputs
Settings that shape the final file
Output fidelity
Adjust fidelity settings to balance sharpness and file weight for each destination.
Resolution options
Choose the output resolution that matches the platform where the thumbnail will appear.
Supported inputs
Work from common visual file types, bringing your source images straight into the frame.
