Frequently asked questions
What ad sizes are available?
The tool includes presets for Meta/Instagram (1080×1080 square, 1080×1350 portrait, 1080×1920 story), Facebook/LinkedIn landscape (1200×628), Google Display (728×90, 300×250, 160×600), Twitter/X (1600×900), and YouTube thumbnails (1280×720).
What is the difference between Cover and Contain fit modes?
Cover fills the entire target area by scaling the image up and cropping any overflow — no empty space but some parts may be cut off. Contain scales the image down so it fits entirely within the target area, adding white padding to fill any remaining space.
Can I resize to a custom size?
Currently the tool offers the most common ad platform presets. For custom dimensions, use the preset closest to your target and then fine-tune in your design tool.
Does resizing affect image quality?
Upscaling a small image to a large preset may introduce softness. For best results, start with the highest-resolution source image available. Downscaling preserves quality well.
