Frequently Asked Questions

What dimensions should I use for social media images?

Common sizes: Instagram post 1080x1080, Facebook cover 820x312, Twitter header 1500x500, LinkedIn banner 1584x396. Our tool includes presets for all major platforms.

Will resizing reduce image quality?

Enlarging images may reduce quality since it requires creating new pixels. Reducing size generally maintains or improves sharpness. For best results, start with the largest original image available.

Can I resize without changing the aspect ratio?

Yes, enable 'Maintain Aspect Ratio' to automatically calculate one dimension when you change the other. This prevents your images from being stretched or distorted.
