Frequently Asked Questions

Will resizing reduce image quality?

Downscaling generally preserves quality well. Upscaling beyond the original size may introduce some softness. We use high-quality bicubic resampling for the best results.

What presets are available?

1080p (1920x1080), 720p (1280x720), Instagram square (1080x1080), Twitter card (1200x675), Thumbnail (320x240), and percentage-based options (50%, 25%).

Can I resize without maintaining aspect ratio?

Yes. Click the lock icon between width and height fields to toggle aspect ratio lock on or off.
