Frequently asked questions
What's the difference between cover and contain?
Cover scales the image up to fill the target size and crops the overflow centered (best for social covers); contain scales it down so the whole image fits, padding the sides with your chosen color (nothing lost).
Will resizing blur my image?
Scaling down won't; scaling far beyond the original resolution loses sharpness — a physical limit of any resizer. Start from a source at least as large as the target when possible.
Is batch supported?
It currently does one high-quality image at a time. Resizing several is quick one by one — fully local, with no count limit.
