Image Resizing Tips
Short comparisons and tips to help you choose the right option faster.
Pixels vs percentage resizing
Resize by pixels when you know the exact output dimensions you need. Resize by percentage when you want a proportional reduction or enlargement.
When to lock aspect ratio
Keep aspect ratio locked for most web images to avoid distortion. Unlock it only when you intentionally need a different crop or stretched canvas shape.
How to Use
Follow these quick steps to get the result you need.
Upload an image to load its original dimensions and preview.
Choose whether to resize by pixels or percentage, then edit width or height while optionally locking the aspect ratio.
