Resize & Crop — FAQ
Will resizing reduce image quality?
Downscaling (making an image smaller) is essentially lossless when you use a good algorithm — our resizers use browser-native bicubic sampling. Upscaling (making it larger) always adds artifacts; for that, use the Image Upscaler which uses AI-based super-resolution.
What's the difference between resize and crop?
Resize changes the pixel dimensions of the whole image (everything shrinks or grows). Crop removes pixels from the edges to change the aspect ratio or composition without stretching what remains.
Can I resize a batch of images at once?
Yes — the Batch Image Resizer accepts unlimited files, applies the same dimensions to all, and lets you download them as a single ZIP.
