Question 1

What happens to the aspect ratio?

Accepted Answer

When 'Maintain aspect ratio' is checked (the default), images are scaled to fit within the specified width and height without distortion. The largest dimension is matched and the other is adjusted proportionally. Uncheck it to stretch images to the exact dimensions.

Question 2

Does resizing affect image quality?

Accepted Answer

Downscaling (making images smaller) generally preserves quality well. Upscaling (making images larger) may introduce blurriness since the browser interpolates new pixels. The quality slider controls the output encoding quality for JPEG and WebP formats.

Question 3

How many images can I resize at once?

Accepted Answer

You can upload up to 50 images at a time, each up to 50 MB. All resized images are packaged into a single ZIP file for easy download.
