- Choose "Percentage" or "Pixels," then set the values (aspect ratio can be locked automatically).
- Click "Resize images" and download the result.
Frequently asked questions
Will resizing distort my image's proportions?
Only if you want it to — keep "Keep aspect ratio" checked when resizing by pixels and the tool calculates the matching height or width automatically so nothing looks stretched.
Can I resize several images to the same dimensions in one go?
Yes, add multiple images before resizing and the same settings are applied to every file in the batch.
Does resizing reduce file size too?
Generally yes — fewer pixels means a smaller file, though for a specific KB target, pair this with the Compress to Target Size tool instead.
