Frequently Asked Questions
If I enter both width and height, will my image get stretched?
No — by default the tool fits your image inside the box you specify while keeping its original aspect ratio, so it won’t be stretched or distorted even if your numbers don’t match the original proportions.
Can I resize to a larger size than my original image?
Yes — enlarging is allowed, though upscaling a small image significantly can make it look softer since no new detail is being created.
What happens if I only enter a width and leave height blank?
The height is calculated automatically to keep the original aspect ratio.
Does resizing change the file format?
No — the output keeps your original image format.
Can I resize multiple images to the same dimensions at once?
Not with this tool — use Bulk Image Resizer for resizing many images to identical dimensions in one pass.
