Image Resizer
Resize JPG, PNG and WebP images by width, height, percentage or maximum dimension while preserving aspect ratio and processing locally.
What this tool solves
Resize images by width, height, maximum dimension or percentage, preserve aspect ratio and download locally.
Input: a local JPG, PNG or WebP image and the required dimensions.
Output: a resized image with the selected width and height.
How to use it
- Add an image and note its original pixel dimensions.
- Set width, height, percentage or maximum dimension; keep aspect ratio locked unless distortion is intentional.
- Preview the result and download it, then confirm text and fine details remain readable.
Common use cases
- Prepare profile photos and website assets
- Reduce oversized phone photos before upload
- Create consistent dimensions for product or article images
Privacy, accuracy and limits
Upscaling cannot restore detail that was not in the source. Very large images can use significant memory on phones.
WebToolMint keeps this workflow local in the browser where the feature allows it. Network-dependent tools are labelled separately. Keep originals and independently verify results that affect legal, financial, medical or business decisions.
Frequently asked questions
How do I resize without stretching the image?
Keep the aspect-ratio option enabled and change only one dimension, or use a maximum-dimension mode.
Does resizing reduce file size?
Usually yes when pixel dimensions are reduced, but final size also depends on format and quality.
Can I enlarge a small image?
Yes, but enlargement interpolates pixels; it does not create the missing detail of a higher-resolution source.
