About This Tool
ToolsFaction Image Resizer gives you precise control over image dimensions without requiring desktop editing software. Resize JPG, PNG and WebP files by exact width and height or scale them by percentage. Aspect-ratio locking helps prevent accidental distortion, while quick presets make common dimensions faster to apply.nnYou can export the resized result as JPG, PNG or WebP and adjust quality for compatible formats. The preview, output dimensions, scale percentage and resulting file size make it easy to check the result before downloading.
How to Use
- Drop a JPG, PNG or WebP image into the tool or choose a file from your device.
- Choose Exact Pixels or Percentage. Enter your target dimensions or scale value.
- Keep aspect ratio locked when you want to avoid stretching, or use one of the quick dimension presets.
- Choose an output format and quality, resize the image, review the result and download the finished file.
Example
Upload a 4000 × 3000 photo, keep the aspect ratio locked and set the width to 1920 pixels. The height is calculated automatically before the resized image is exported.
Frequently Asked Questions
Which image formats can I resize?
The tool accepts JPG, PNG and WebP images and can export JPG, PNG or WebP in supported modern browsers.
Can I resize an image by percentage?
Yes. Switch to Percentage mode and enter a scale value to resize relative to the original dimensions.
What does Lock aspect ratio do?
It keeps the original width-to-height proportion when you change one dimension, helping prevent stretched or squashed images.
Can I resize to exact pixel dimensions?
Yes. Exact Pixels mode lets you enter specific width and height values, and you can disable aspect-ratio locking when a fixed dimension pair is required.
Does resizing change file size?
Usually. Smaller pixel dimensions often reduce file size, while the selected output format and quality can also significantly affect the final size.
What happens to transparency when exporting as JPG?
JPG does not support transparency, so transparent areas are filled with white for JPG output.
Are images processed locally?
Image resizing is designed to run directly in your browser using browser image and canvas capabilities.
