What Image Resizer helps you do
Change an image to exact pixel dimensions without uploading it to Haivix. The tool reads the original width and height, keeps the aspect ratio locked by default, previews the resized result, and produces a downloadable copy.
Files are processed entirely in your browser. Nothing is uploaded to Haivix servers.
How to use Image Resizer
- Add the source image and leave aspect ratio locked unless you intentionally need a different shape.
- Enter the required width or height, then preview the resized result.
- Download the resized image; crop first if you need exact width and height with a different aspect ratio.
What you can do with Image Resizer
- Read and display the source image dimensions.
- Set an exact width or height in pixels.
- Keep proportions synchronized with aspect-ratio lock.
- Preview and download the resized image from the browser.
Example: prepare a consistent article thumbnail
Add the source image, leave aspect ratio locked, and enter the required width. Review the calculated height and preview the resized result before downloading.
If the publishing system needs an exact width and height with a different shape, crop the source to that aspect ratio first. Turning off the lock and forcing both dimensions can stretch faces, logos, and circles.
What to know before you start
- Upscaling creates more pixels but cannot restore detail missing from a small source.
- The output keeps the source format when the browser supports it, while the download filename is standardized.
- Resizing changes dimensions; use Image Compressor when file weight remains too high after resizing.
Frequently Asked Questions
Yes. Aspect ratio stays locked by default so changing width updates height proportionally unless you unlock it intentionally.
JPG, PNG, and WebP are supported in most browsers. Output format follows the source unless the tool offers a conversion option.
