About Image Resizer
This tool resizes images in your browser using the Canvas API. Images are not uploaded to SindhTools.
When keeping proportions, the image is fitted within the requested width and height. Exact dimensions can stretch an image if the proportions do not match.
Resizing changes pixel dimensions; it does not guarantee a smaller file size. Review the output before using it.
Frequently asked questions
Which formats are supported?
JPG, PNG and WebP input are supported. Output can stay in the original format or be converted to JPG, PNG or WebP.
Are my images uploaded?
No. Image processing happens in your browser on your device.
Can I keep the original proportions?
Yes. Keep proportions is enabled by default. When both dimensions are entered, the image fits within that box without stretching.
Will resizing always reduce file size?
No. File size depends on the image, dimensions, format and encoding settings. Compare the result before downloading.
