WhatsApp profile photos are cropped to a square at 640x640 pixels, and images sent in chats are compressed by WhatsApp if they exceed certain dimensions. Pre-resizing your images ensures they arrive at maximum quality without being further compressed by the platform.

常见问题解答

Can I resize an image to exact pixel dimensions?
Yes. Enter the exact width and height in the input fields. Toggle Lock Aspect Ratio to maintain proportions, or disable it to stretch freely to any dimensions.
What is the maximum resolution I can resize to?
The browser Canvas API can handle very large images. Resizing to 8000x8000px or above is supported on most modern devices, though it may take a few seconds for very large outputs.
Does resizing increase image file size?
Upscaling can increase file size significantly because you are creating more pixels. For smaller files after upscaling, run the result through our Compress Image tool.
Can I resize an image by percentage instead of pixels?
Yes. Switch from pixels to percentage mode using the toggle. Enter 50 to reduce to half size, or 200 to double the dimensions.
