Resize Image
Change image dimensions with precise control
What is image resizing?
Resize Image changes the dimensions of your image to any width and height you specify. Use it to prepare images for social media posts, email attachments, web pages, or print — without needing image editing software.
Processing runs entirely in your browser. Your image is never uploaded anywhere. You can resize by exact pixel dimensions, by percentage, or constrain proportions to avoid distortion.

Frequently asked questions
Can I resize an image without distorting it?
Yes. Enable the 'Lock aspect ratio' option and the tool will automatically adjust the height when you enter a width (or vice versa), maintaining the original proportions.
What image formats are supported?
The resize tool supports JPG, PNG, WebP, GIF, BMP, and most other common image formats. The output format matches the input unless you use the Convert Image tool to change it.
Does resizing reduce image quality?
Upscaling (making an image larger) always reduces sharpness since new pixels must be interpolated. Downscaling (making it smaller) generally looks sharp. For best results, avoid upscaling beyond the original resolution.
Is there a maximum file size?
The tool handles images up to 50 MB. Very large images may take a moment to process in the browser.
