Frequently Asked Questions
What image formats are supported?
This tool supports JPEG, PNG, WebP, and GIF images. You can also convert between formats when downloading.
Is my image uploaded to a server?
No. All image processing happens entirely in your browser using the Canvas API. Your images never leave your device.
What is the maximum image size?
There is no hard limit, but very large images (over 50 MP) may be slow to process depending on your device.
Can I maintain the aspect ratio?
Yes. The aspect ratio lock is enabled by default. When you change the width, the height is automatically calculated to maintain proportions.
About Image Resizing
Resizing images is essential for web optimization, social media, email, and print. Large images slow down websites and consume bandwidth. This tool lets you resize any image to exact pixel dimensions while maintaining quality, all without uploading your files to a server.
