About Resize Image
Resize any image to exact pixel dimensions or by percentage –entirely in your browser with zero data leaving your device. This tool supports JPEG, PNG, and WebP inputs and lets you lock the aspect ratio to prevent distortion. Ideal for resizing photos for social media profiles, blog posts, email headers, or product listings. You can specify width and height independently or constrain proportionally. Output quality and format are configurable. Because all operations run client-side via the HTML5 Canvas API and advanced browser APIs, your images remain completely private throughout the process. Batch resizing for multiple files is also available.
Frequently Asked Questions
Will resizing reduce image quality?
Downscaling generally preserves quality well. Upscaling may introduce blurriness since no new pixel data is created.
Can I resize to a percentage instead of pixels?
Yes. Switch to percentage mode and enter a value such as 50 % to halve both dimensions.
Does the tool maintain aspect ratio?
By default, aspect ratio is locked. You can unlock it to set width and height independently.
