What is Image Resizing?
Image resizing changes the pixel dimensions (width and height) of a digital photo or graphic. Whether you need exact dimensions for an online application or need to downscale a 24-megapixel camera shot for web display, resizing scales the pixel grid accurately.
Using bicubic interpolation and aspect ratio locking, our tool ensures your images do not stretch, skew, or pixelate. You can specify exact pixels, percentages, or select popular display presets for social media and document standards.
Resizing before publishing eliminates browser layout shifts (CLS) and ensures photos fit seamlessly into designated template frames.

? Frequently Asked Questions
Will resizing reduce the quality?
Scaling down an image typically preserves quality nicely. However, scaling an image up significantly (over 100%) can lead to a loss in sharpness or pixelation, depending on the original resolution.
Are my images secure?
Yes! The resizing process happens entirely in your browser using local resources. Your files are never uploaded to our servers, ensuring 100% privacy and security for your sensitive documents and photos.
How do I keep the image from getting squished?
Make sure the "Maintain aspect ratio" checkbox is checked when entering custom pixel dimensions. This automatically calculates the other dimension so your image stays proportional.
