Many platforms have specific size requirements for images, such as social media profiles, cover photos, or product listings on e-commerce sites.
Create a uniform look by ensuring all your images have consistent dimensions, especially important for galleries, portfolios, and product catalogs.

Reducing the size of an image generally doesn't affect its quality, while enlarging an image beyond its original dimensions may result in some quality loss. Our resize tool uses advanced algorithms to minimize quality loss during both reduction and enlargement.
The aspect ratio is the proportion between width and height. When you maintain the aspect ratio, the image will be resized proportionally without stretching or squishing. For example, if you change the width, the height will automatically adjust to keep the same proportions.
Our resize tool supports all major image formats including JPEG, PNG, GIF, BMP, WEBP, and TIFF. The output format will match the input format unless you also use our format conversion tool.
Free users can resize images up to 15MB each, with a maximum of 10 files per session. Premium users enjoy higher limits with files up to 50MB and unlimited batch processing.
