Image converter
Convert your images to the format and size you need.
Up to 20 MB per file · Up to 20 megapixels
Images are processed in your browser. Reducing the width preserves the aspect ratio.
JPG replaces transparency with white. GIF is converted to a still image of its first frame.
How to use
- Choose a PNG, JPG, WebP, GIF or BMP image up to 20 MB and 20 megapixels. File support depends on your browser.
- Choose PNG, JPG or WebP and a maximum width. Images are reduced proportionally and are not enlarged beyond their original size.
- Convert, check the dimensions and file size, then download. JPG and WebP support a quality setting.
Example
An 800 × 600 image becomes 400 × 300 when the maximum width is 400 px. Conversion does not always reduce file size; compare the result.
