Supported Formats
The tool supports the most popular image formats:
- JPEG - a lossy compression format, ideal for photographs
- PNG - a lossless format with transparency support
- WebP - a modern format offering better compression and smaller file sizes
Image Resizing
When resizing an image, you can:
- preserve the image aspect ratio - the image will be scaled while maintaining its original proportions,
- set a custom width and height in pixels or percentages,
- reduce or enlarge the image size.
If you disable aspect ratio preservation, three resize modes are available:
- Stretch - the image is resized to the specified dimensions, which may cause distortion,
- Fit (with margins) - the image is scaled proportionally, and the remaining space is filled with a selected background color,
- Crop - the image is scaled to fill the entire area, and excess parts are cropped.
Dimension Units
You can choose the units used to define image dimensions:
- Pixels - set exact dimensions in pixels,
- Percentages - dimensions defined as a percentage of the original size (e.g. 50% means half of the original size).
Image Quality
For JPEG and WebP formats, you can adjust the compression quality. Lower quality results in smaller file sizes but may introduce visible artifacts.
Select the appropriate settings based on the intended use of the image. For web publishing, WebP or JPEG with a quality of 80-90% is recommended. For graphics that require transparency, PNG is the best choice.
