Frequently Asked Questions
Resizing changes the actual dimensions of an image in pixels, while compression reduces the file size by removing some data (which may affect quality). For best results, you should both resize to appropriate dimensions and apply optimal compression.
While some quality loss is inevitable when reducing image size, you can minimize it by: 1) Using high-quality originals, 2) Resizing proportionally, 3) Choosing the right file format, 4) Using professional tools with good algorithms, and 5) Avoiding multiple resizes of the same image.
For photographs: JPEG is usually best. For images with transparency or simple graphics: PNG is better. For modern web use: WebP offers excellent compression. For print documents: TIFF or high-quality JPEG may be preferred.
Consider the final display size. For websites, check your theme's recommended image sizes. For documents, think about the printed size and resolution (usually 300dpi for print). When in doubt, our image resizer tool can help you choose appropriate dimensions.
