Best practices & tips
For the sharpest results, start with the highest-quality source image you have. If you need a specific file size, use the dedicated size targets; if you need exact dimensions, enter them directly. When exporting for the web, WEBP usually gives the smallest files at great quality, while PNG is best when you need transparency and JPG is ideal for photographs.
