Compare quality, transparency, convenience and file size to choose the right format.
When this guide is useful
WebP often gives a good balance of quality and size for websites, while JPG remains useful for photographs and broad compatibility.
Think about where the file will be used. Messaging, social media, websites, presentations and archiving can require different sizes and formats.
How to decide without overcomplicating it
If you need transparency, consider WebP or PNG. For regular photos, compare results visually and keep the smallest file that still looks good.
Always start with a copy of the original file. That gives you a reference and lets you try another setting without losing the best-quality source.
How to check whether the result is good
Make a first attempt with moderate settings. Then review the full result, especially areas with small text, faces, music, transitions or fine detail.

Common mistakes to avoid
Do not convert a small, heavily compressed image expecting quality to return. Conversion changes the format; it does not recreate lost detail.
