Compare quality, transparency, convenience and file size to choose the right format.

When this task helps
WebP often gives a good balance of quality and size for websites, while JPG remains useful for photographs and broad compatibility.
Worked example
A 2400-pixel image used in a 600-pixel card may remain large even as WebP. Resize for the real display size and compare the export with the source.
What to check before starting
If you need transparency, consider WebP or PNG. For regular photos, compare results visually and keep the smallest file that still looks good.
Choosing the settings
Try moderate quality and inspect texture, small text and transparency. Keep PNG or JPEG if the destination rejects WebP. Choose based on actual output size rather than extension alone.
Limits that affect the result
WebP is not smaller for every image. Do not assume this converter preserves animation or every source metadata field.
Mistake to avoid
Do not convert a small, heavily compressed image expecting quality to return. Conversion changes the format; it does not recreate lost detail.
Illustrative example: size and quality depend on the source file.
