Output format

JPG, PNG and WebP keep their formats. HEIC and HEIF become JPG. PNG remains lossless.

PNG is saved without quality reduction. Dimension limits can still reduce its size.

Transparent areas become white in JPG files.

How should file size be controlled? Balanced qualityUse one visual quality level for every image. Target file sizeAim for a maximum size per image. Dimensions may shrink when needed.

{{ t('settings.qualityLevel', { value: quality }) }} Target size per image KB Limit image dimensionsImages already within the limit keep their dimensions.
