Images

Formats and limitations

Convert changes an image’s format. Compress changes its file size; resize changes its pixel dimensions. Crop keeps a smaller part of the picture.

For website photos, resize to the dimensions you need, then compare JPG and WebP output. For an iPhone photo that another app cannot open, use HEIC to JPG.

JPG replaces transparency with a background color. GIF converters keep only the first frame. HEIC and AVIF support depends on the file and browser. Background removal downloads a large model and may need edge corrections.

Metadata removal cleans supported fields; it does not hide details visible in a picture. File, dimension, and batch limits are shown before selection in each tool.
