Files can carry more information than the content you immediately see. This guide explains the practical details so you can choose what to keep, remove or verify before sharing.
Compression targets data size
Image compression reduces the amount of data required to store an image. Lossy formats such as JPEG and WebP can trade some visual fidelity for smaller files. PNG typically uses lossless compression.
Metadata removal targets extra information
Metadata cleaning focuses on information associated with the file rather than the visual pixels. A file can be small and still contain metadata, or large and contain almost none.
One re-encode can do both
When you decode an image and export a fresh JPEG or WebP at a selected quality, the same operation can avoid copying metadata and reduce file size. That is efficient, but repeated lossy re-encoding can degrade quality.
Work from the best source
Use your original or highest-quality master as the source for the final web copy. Avoid repeatedly compressing already compressed versions across multiple tools.
Use the relevant BeOutMeta tool on a copy of your file, then review the result before publishing or sending it.
