Frequently Asked Questions

How does lossless compression work?

We remove non-essential metadata and apply format-specific optimizations.

Can a JPG be compressed losslessly?

We can remove metadata and re-encode at maximum quality. Pixels may be re-encoded but remain visually identical for practical purposes.

Why is there no quality slider?

Lossless mode prioritizes perfect appearance, so we optimize automatically.
