Five common mistakes
- Converting in the wrong direction — going from lossy back to lossless doesn't recover the lost data.
- Re-encoding the same file twice — quality drops each pass.
- Wrong quality preset — aggressive for archival, conservative for web. Easy to mix up.
- Forgetting to verify the output — open it, check it looks right, before committing.
- Stripping metadata you needed — copyright, color profile, timestamps. Worth knowing which ones to keep.
