Compression helps reduce clutter — in files and in photos. But overdoing it can:

  • Permanently erase image data
  • Introduce visual artifacts
  • Flatten your composition or make scenes look unnatural

When to be cautious with file compression:

  • Saving the same JPG repeatedly (each save adds more loss)
  • Exporting at very low quality settings
  • Compressing thumbnails from already-compressed files

Best practice: export your final edit at high quality, then compress for sharing separately.

When to be cautious with background compression:

  • Using extreme zoom where it distorts perspective
  • Compressing backgrounds that shouldn’t feel “close” (e.g., wide landscapes)
  • Trying to fake depth of field with focal length alone

Compression is a tool — not a goal. When used intentionally, it simplifies. When used blindly, it can backfire.
