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.
