Tips & Best Practices
Start with "Auto"
For most cases, the "Auto" compression level provides the best results. Only use "Lossy" if you need the absolute smallest file size and can tolerate some quality reduction.
Check Visuals After Lossy Compression
If your document contains important photos or detailed graphics, review the output of a "Lossy" compression to ensure the quality is still acceptable for your needs.
