What's the best AI image size for Facebook Marketplace?

Facebook Marketplace performs best with square 1080x1080px images (minimum 500x500px). FluxNote's 'Marketplace' template auto-generates clean product shots with neutral backgrounds that meet these specs.

How to make AI images look less artificial on Facebook?

Blend AI elements with real photos using FluxNote's 'Photo Composite' mode. Add 5% film grain, slight lens blur at edges, and natural lighting prompts like 'soft window light' to avoid the 'AI look' that gets penalized.

Can I use AI images for Facebook profile pictures?

Yes, but keep under 170x170px. Avoid full AI faces - Meta may flag them. Instead, use FluxNote's 'Illustrated Portrait' style for policy-compliant PFPs that still stand out.

What file format is best for Facebook AI images?

JPG for photos (85% quality), PNG for graphics with text. For animated content, MP4 at 30fps (under 4MB) works best. FluxNote auto-selects the optimal format based on your content type.

How many AI images should I post per week on Facebook?

3-5 high-quality AI posts weekly is ideal. Beyond that, engagement drops 7% per additional post. Use FluxNote's content calendar to space out variations (e.g., product shots, infographics, testimonials).
