Show outcomes, not noise. Use clean 4:3 visuals, avoid cluttered collages, and keep brand type/colors consistent. Pick thumbnails with clear hierarchy and minimal text; export sharp JPG/PNG and front-load your strongest work.

Best Practices

FAQ

What image size should I use for Upwork portfolios?

1000×750 px at 4:3 is the recommended size. Upwork supports anywhere from 400×300 up to 4000×4000, max 10 MB per image.

How do I make Upwork portfolio thumbnails stand out?

Use clear visual hierarchy, minimal text, high contrast, and avoid thin details that compress poorly. Lead with the result, not the process.

Can I add video case studies to Upwork?

Yes, via YouTube links. Keep them concise (under 60 seconds), lead with outcomes, and include captions for sound-off viewing.

What's the best image format for Upwork portfolios?

PNG for screenshots, UI work, and anything with text; JPG for photography and mockups. Avoid WebP — not all browsers render it consistently in portfolios.

How many portfolio items should I upload?

6–10 strong examples beats 20 mediocre ones. Upwork reviewers skim quickly, so front-load your best work in the first three slots.

What's the agency profile banner size?

3200×320 px at 10:1. The banner is wide and shallow, so center your logo and keep any text in the middle third.
