Upload paths

From Creative Hub

Recommended path. Assets already uploaded + tagged + optionally AI-generated:

  1. Campaign Creator creative step

  2. Click Choose from Creative Hub

  3. Filter by tag, type, folder

  4. Pick file → ad uses reference (not duplicated)

See cc-116 use Creative Hub in Campaign Creator.

Direct upload

For one-off creatives not yet in Creative Hub:

  1. Campaign Creator creative step

  2. Drag-and-drop file OR click Upload

  3. Wevion stores in Creative Hub automatically (tagged as "campaign-direct-upload")

AI generation

In Creative Hub: Generate → Image with text prompt. Output lands in Hub. Then pick in Campaign Creator. Uses AI Credits.

Multi-aspect upload pattern

For a single ad to serve all placements (Feed + Stories + Reels):

  • Upload 1:1 (Feed)

  • Upload 9:16 (Stories + Reels)

  • Optional 4:5 for vertical Feed-optimized

  • Wevion includes all in the ad spec; Meta picks per placement

This is the most-effective single-ad pattern (covers Meta's full inventory).

Auto-cropping (when single source provided)

If you upload only one size (e.g. 4K landscape), Wevion can auto-crop down to required placements. But quality matters:

  • Upload at least 1080+ on shortest side

  • Wevion can crop down, not up

  • Heavy cropping (4K landscape → 9:16 vertical) loses content

For best quality: upload native sizes per aspect.

Text on image (best practices)

  • Visual hierarchy matters more than text quantity

  • Logo small, legible: 100-150px on a 1080×1080 canvas

  • Headline overlay: 4-6 words, bold sans-serif

  • CTA visible: button-like or arrow design

  • Brand colors: consistent with your brand kit

  • Mobile-first design: most ad views are on phone

Image quality

  • High-res source: 4K originals downscale beautifully; low-res upscaled looks bad

  • JPG quality 80-95%: balance file size + quality

  • PNG for transparent backgrounds (logos, badges)

  • WebP modern format: smaller file size, supported by all major ad platforms

In Wevion's launchers

Express creative step

  • One creative slot per ad

  • Drag-and-drop OR pick from Hub OR AI-generate

  • Live preview on right

Pro mode

  • Per-ad creative config

  • Multi-aspect upload (all sizes in one ad)

  • Crop tool for fine-tuning

Bulk Launch

  • Per-row creative reference (Hub asset ID OR URL to uploaded file)

  • Bulk-upload creatives to Hub first, then reference in rows

Common issues

  • "Aspect ratio rejected": platform requires specific ratio (1:1 / 9:16 / 1.91:1 etc.). Re-crop or upload native size.

  • "File too large": exceed per-platform limit. Compress (reduce dimensions or quality) or split into multiple ads.

  • "Image blurry after upload": source was lower res than required. Re-upload at higher res.

  • "Color shift after upload": platform converts to sRGB. Export as sRGB JPG to avoid surprise.

  • "Logo cut off in Stories placement": 9:16 vertical has safe zones (top 200px + bottom 250px reserved for UI). Place logo in middle 60% vertical zone.

  • "Auto-crop crops wrong area": provide native aspect or specify crop region in Pro mode.

Best practices

Test creative variations

A/B test 3-5 creative variations per adset. Even small changes (different headline overlay, different background color) can drive 30%+ CTR differences.

Refresh quarterly

Creative fatigue is real (cc-112 saturation AI). Refresh creative every 30-60 days for high-spend campaigns.

Match aesthetic to platform

  • Instagram Feed: polished, aspirational

  • Stories: candid, vertical-first, sound-on

  • TikTok: native-feeling, low-production

  • Google Display: clear value prop, brand-recognizable
