Image creative specs per platform — aspect ratios (1:1, 9:16, 1.91:1), formats (JPG/PNG/WebP), 30MB max. Source from Creative Hub or upload.
Creative — images
Upload images in Campaign Creator's creative step (Express or Pro). Per-platform specs vary by aspect ratio and format. Common: 1080×1080 (1:1 square) + 1080×1920 (9:16 vertical) + 1200×628 (1.91:1 landscape). JPG / PNG / WebP, max 30 MB. Source from Creative Hub or direct upload.
Who is this for
Mediabuyers + creative producers preparing image assets for campaigns. Anyone uploading an image and seeing "wrong aspect ratio" error.
The 3 most-common aspect ratios
Multi-aspect campaigns: upload 2-3 sizes per ad to cover all placements. Wevion's Advantage+ Placements (Meta) auto-picks per placement when multiple sizes provided.
Per-platform specs

Upload paths
From Creative Hub
Recommended path. Assets already uploaded + tagged + optionally AI-generated:
- Campaign Creator creative step
- Click Choose from Creative Hub
- Filter by tag, type, folder
- 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:
- Campaign Creator creative step
- Drag-and-drop file OR click Upload
- 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

- 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
FAQ
What image formats and file size does Wevion accept?
Wevion accepts JPG, PNG, and WebP (plus GIF on Meta), with a general max of 30 MB, though per-platform limits vary — Google Display caps at 5 MB, TikTok at 50 MB, Snapchat at 32 MB, and Taboola at 5 MB. Upload from Creative Hub or drag-and-drop directly in the Campaign Creator creative step.
Which aspect ratios should I upload?
The three most common are 1:1 square (1080×1080) for feeds, 9:16 vertical (1080×1920) for Stories, Reels and TikTok, and 1.91:1 landscape (1200×628) for Meta Feed and Google Display. Upload 2-3 sizes per ad so Wevion includes them all and Meta's Advantage+ Placements picks the best per placement.
What happens if I upload only one image size?
Wevion can auto-crop a single source down to the required placements, but it can only crop down, not up. Upload at least 1080 pixels on the shortest side, since heavy cropping (for example 4K landscape to 9:16 vertical) loses content. For best quality, upload native sizes per aspect ratio.
Where do uploaded creatives go in Wevion?
Every image you drag-and-drop or upload in the Campaign Creator creative step is stored in Creative Hub automatically, tagged "campaign-direct-upload". You can also pick already uploaded, tagged, or AI-generated assets via "Choose from Creative Hub", where the ad uses a reference rather than duplicating the file. AI generation uses AI Credits.
