TikTok Ads Image & Video Sizes: The Complete 2025 Guide
TikTok is unforgiving with creative specs. Wrong size, wrong file weight — and your ad won't deliver. Here's everything you need.
TikTok ads are almost exclusively vertical. The platform was built for 9:16 full-screen content and everything else gets cropped, letterboxed, or simply rejected. If you're coming from Facebook advertising, the most important shift is: think vertical first.
TikTok also has strict file size limits — images must be under 500KB. This is much tighter than Meta's 30MB limit and means you need to compress images properly before uploading.
Quick Reference: All TikTok Ad Sizes
500KB limit: TikTok's image file size limit is much stricter than other platforms. A standard 1080×1920 JPG from a camera or Photoshop will typically be 2–5MB — you must compress it before uploading. MetaClean handles this automatically.
TikTok In-Feed Ads
In-Feed ads appear between organic content as users scroll. They blend into the For You page experience and are the most common format for performance advertisers.
Safe Zone: What Gets Covered by TikTok's UI
TikTok overlays its UI on top of your creative. If you put important content (text, faces, products) in these areas, they'll be covered:
Keep your product, face, and any text within the safe zone: roughly center 900×1640px of the 1080×1920 frame.
Why TikTok Compresses Your Images
TikTok recompresses every image you upload. If you upload at exactly 500KB, TikTok will compress it further for delivery — so you want to start with the highest quality possible within the limit.
The best approach: export your creative at high quality, then use a tool to reduce to under 500KB while maintaining visual quality. MetaClean does this automatically — it compresses to the platform limit without visible quality loss.
MetaClean auto-compresses to 500KB when you select TikTok as the platform — no manual compression needed.

What is the best image size for TikTok ads?
1080×1920px (9:16 vertical) is the recommended size for all TikTok ad placements. It fills the full screen and delivers the best visual impact. Always design for vertical mobile viewing first.
What file size limit does TikTok have for images?
TikTok limits image ads to 500KB. This is significantly stricter than Meta (30MB) or Google (5MB). You must compress your images before uploading — a standard camera JPG at 1080×1920 will be 3-5MB and will be rejected.
Can I use a square image for TikTok ads?
Yes — TikTok supports 1:1 (1080×1080px) and 16:9 (1920×1080px) for In-Feed ads, but 9:16 vertical performs significantly better. Vertical content feels native to the platform; square and landscape formats feel like imported ads.
What is a Spark Ad on TikTok?
Spark Ads let you boost existing organic TikTok posts as ads. Since you're using an existing post, the size is whatever the original content was. This format often outperforms standard In-Feed ads because it looks completely native.
Do TikTok ads need metadata removed?
Yes — as with all ad platforms, stripping EXIF metadata from images before uploading is best practice. It reduces file size slightly (helping with the 500KB limit) and removes location/device data that could trigger content filters.
Stop resizing manually.
Strip metadata and resize to every ad format automatically.
