> Quick answer: TikTok recommends 1080x1920px for vertical image ads. If your image falls short, AI Upscale in Coinis Revise gets it to spec in one click. No design tools required.
A blurry TikTok ad kills credibility before anyone reads the copy. Low-res images stretch badly on high-resolution mobile screens and signal to viewers that your brand isn't serious. Fix the problem fast with AI upscaling.
Why Low-Res Images Hurt TikTok Ads
TikTok renders ads on bright, high-density phone screens. A small or heavily compressed image stretched to full screen looks pixelated immediately. Lower visual quality drops viewer trust. Lower trust drops click-through rate. Blurry or unclear creatives can also fail TikTok's automated quality review, delaying your campaign launch.
TikTok Image Ad Resolution Requirements
Standard feed image specs
Per TikTok Ads Manager guidance, the recommended resolution for vertical image ads is 1080 x 1920 pixels, which is Full HD at a 9:16 aspect ratio. The platform minimum is 540 x 960 pixels. Most advertisers target at least 720 x 1280 pixels for reliable sharpness across different devices and screen sizes.
Keep your image under 100 MB. In practice, a well-optimized JPEG or PNG at 1080x1920px comes in well under that limit.
Aspect ratios and sizing
TikTok supports three aspect ratios for image ads: 9:16 (vertical), 1:1 (square), and 16:9 (horizontal). Vertical fills the full phone screen and performs best for TikTok-native placements. Square suits some multi-placement setups. Horizontal is rare for in-feed TikTok ads.
TikTok updates its ad specs regularly. Always confirm the latest requirements at ads.tiktok.com before launching a campaign.
How AI Upscaling Works
Neural networks vs. simple resizing
Basic resizing just stretches existing pixels. It blurs edges and makes images look soft. AI upscaling works differently. Premium AI models trained on millions of images predict and add new pixels where they belong. The result is sharper edges, cleaner detail, and a natural look at higher resolution. Not a stretched version of the original.
When upscaling helps (and when it doesn't)
AI upscaling works best on product photos, brand imagery, and archive shots with decent original quality. It also recovers UGC and older campaign assets that predate HD standards. It cannot invent detail that was never captured. A heavily corrupted or aggressively compressed source image may still look soft after processing. Always start with the highest-quality version of the file you can find.
Step-by-Step: Upscale Your Low-Res Image for TikTok
Prepare your source image
Export the best available version of your image. A lightly compressed PNG at 400px will yield better upscaling results than a heavily compressed JPEG at the same size. If the image has unwanted text or watermarks, AI Erase in Coinis Revise can clean those up before or after upscaling.
Upscale using Coinis Revise AI Upscale
- Open Coinis Revise.
- Upload your low-res image.
- Select AI Upscale from the editing toolbar.
- Choose your target resolution. Aim for 1080x1920px for vertical TikTok placements.
- Apply the upscale. The premium AI models restore detail and sharpen edges.
- Download the finished file.
The whole process takes under a minute.
Verify resolution before launching
Check the downloaded file's dimensions before uploading to TikTok Ads Manager. On Mac, use Get Info. On Windows, right-click and open Properties. Target 1080x1920px for vertical placements. Minimum 540x960px if you're working with tight file constraints. If the image still looks soft on inspection, run AI Upscale once more from the Revise editor.

Frequently Asked Questions
What is the minimum image resolution for TikTok ads?
TikTok's minimum image ad resolution is 540 x 960 pixels. The practical recommended minimum for reliable clarity across devices is 720 x 1280 pixels, and the ideal target for full-screen vertical ads is 1080 x 1920 pixels.
Will AI upscaling make my blurry image look completely sharp?
AI upscaling significantly improves sharpness and detail by intelligently adding new pixels, but it cannot recover detail that was never in the original file. Start with the highest-quality source image you have for the best result.
Can I use Coinis Revise to upscale images for platforms other than TikTok?
Yes. Coinis Revise AI Upscale works on any ad image regardless of platform. You can upscale once and then use Smart Resize to export the same image at the correct dimensions for TikTok, Meta, Google Display, and other channels.
