Why use a dedicated TikTok tool?

General purpose tools often fail when you need to meet strict, platform-specific requirements. By using our pre-configured engine for TikTok, you ensure your file meets exact dimensions, quality limits, and format specifications automatically.

Zero-Upload Privacy: Unlike other cloud converters, FileCircle utilizes WebAssembly and HTML5 Canvas to process your files directly inside your browser.

Best of all, because FileCircle relies entirely on your browser's local processing power, your files are never uploaded to a cloud server. You get enterprise-grade optimization with 100% absolute privacy.

Frequently Asked Questions

What is the best resolution for TikTok images?
TikTok favors full-screen vertical content. You should aim for 1080 pixels wide by 1920 pixels tall, which is a 9:16 aspect ratio.
How do I avoid TikTok UI elements blocking my photo?
The TikTok interface is cluttered. Keep important text and faces away from the bottom 20% (where captions go) and the right edge (where the like and share buttons live).
Can I convert these photos into a PDF later?
Yes, if you want to bundle your vertical slideshow images into a shareable document, you can process them through our Images to PDF converter.
