Compress Image for TikTok
Compress images for TikTok in the vertical 9:16 format with the best balance of quality and speed.
TikTok's photo mode (slideshows) is designed around full-screen vertical media. Images are shown edge-to-edge on a 9:16 phone screen. Resizing to 1080 × 1920 and encoding as WebP keeps the file tiny while the on-screen result looks identical.

Compression strategy
- TikTok photo slideshows display best at 1080 × 1920 (9:16).
- WebP typically beats JPEG on size at equal quality for photographic content.
- We keep PNG transparency when present — WebP supports alpha, JPEG does not.
- No upscaling: smaller source images keep their original resolution.
FAQ
What image resolution does TikTok recommend?
1080 × 1920 for the 9:16 vertical format used by TikTok photos and slideshows.
Can TikTok images be horizontal?
Yes, but they display letterboxed on a vertical phone screen. We keep your aspect ratio when it deviates from 9:16 instead of cropping the photo.
Does TikTok compress images?
Like every social platform it processes content server-side. The goal here is to upload a file so close to TikTok's display spec that re-encoding has little to chew on.
Are my TikTok images private?
Yes. Processing happens entirely in your browser via the Canvas API — nothing is transmitted.
