9:16 preview
Only crop photos you are allowed to use, of adults who consented. “Use as reference” keeps the image in your browser’s studio draft; it is uploaded only if you later generate a video. If it does not appear, download the JPEG and upload it in the studio.
What is the 9:16 aspect ratio?
The 9:16 aspect ratio describes a vertical frame that is 9 units wide for every 16 units tall, the shape of a phone screen held upright. It is the native format of TikTok, Instagram Reels and Stories, YouTube Shorts and Snapchat, and it is the format SpicyFrame renders every AI video in. A 9:16 image is exactly the 16:9 widescreen frame turned on its side, so 1920×1080 becomes 1080×1920.
Cropping a photo to 9:16 before you use it matters more than it seems. Social apps and image-to-video models that receive a landscape or square photo either add bars, zoom into the centre or invent the missing parts of the scene. Choosing the crop yourself keeps the face, the outfit and the composition you want inside the frame.
9:16 resolution: which size to export
Every 9:16 resolution keeps the same shape; only the pixel count changes. 1080×1920 (Full HD vertical) is the standard for social video and the safest choice for uploads. 720×1280 (HD) is lighter and matches SpicyFrame’s High 720p output. 1440×2560 (QHD) is what Meta lists for Reels ads, and 2160×3840 is vertical 4K. To check that a size is 9:16, divide the height by the width: the result is 1.777…
This tool exports at up to 1080 pixels wide for 9:16, 4:5 and 1:1, and 1920 wide for 16:9, without upscaling: if your crop contains fewer pixels, the file keeps the original detail rather than inventing it.
Private by design
The photo never leaves your device: it is decoded and cropped with the canvas of your browser, and nothing is uploaded to SpicyFrame’s servers. “Use as reference in SpicyFrame” stores the cropped image in your browser’s draft and opens the studio, where it appears as @Image 1 (or the next free slot). Only upload photos you are allowed to use, of adults who consented. Read our vertical AI video guide and the best photos for AI video checklist before you animate it.

Frequently asked questions
Is 1080×1920 the same as 9:16?
Yes. 1080 divided by 9 is 120, and 1920 divided by 16 is 120, so 1080×1920 is exactly 9:16. So are 720×1280, 1440×2560 and 2160×3840.
Is my photo uploaded when I crop it?
No. Cropping happens in your browser with the HTML canvas. The image is only stored in your browser if you choose “Use as reference in SpicyFrame”.
Why crop to 9:16 before making an AI video?
SpicyFrame renders vertical 9:16 videos. A photo already cropped to 9:16 keeps your framing, instead of letting the model zoom into the centre or extend the edges.
Can I crop to 4:5, 1:1 or 16:9 too?
Yes. Choose the ratio above the preview. 4:5 suits Instagram feed posts, 1:1 square posts and 16:9 horizontal video.
