About Shadow Snap

Created by Ward Lu and Shadow Lab, Shadow Snap helps film fans and content creators turn a single movie still and multiple dialogue lines into a long subtitle image. It keeps the first frame intact, then joins slices of the lower subtitle region beneath it.

Key features

  • Keep the first frame intact and stitch the following subtitle slices automatically.
  • Process and export images locally with HTML5 Canvas without uploading photos.
  • Choose Chinese, Latin, Thai, Vietnamese and Arabic fonts. Adjust type size, colors, outlines, safe margins and watermarks.
  • Free to use without an account or installation. Import one image at a time.

Make a subtitle image in three steps

  1. Import a movie still or video screenshot in JPG, PNG or WebP format.
  2. Enter dialogue, using a new line for each subtitle slice.
  3. Adjust the font, slice height and watermark, then select Export Image. On mobile, save through the share sheet or long-press the image.

Frequently asked questions

What is Shadow Snap?

Shadow Snap is a free cinematic subtitle image maker that combines one still image with multiple dialogue lines. No account or installation is required.

How do I create a movie dialogue image?

Import one image, enter dialogue on separate lines, adjust the font and slice height, then export. The first frame stays intact and subsequent lines use slices from the lower region.

Are my photos uploaded to a server?

No. Image processing and export run in your local browser memory. The site loads fonts and uses website analytics; neither requires uploading your images.

How do I save an image on mobile?

After exporting, save the image through the system share sheet. Browsers without sharing support offer a long-press save panel. If saving inside WeChat fails, open the page in your system browser.

Which languages and fonts are supported?

The interface is available in Chinese and English. Font options include Chinese, Latin, Thai, Vietnamese and Arabic scripts. Rendering depends on your browser and font availability.
