1. Choose a template and first screenshot
In Lilacpane, choose a filled device-frame template or add a frame to the first canvas. Import a screen-only screenshot; check the phone opening, background, headline and canvas ratio before adding more images.
2. Add media to separate canvases
Use + in the batch strip to select more images. The app groups imported media into canvases using the selected template. A multi-frame template may place several images on one canvas, so inspect the strip before exporting.
Review the frame position, background and title on every canvas. The app syncs shared style before export, but each screenshot can have different cropping and a different effective output size.
3. Choose Batch in the export panel
Open Export. When there is more than one canvas, the Batch action appears beside the current-canvas Share and Save actions. Batch saves all canvases and requires Pro. The app renders each canvas in order; a split canvas can produce multiple image pages.
Choose the available long-edge size and PNG or JPEG for images. A canvas containing video exports as video; check its options separately. Different canvas ratios do not become one guaranteed App Store size just because Batch was selected.

4. Review the saved set and upload order
Batch export does not assign your marketing filenames, folders or App Store upload order. Organize the files after saving, and adjust one canvas in the app before re-exporting if a result needs correction.
FAQ
When does the Batch button appear?
When the project has more than one canvas. It saves all canvases and requires Pro.
Are all exported images the same dimensions?
Not necessarily. Each canvas uses its own aspect ratio and export scaling. Inspect the saved width and height before uploading.
Does the app name and upload the whole set?
The app exports the canvases. File naming, folders and the order you set in App Store Connect still need your review.
