Overview

You can trigger conversions programmatically with the Android Engine API or let users start exports through the editor UI.

Supported Input and Output Formats#

CE.SDK accepts a range of input formats when working with designs, including:

Category	Supported Formats
Images	.png, .apng, .jpeg, .jpg, .gif, .webp, .svg, .bmp
Video	.mp4 (H.264/AVC, H.265/HEVC), .mov (H.264/AVC, H.265/HEVC)
Audio	.wav, .mp3, .m4a, .mp4 (AAC or MP3), .mov (AAC or MP3)
Animation	.json (Lottie)

Animated images (.gif and .apng) import as a static first frame in design scenes and as a looping video fill in video scenes.

When it comes to exporting or converting designs, the SDK supports the following output formats:

Category	Supported Formats
Images	.png, .jpeg, .tga
Vector	.svg with text exported as paths
Print	.pdf with compatibility and underlayer options
Video	.mp4
Scene	serialized scene strings for .scene workflows
Blocks	proprietary block strings or block archive entries such as blocks.blocks
Archive	.zip archives with scenes or blocks and their assets
Raw Data	binary RGBA8888 image data through MimeType.BINARY

Each format serves different use cases, giving you the flexibility to adapt designs for your application’s needs.

Conversion Methods#

Use the conversion path that matches how much control your Android app needs over the export workflow.

Method	Android API	Use it for
Programmatic image, vector, PDF, or raw binary export	engine.block.export(...)	Exporting a scene, page, group, or block from Kotlin with a selected MimeType and optional ExportOptions.
Programmatic video export	engine.block.exportVideo(...)	Exporting a page timeline to MP4 while receiving progress updates.
Scene and block serialization	engine.scene.saveToString(scene=_), engine.scene.saveToArchive(scene=_), engine.block.saveToString(blocks=_), engine.block.saveToArchive(blocks=_)	Persisting editable CE.SDK content either as a serialized scene string or archive, or as proprietary block data or a block archive.
Color-mask export	engine.block.exportWithColorMask(...)	Creating image data plus a mask for workflows that need a separate color mask.
Editor UI export	onExport / built-in export action	Letting users export from the Android editor UI while your app controls the final export handling.

Programmatic exports return binary data that your app can write to storage, upload, share, or pass to another workflow. UI-driven exports are useful when the editor should remain user-facing and the app only needs to customize what happens after the user taps export.

Customization Options#

Android exports combine scene-level settings with ExportOptions for static formats and ExportVideoOptions for MP4 output.

Option	Applies to	Purpose
targetWidth / targetHeight	Static and video exports	Render output at a specific size while preserving the block aspect ratio.
scene/dpi	Scene exports and design units	Set print metadata and the pixel-to-inch or millimeter conversion, either while creating an image scene with engine.scene.createFromImage(imageUri = imageUri, dpi = 300F) or later with engine.block.setFloat(block = scene, property = "scene/dpi", value = 300F).
pngCompressionLevel	PNG	Balance file size and encode time without changing visual quality.
jpegQuality	JPEG	Control compression quality for JPEG exports.
exportPdfWithHighCompatibility	PDF	Rasterize effects and images for broader PDF viewer compatibility.
exportPdfWithUnderlayer and underlayer settings	PDF	Generate print underlayers for production workflows that require them.
frameRate, bitrate, and H.264 settings	MP4	Tune video export quality, size, and encoding behavior.

Check engine.editor.getMaxExportSize() before large raster exports so the requested dimensions stay within the device-supported export limit. Use targetWidth and targetHeight for explicit pixel dimensions; changing scene/dpi does not replace those pixel-size controls.
