File Format Support

CreativeEditor SDK (CE.SDK) supports a wide range of modern file types for importing assets and exporting final content. Whether you’re working with images, videos, audio, documents, or fonts, CE.SDK provides a client-side editing environment with excellent media compatibility and performance—optimized for modern client-side hardware.

This guide outlines supported formats, codecs, and known limitations across media types.

Importing Media

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

Exporting Media

Category	Supported Formats
Images	`.png` (with transparency), `.jpeg`, `.webp`, `.tga`
Video	`.mp4` (H.264 or H.265 on supported platforms with limited transparency support)
Print	`.pdf` (supports underlayer printing and spot colors)
Scene	`.scene` (description of the scene without any assets)
Archive	`.zip` (fully self-contained archive that bundles the `.scene` file with all assets)

Importing Templates

Format	Description
`.idml`	InDesign
`.psd`	Photoshop
`.scene`	CE.SDK Native

Font Formats

Format	Description
`.ttf`	TrueType Font
`.otf`	OpenType Font
`.woff`	Web Open Font Format
`.woff2`	Compressed Web Open Font Format 2

Video & Audio Codecs

CE.SDK supports the most widely adopted video and audio codecs to ensure compatibility across platforms:

Video Codecs

H.264 / AVC (in .mp4)
H.265 / HEVC (in .mp4, may require platform-specific support)

Audio Codecs

MP3 (in .mp3 or within .mp4)
AAC (in .m4a or within .mp4 or .mov)

Size Limits

Image Resolution Limits

Constraint	Recommendation / Limit
Input Resolution	Maximum input resolution is 4096×4096 pixels. Images from external sources (e.g., Unsplash) are resized to this size before rendering on the canvas. You can modify this value using the `maxImageSize` setting.
Output Resolution	There is no enforced output resolution limit. Theoretically, the editor supports output sizes up to 16,384×16,384 pixels. However, practical limits depend on the device’s GPU capabilities and available memory.

All image processing in CE.SDK is handled client-side, so these values depend on the maximum texture size supported by the user’s hardware. The default limit of 4096×4096 is a safe baseline that works universally. Higher resolutions (e.g., 8192×8192) may work on certain devices but could fail on others during export if the GPU texture size is exceeded.

Video Resolution & Duration Limits

Constraint	Recommendation / Limit
Resolution	Up to 4K UHD is supported for playback and export, depending on the user’s hardware and available GPU resources. For import, CE.SDK does not impose artificial limits, but maximum video size is bounded by the 32-bit address space of WebAssembly (wasm32) and the browser tab’s memory cap (~2 GB).
Frame Rate	30 FPS at 1080p is broadly supported; 60 FPS and high-res exports benefit from hardware acceleration
Duration	Stories and reels of up to 2 minutes are fully supported. Longer videos are also supported, but we generally found a maximum duration of 10 minutes to be a good balance for a smooth editing experience and a pleasant export duration of around one minute on modern hardware.
