Media Formats and Limits

Soku supports a range of video and image formats for uploading to the Media Library. This page covers accepted file types, size limits, and automatic conversions that Soku applies to ensure compatibility across social media platforms.

Accepted Video Formats

MP4 is the most widely supported format across all social platforms. If you are unsure which format to use, MP4 is the safest choice.

Accepted Image Formats


Automatic Conversions

PNG to JPEG

When you upload a PNG image, Soku automatically converts it to JPEG format. This conversion happens in the background and ensures that your images are compatible with all supported social media platforms, since not every platform accepts PNG files in all contexts. The converted JPEG version is what gets stored in your Media Library and used when publishing.
If your image relies on transparency (which JPEG does not support), be aware that transparent areas will be filled with a white background during conversion.

Accepted Upload Content Types

When uploading via the API or the Media Library, the following MIME types are accepted:

Platform-Specific Considerations

Different social media platforms have their own media requirements (resolution, aspect ratio, duration). Soku handles the publishing-side formatting, but for best results keep the following in mind:
