RLA to SK1 conversion is the process of transforming image data stored in the RLA raster image/archive format (commonly used for film, VFX, and scanline-rendered images with multiple channels like depth and matte) into the SK1 vector/bitmap hybrid format used by Serif’s DrawPlus/Draw applications. This conversion typically involves mapping RLA image channels and raster layers into a single SK1 document, preserving raster pixels and embedding layers or metadata where possible for editing in SK1-compatible software.

RLA files use the MIME type image/x-rla and are typically used in professional 3D rendering pipelines to store multilayer images with alpha channels. SK1 files use the MIME type application/x-sk1 and are commonly used for vector illustrations with support for multiple layers and objects. Conversion involves translating raster-based RLA data into editable vector SK1 components.
The SK1 (.SK1) format is commonly used for drawing. Understanding its characteristics can be helpful when converting to or from other formats like RLA.
While specific technical details aren't available here, SK1 files generally serve the purpose of storing drawing effectively within their domain.
Easily convert your RLA files to SK1 format using our online RLA to SK1 converter. Designed for seamless, hassle-free conversions, our tool supports high-quality output tailored to your needs without requiring software installation.
RLA is primarily a high-resolution image file format used in 3D rendering and compositing, while SK1 is a vector graphics format optimized for scalable illustrations. RLA files are often larger and more complex, whereas SK1 files focus on editability and smaller file sizes. Choosing SK1 over RLA improves workflow efficiency in graphic design applications.
Keep original RLA masters under 50–200MB for quick single-file conversions; larger files increase processing time and memory use.
To preserve maximum quality, export the RLA with all channels (RGBA + depth/matte) intact and choose a high-quality SK1 export with no downsampling.
For batch conversions, group files by resolution and channel configuration to avoid repeated manual settings and use automated CLI or batch tools when available.
Note format limitation: SK1 is primarily a vector/illustration document that supports embedded rasters but does not natively preserve all RLA multi-channel metadata (e.g., per-pixel depth or elaborate render passes) as separate editable channels.
