Understanding sai2 and sai file formats
SAI2 and SAI are proprietary file formats used by PaintTool SAI, a popular lightweight digital painting software developed by Systemax. The .sai2 format is used in PaintTool SAI version 2, while the .sai format is from the original PaintTool SAI version 1. Both formats support layers, transparency, and other advanced painting features, but they are not directly interchangeable due to differences in software versions and features.
Why convert sai2 to sai?
Converting a SAI2 file to SAI format may be necessary if you need to open your artwork in the older version of PaintTool SAI or share it with someone who only has access to SAI version 1. However, be aware that some features or layer types available in SAI2 may not be supported in the older SAI format.
How to convert sai2 to sai
There is no direct, official converter for SAI2 to SAI due to the proprietary nature of these formats. However, you can use the following workaround:
- Open your .sai2 file in PaintTool SAI 2.
- Flatten or simplify any advanced layers or features not supported in SAI 1 (such as vector layers or new blending modes).
- Go to File → Export As → SAI File (v1) if your version of SAI2 supports this. Some beta versions of SAI2 include this export option.
- If the export option is not available, export your artwork as a layered PSD file (File → Export As → PSD), then open the PSD in SAI 1 and save it as a .sai file.
Best software for sai2 to sai conversion
The best software for this conversion is PaintTool SAI 2 itself, as it is the only application that can natively open .sai2 files and, in some versions, export to .sai. If you do not have access to SAI2, you can try exporting to PSD and then using SAI 1 to save as SAI, but this may result in some loss of features or layer information.
Important tips
- Always keep a backup of your original .sai2 file before converting.
- Check your artwork after conversion for any missing layers or effects.
- Consider flattening or merging complex layers to ensure compatibility.
