What is a .SAI file?
Everything worth knowing about PaintTool SAI Image.
A SAI file is a layered painting document created by PaintTool SAI, a digital art program from SYSTEMAX Software Development. Only PaintTool SAI can open it; no other mainstream app reads the format. To use the artwork elsewhere, open it in SAI and export: PSD keeps the layers, PNG or JPG flattens to a single image.

Frequently asked questions
Do I need Photoshop to open a .SAI file?
No. This viewer reads your .SAI file directly: the finished image and every layer, without Adobe software or an account.
Is my design uploaded anywhere?
No. The file is decoded with a JavaScript reader.
Why does the image change slightly when I hide a layer?
At first you see Photoshop's own saved composite, which is exact. When you toggle layers we rebuild the image in the browser. Adjustment layers, layer effects and a few blend modes can't be reproduced exactly yet, and the panel tells you which.
Can I extract a single layer?
Yes. Click a layer's name, then Download this layer as PNG. You get the layer's pixels with transparency, at full resolution.
Why can't I open my PSD?
Very old PSDs, CMYK and Lab documents, or files saved without Maximize Compatibility and with unusual layer types may not open yet. You'll see what we detected and why.
