What You'll Learn

Save as a .PNG file
To save your Paint Tool SAI file as a transparent PNG, you need to ensure that your file has layers rather than being a flat image. This is because it is easier to export your art as a .PSD file and then add transparency using a compatible image-editing software such as GIMP.
Once you have downloaded and installed GIMP, open your .PSD file in the program. You can do this by clicking "File" and then "Open" in the menu bar, and then selecting your desired file. If you are using clipping group layers, you may need to merge these with the layer underneath.
Next, right-click on the layer in the layers toolbox and select "Add alpha channel". You can then use the eraser or wand tool to erase the parts of the image that you want to be transparent.
Finally, you can save your file as a PNG by selecting "File" and then "Export" in the menu bar. Make sure to select ".png" as the file type and tick the boxes for "Save gamma" and "Save color values from transparent pixels". Your image should now have a transparent background!
It is important to note that not all versions of Paint Tool SAI support transparent PNG files. If you are unable to save your file as a transparent PNG directly in SAI, you can follow the steps above to add transparency using GIMP or a similar image-editing program.

Update Paint Tool SAI to access new features
Paint Tool SAI is a software developed by a one-man team led by Koji Komatsu. The latest version, Paint Tool SAI 2, offers several new features, bug fixes, and changes.
To access these new features, you will need to update your software. If you have a license for SAI Version 1, you can remove the lock on save and load all the features with your license certificate. Here's a step-by-step guide to updating to SAI Version 2:
Firstly, download a new license certificate with the System ID of SAI Version 2. You can find this by opening your trial version of SAI Version 2, clicking on Help, and then System ID. Once you have the System ID, download the new license certificate.
Next, you can purchase the software license for SAI Version 1 from the official website. After purchasing the license, you can download and install SAI Version 2 from the same website.
With SAI Version 2, you will notice improvements in handling transparency. When saving your file as a PNG, SAI 2 should automatically handle any transparency. Simply hide any background layers, click on Canvas, hover over Background, and select Transparent (Bright checker). Your drawing should display some grey checkerboxes if it is transparent.
Additionally, when saving as a PNG, ensure that you tick the box for preserving every pixel to maintain transparency. You can also use the GIMP image-editing software in conjunction with SAI to add transparency to your images.
By following these steps, you will be able to update Paint Tool SAI and access the new features offered in the latest version.

Use the magic wand tool
To save a Paint Tool SAI file as a transparent PNG, you must first export your art as a .PSD file. Then, open the file in a compatible image-editing software like GIMP, which is free and compatible with Windows and Mac. In GIMP, you can then save your file as a .PNG, ensuring that "Save gamma" and "Save color values from transparent pixels" are selected.
Now, for using the Magic Wand Tool in Paint Tool SAI:
The Magic Wand Tool is a versatile selection tool that allows you to capture a closed selection and colour within it without going beyond the selection's edges. You can adjust the tool's size, opacity, pen pressure, and even add texture. It offers three detection modes: Transparency (Strict), Transparency (Fuzzy), and Colour Difference. The latter is the most useful, as it selects things based on their colour, and you can adjust the "Colour Diff." bar to determine how strict the selection will be. This is particularly handy when you want to select a specific coloured area or all areas of a particular colour.
Additionally, the Magic Wand Tool features two handy settings: "Invert" and "Increment". "Invert" does exactly what it says—it inverts your selection. However, when coupled with the "Increment" tool, it becomes even more useful. By selecting the outside of your lineart and clicking "Increment" a few times, you can prevent the colour from bleeding through when you invert your selection.

Save as PSD and open in Photoshop
To save your Paint Tool SAI file as a transparent PNG, you must first ensure any background layers are hidden. Then, click on "File", select "Export as", and choose "\.png" as the file format.
If you want to save your Paint Tool SAI file as a PSD and open it in Photoshop, you can do so by following these steps:
- In Paint Tool SAI, go to "File" and select "Export as" or "Save As".
- Choose ".psd" as the file format.
- Open Photoshop and create a new document or open an existing one.
- Go to "File" and select "Open".
- Navigate to the location where you saved your PSD file and open it.
It is important to note that saving as a PSD file may cause some changes to the transparent data in SAI. If you plan to edit the file further in SAI, it is recommended to keep the original SAI file and make edits to the PSD file in Photoshop.
Additionally, if you are using clipping group layers in SAI, you may need to merge those specific layers with the layer underneath before saving as a PSD file. This is because the clipping group layers may not transfer properly to Photoshop.
By following these steps, you should be able to successfully save your Paint Tool SAI file as a PSD and open it in Photoshop for further editing or collaboration.

Frequently asked questions
First, ensure that you have a file with layers rather than a flat image. Then, hide any background layers and click on "Canvas", hover over "Background", and select "Transparent (Bright checker)". If your drawing is transparent, grey checkerboxes will appear. Finally, export and save your file as a .PNG.
You can use a workaround by drawing in SAI and leaving the bottom layer empty, which will function as the background layer later on. Then, save the file as a .PSD file, open it in Photoshop or GIMP, and save it as a .PNG.
When saving as a PNG, there is usually an option to preserve "every pixel". Make sure to check the box for this option, which is not checked by default.
You can use the Magic Wand tool or the Bucket Tool to select and delete the background. Alternatively, you can use external software such as GIMP or Pixlr.com to add transparency to your image.
File formats such as ".PNG" and ".JPEG" support transparency. It is recommended to use .PNG as it occupies less space and is better suited for transparent images.
