SquishPic will open and save SID images without using your data plan.
NOTE: The following instructions suggest using File > Save As to save a new copy of your file. If instead you use File > Save, your existing file will be overwritten with the new file.
TIP: You can also use the Compress Image function on an existing SID file to compress it even further; this operation does require a data plan.
Updating old format SID files
If you have MG2 or MG3 format SIDs that you want to convert to MG4:
Open the old-format SID in SquishPic.
Choose File > Save As, then select a destination folder and name for the new file.
TIP: If you don’t change the file location or name, the MG4 file will overwrite the existing file. If this is not your intention, then we suggest at least adding -mg4 just before the file extension, so for example a file named
michelangelo-david.sid will be resaved as
Changing a SID image
If you need to have a modified version of a SID, you can make multiple changes to the image, then save it.
Open the image in SquishPic.
Click Image Editor if the tools are not already displayed.
Use the various editing tools to modify your image:
Rotate and Flip
Levels and Filters
See Image operations for details on using these tools.
Click to zoom in to your image or to zoom out; when zoomed, click and drag in the image to pan to another area.
When you have made the changes you need, choose File > Save As, then select a destination folder and name for the new file.
TIP: If you don’t change the file location or name, the new file will overwrite the existing file. If you don’t mean to do this, we suggest changing the filename to reflect the changes you have made. For example, if you crop
warhol-soupcan.sid, name the new file as
