This fix should allow you to use MS Paint to Open and Save JPG files, and Open and Save GIF files. The quality of the saved GIF with MS Paint may be reduced because of the limited 256-color palette (See here for an explanation and workaround). A better alternative for opening and saving JPG and GIF files would be to download and install a great FREE image viewer called IrfanView (MS Paint is still better for individual pixel editing, so it's good to have both).
If you want to proceed with the MS Paint Fix, you should first do a search on your hard drive to see if you
have the jpegim32.flt and gifimp32.flt filters.
You can find those files here:
You need to make sure you have both filters in the following folders:
C:\Program Files\Common Files\Microsoft Shared\grphflt
You may already have the JPEG Filter on your system, but only in one location. If that is the case, Copy and Paste it to the other location. Once you have the JPEG Filter in both locations, you may only need to do a simple Registry edit to be able to "Save As" a JPG.
If you already have the JPEG Graphics Filter on your system (and in both locations as stated above), but MS Paint still won't let you "Save As" JPG, you can manually edit the Registry to correct this. It's a simple fix. Go to Start, Run, type REGEDIT, and click OK. Go to this key by clicking the + signs beside the keys (folders):
HKEY_LOCAL_MACHINE\Software\Microsoft\Shared Tools\Graphics Filters\Export\JPEG.
Click on the "JPEG" key (folder) in the left pane, and you'll see a String Value in the right pane with the name "Extensions". Make sure under the "Data" column it shows only "jpg". If it shows "jpg, jpeg", double-click on the "Extensions" string and from the "Value data" field remove "jpeg" so that it only reads "jpg" (without the quotes).
If it worked, this edit allows you to "Save As" JPG. If it didn't work, or if you want to be able to also open and save GIF files, read on.
Or use this reg file to export your files as jpeg
