How to convert BMP to GIF with FileFlip

  1. Select the BMP files

    In Finder or on the Desktop. One file, or a whole folder with ⌘ A.

  2. Press ⌥ F

    FileFlip opens next to the selection and lists the formats it can make from BMP. Type “GIF” to jump to it.

  3. Choose GIF and press Return

    The GIF files appear next to the originals with the same names. The BMP files stay as they are.

BMP and GIF

BMP files are uncompressed and take far more space than they need to. GIF animations play everywhere, from chat apps to old email clients.

What changes when you convert

  • Both formats are lossless, so the image itself doesn’t change. Only file size and compatibility do.
  • GIF is limited to 256 colors, so photos can look grainy or banded.

Other ways on a Mac

For one file now and then you may not need FileFlip. These work with what’s already on your Mac.

Preview

Open the BMP in Preview, choose File → Export, pick GIF from the Format menu and click Save. If GIF isn’t listed, hold Option while you click the Format menu. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.

Good for a few files now and then.

Terminal

The sips command converts images in place or into a new file.

sips -s format gif image.bmp \
  --out image.gif

Built into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.

Questions about BMP and GIF

Does converting BMP to GIF lose quality?

Both formats are lossless, so the image itself doesn’t change. Only file size and compatibility do.

Can I convert many BMP files at once?

Yes. Select them all in Finder, press ⌥ F and choose GIF. Progress moves to the menu bar, so you can close the panel and keep working.
