Transparent areas

  • GIF can only use 256 colours, so photos may look grainy. Its transparency is on or off, so soft edges are blended onto the background colour you pick.

How to convert BMP to GIF

  1. Drop your BMP files in the box above. You can also click the box to pick files, or paste them.
  2. Each file is converted to GIF on your own device. It usually takes a second or two.
  3. Download each file, or get them all in one zip. Every file keeps its name.

Why convert BMP to GIF?

Most people do this because something they are using will not accept BMP files.

GIF files are usually a little smaller than BMP.

GIF transparency is on or off with nothing in between, so soft edges are blended onto the background colour.

About the two formats

BMP: A plain Windows format with no compression. Files are big, but even very old programs can open them.

GIF: Very old but still everywhere. It can only use 256 colours, so photos look rough, but every app can open it.

The whole conversion happens in your browser. Your file is unpacked into raw pixels and saved again as GIF. Nothing is sent to any server.

Common questions

Is the BMP to GIF converter free?

Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.

Are my files uploaded to a server?

No. The BMP to GIF converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.

Does converting BMP to GIF lose quality?

No. Both BMP and GIF store every pixel exactly as it was, so the picture that comes out is identical to the one that went in. Only the file size and what can open the file change.

Does GIF keep the transparency from my BMP?

Partly. GIF transparency is on or off for each pixel with nothing in between, so a fully see-through area survives but a soft or faded edge can't. Those half transparent pixels are blended onto the background colour you choose, which stops the ragged halo you would otherwise get around the edges.

Will the GIF file be smaller than the BMP?

Usually a bit smaller, though the gap isn't dramatic. The exact saving depends on the picture. If size is the whole reason you're here, the compress tool will hit a number you name instead of leaving it to chance.
