WEBP to BMP Converter

Convert WEBP files to BMP free in your browser — no signup, no install, and the file is never uploaded to a server. BMP opens almost anywhere, so the result works where WEBP did not.

What changes in this conversion

  • BMP does not support transparency, so transparent areas are filled with a solid background (white by default).
  • Converting to BMP stops any further quality loss, but it cannot restore image detail already discarded by WEBP. The file will usually get larger.
  • BMP holds a single frame, so only the first frame of the animation is kept.
  • BMP opens almost everywhere, so the converted file will work on devices and programs that refused the original WEBP.

How to use

  1. Add your WEBP file

    Drag the WEBP file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm BMP as the output

    BMP is already selected as the output format on this page. You can set the output width and height. Quality stays untouched because this format is lossless.

  3. Run the conversion

    Press the convert button. A single image is usually done before you finish reading this sentence.

  4. Download the BMP file

    When it finishes, download the BMP file. Converting multiple files gives you the option to download them together as a ZIP.

About these formats

WEBP WebP Image

Frequently asked questions

Is converting WEBP to BMP really free?

Yes. WEBP to BMP conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my WEBP files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the WEBP file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Will my transparent background survive the WEBP to BMP conversion?

No — BMP has no alpha channel, so transparent pixels are replaced with a solid background. If transparency matters, convert to PNG or WebP instead.

What happens to the animation when I convert WEBP to BMP?

BMP stores a single frame, so only the first frame is kept. To preserve motion, convert to an animated format such as WebP or MP4.

Does the BMP file get bigger than the WEBP?

It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.

Is there a file size limit for WEBP to BMP conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
