Should you convert WEBP to BMP?

A safe conversion when BMP is what you need: both WEBP and BMP keep every pixel, so the picture itself doesn’t change.

BMP is also the more widely supported of the two: it opens almost everywhere, while WEBP is opens in current browsers and apps.

WEBP is a web image format that can be lossy or lossless, with transparency and animation; BMP is an uncompressed grid of pixels. Use BMP only when a specific piece of software, a printer or an embedded device asks for it.

How to convert WEBP to BMP

  1. 01

    Add your WEBP

    Drop your WEBP image onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to BMP. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the BMP

    Press convert and save the BMP. Several files come back together as a ZIP.

What changes when WEBP becomes BMP

BMP can’t hold transparency

Any transparent area in the WEBP has to become a solid color, because BMP has no alpha channel. The background setting decides which color; white suits documents and most uploads, but pick the color of the page it will sit on if you know it, because it can’t be undone later.

Animations become a still

BMP can’t move, so an animated WEBP is saved as its first frame. Choose GIF or APNG instead to keep the animation.

Expect a much larger file

BMP is far bigger for the same content. Choose it because something needs BMP, not to send or store the file. WEBP: Typically 25–35% smaller than the same JPG. BMP: A 12-megapixel image is about 36 MB.

This page is put together from our notes on each format, choosing only what is true of WEBP and BMP, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Changing a picture’s format is work your browser already knows how to do. Sending your photos to a server first only adds waiting and risk, so nothing is sent.

How to check for yourself

Worth knowing

  • About the WEBP. Images saved from websites arrive as WEBP even when the page looked like it showed a JPG, and then a document editor or upload form refuses them.
  • About the BMP. BMP looks like a safe “raw” choice, but a single photo can run to tens of megabytes and most sites refuse it.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting WEBP to BMP lose quality?

No. WEBP and BMP are both lossless, so every pixel is kept.

What happens to a transparent background when converting WEBP to BMP?

BMP has no transparency, so transparent areas are filled with the background color you choose, white by default.
