Should you convert APNG to BMP?

A safe conversion when BMP is what you need: both APNG 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 APNG is opens in current browsers and apps.

APNG is a PNG that animates, with full color and soft transparency; 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 APNG to BMP

  1. 01

    Add your APNG

    Drop your APNG 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 APNG becomes BMP

Nothing is discarded

APNG and BMP both keep every pixel, so the picture survives the move intact. You can convert back and forth as often as you like without it degrading.

BMP can’t hold transparency

Any transparent area in the APNG 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 APNG is saved as its first frame. Choose GIF or APNG instead to keep the animation.

Expect a larger file

BMP generally takes more room than APNG. If the file has to fit an upload limit, check the size once it’s converted. APNG: Larger than a GIF of the same animation, but in full color. BMP: A 12-megapixel image is about 36 MB.

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 APNG. An APNG usually still ends in .png, so an upload form or editor treats it as a still picture and the animation silently disappears.
  • 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 APNG to BMP lose quality?

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

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

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