AVIF to BMP Details

When something needs BMP instead of AVIF, AVIF to BMP keeps every step on one screen: upload, queue, convert, download.

AVIF is the still-image half of the AV1 codec and holds detail well even at low bitrates. BMP stores pixels as they are, with no practical compression standing in the way.

Step by step

The order below follows the page itself, and no step asks you to sign up or confirm anything.

  1. Add the AVIF files you want converted by dragging them in or clicking to browse.
  2. Each queued file shows its name and size. Remove what you do not need; one round handles 20 files at most.
  3. Use the convert button on a single row, or the batch button to run the whole queue at once.
  4. Type a different name in the queue field if you want one, and the file lands with that name plus the BMP extension.
  5. Save the finished BMP file with the download link, then clear the queue and start the next batch.

Technical details

Here is the technical side of the conversion in short:

  • Accepted input: AVIF (avif), up to 24 MB per file.
  • The result is written as BMP and written with no compression applied.
  • The queue carries 20 files at a time, and each file travels in its own request.
  • AVIF can hold transparency and BMP cannot, so transparent pixels are flattened onto white.
  • BMP applies no compression, so the output file is clearly larger than the source.
  • AVIF was already compressed with loss, so writing BMP losslessly protects what is left instead of restoring detail.
  • Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.

When to choose this tool

If you hold AVIF files and the destination genuinely wants BMP, this is the right page. Legacy Windows tooling, a handful of printer drivers and software that wants raw pixels still ask for BMP. Files grow several times larger than the alternatives, and in exchange nothing is discarded. AVIF is the still-image half of the AV1 codec and holds detail well even at low bitrates.

If the transparent background has to survive, BMP is the wrong destination; pick the converter that outputs PNG or WebP instead.

Practical notes

  • Filling the queue with 20 files and hitting convert all is faster than working through them one by one.
  • Renaming outputs in the queue keeps your downloads folder readable once several BMP files land there.
  • BMP is written losslessly, so saving again does no damage and the file works as an archive copy.
  • Before publishing, confirm the destination accepts BMP; some upload panels keep a short format list.

Data and privacy

Your file travels over HTTPS, is processed during that single request and comes back as the download itself. It is never written to a public directory, nothing is kept once the response is sent, and the download is marked as non-cacheable.

Frequently asked questions

Drop your AVIF file into the upload area, start the conversion, and download the finished BMP file. No installation or plugin is needed.

You can add up to 20 files to the same queue. The per-file size limit is shown under the upload area.

Check that the file really is in AVIF format and stays under the size limit. Partially downloaded or corrupted files cannot be read.

Lossless formats keep sharp edges and text clean, while smaller formats are better when page speed matters. Try both and compare the file sizes.
