Format Details

.xbm

XBM

XBM (X BitMap) is a monochrome raster image format native to the X Window System, used on Unix-like operating systems. Uniquely, it stores bitmap data as a C language source code array, making it directly includable in C programs without any parsing library. XBM is primarily used for small monochrome icons and cursor bitmaps in X11 applications, though it is rarely encountered outside of this ecosystem.

.avif

AVIF

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec developed by the Alliance for Open Media. It delivers superior compression efficiency compared to JPEG and PNG, often reducing file sizes by 50% or more while maintaining excellent visual quality. AVIF supports HDR, wide color gamut, and transparency, making it an ideal choice for the modern web.

Converting XBM to AVIF: what actually changes

XBM to AVIF is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.

What .XBM and .AVIF each hold

.XBM is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .AVIF is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.

What changes in the conversion

Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .AVIF encodes pixels, dimensions and colour depth — not what the file is about.

When this conversion is the right one

Reach for .AVIF when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .AVIF to .XBM using the same tool.

Tips for a clean XBM to AVIF conversion

1

Start from the original file

Convert the .XBM you started with, not an earlier .AVIF output. Every extra round trip costs quality and can accumulate formatting drift.

2

Check the real type, not the extension

Image/x-xbitmap becomes image/avif. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.

3

Watch transparency and animation

If the .XBM has a transparent background or animation, confirm .AVIF supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.

Limits worth knowing

Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
