About XBM
XBM comes from MIT's X Window System of the 1980s, where it drew icons, cursors and patterns, and the first web browsers showed it as images. X11 apps still carry icons in it.
An XBM is C source: its width and height as #defines, then an array of bytes with a bit for each pixel, 1 for black, which a program compiles into itself.
No browser shows XBM any more. Filepeek reads its numbers from the text and draws the bitmap without compiling or running anything, and Export saves it as PNG.

Questions
How do I open an XBM file?
Drop it on this page or press Peek an XBM. It opens at full size, with nothing to install.
How do I convert XBM to PNG?
Open it, then choose Export and Save as PNG.
Does opening an XBM run its code?
No. Filepeek only reads its width, its height and its numbers as text, and nothing in it is compiled or run.
Is my bitmap uploaded?
No. It opens inside your browser and never leaves your device.
