For an extensive list of emulators, see The Stairway to Hell here.
The last time I checked (28/07/2026) the list wasn't quite up to date but it's a good starting point to find what you are looking for.
I highly recommend the emulators I use most: Beebem, and B-Em. Tom Seddon's
B2. Each have their own unique very useful uses, most will do what the average user will want.
Jsbeeb by Matt Godbolt (thank you) is an online emulator that you will find here on the 8BS website containing the vast majority of the 8BS pool. It does run well on android but you do need a physical keyboard. I have not yet found a way to make the virtual keyboard work with it. That's not to say there isn't a way. Please let me know if you manage it.
I used to laboriously read BBC discs in to the PC using various now outdated bits of software that I have now removed from this page. One thing worth leaving though is this for DOS image creation:
Virtual Floppy Drive at http://vfd.sourceforge.net/
Two must have pieces of software from Jon Welch (thank you) are the explorers. I use these extensively for file handling between disc images. Invaluable. Drag and drop, create images of any sort, various disc utilities. They each require registering but are worth every penny:
DFS.net Explorer
Now, the best way of creating disc images from real floppies as I type this (9 4 2021) is to use John Kortink's GoSDC. More or less plug and play hardware that uses an SD card to transfer both ways between PC and BBC.

I wrote this when double density discs were rare and high density discs were ten a penny. I think they are all rare now. Using an HD floppy as DD, note that after about 100 uses the HD floppy is going to be wrecked. Use an opaque material to cover the hole by the way.
