Whilst looking for a simple way to merge two images for a recent blog post, I came across FilesMerge, a really useful website. You can merge image files easily in a variety of ways, along with many other formats (although I haven’t tried these yet).

There’s also an online Voice Recorder, where you can use the microphone to record your voice, cut and edit it, and save it as an MP3 file. The recorder runs directly in the browser without installing additional software.
