Free Marketing Tools for Small Businesses

Mintli's free marketing tools run entirely in your browser. There is no account to create, no watermark on the output and no cap on how often you use them. They are small, single-job tools built for UK small business owners who need something finished in the next five minutes.

The Instagram Mockup Generator turns a photo, a handle and a caption into a realistic Instagram feed post preview and downloads it as a PNG. Use it to show a client what a post will look like, to test whether a photograph survives Instagram's square crop, or to check where a caption gets cut off before you publish it.

Every tool here is free because it costs nothing to run. The work happens on your own device, so no image or caption is ever sent to a Mintli server. If you need the finished post rather than a preview, the main Mintli product writes the copy and creates the image from your website, with plans from nine pounds a month.
