FlowDiagram Canvas — free online poster and design editor
FlowDiagram Canvas is a free, browser-based design editor for posters, flyers, social
media graphics, invitations, certificates and business cards. You choose an artboard
size — an Instagram post, a YouTube thumbnail, A4, US Letter, a 24×36 inch poster or
any custom size in millimetres or inches — then arrange text, photographs, shapes and
drawings on it and export the result at exactly those dimensions.
It is a graphic design tool in the same family as other online design apps: templates
to start from, real typography with control over weight, letter-spacing and line
height, photo cropping, masks and colour filters, layers, alignment guides and
undo history.
Designs are created and stored entirely in your own browser. There is no account, no
sign-in, and no design content is uploaded to or stored on a server. The whole editor
is a single page that keeps working after the network goes away, and it can be
installed as a desktop application.
Export a finished design as a PNG or JPG at its exact pixel size, as an SVG vector,
or as a print-ready PDF at a real paper size.
Design and publishing software for posters, social media and print.
JavaScript is required to run the editor itself.
