How-tos
First-hand guides for the live tools. Written by Simon Wong.
sw-commercial.com/blog
How these tools are written
Simon Wong tests each live tool on this hub, then writes the how-to on sw-commercial.com. The guides name failure cases — a HEIC that is a Live Photo, a merge with the pages in the wrong order, a JPEG already too small to shrink. They are not swapped templates from products that 404.
Every file job on this page runs in your tab. We do not take the file. Invoice Studio and Rezimo are separate hosts because they are documents you draft, not one-shot converters. Open a tool below, or read the catalog how-tos first.
