WHY THESE TOOLS EXIST

Simple tools, clear boundaries

Local content processing

The linked tools perform their core text, image, and document processing locally in the browser rather than sending your content to an Amosfot processing backend.

No account gate

The current utility workflows do not require an account. Open the tool, do the task, and keep the result you create.

Honest results

The file utilities validate concrete requirements and do not silently claim success when a generated result fails the rules you entered.
