Why essentials.sh

Nothing leaves your browser

Images, URLs, everything — processed locally. There is no server to upload to.

Instant, no signup

Open a tool, get your result. No accounts, no emails, no paywalls.

Shareable by design

Tool state lives in the URL, so a result you like is a link you can send.

Everything here is also available to software: a free REST API and MCP server expose the generators to scripts and AI agents, and every tool accepts prefilled links you can share with a teammate.
