Embed any tool on your site
Every one of the 138 tools here works as a drop-in widget. One line of HTML, no API key, no account, no request limit — and because the tools run entirely in the visitor's browser, embedding one never makes your site responsible for handling somebody else's files.
Embed QR Code Generator on your site
Free for any site, commercial included. No API key, no account, no limits.

What you get
Nothing to sign up for
No key, no dashboard, no rate limit to monitor. The iframe is the whole integration, and it does not stop working when a free tier runs out.
No data liability
Files and text are processed in your visitor's browser and never reach a server — ours or anyone's. Embedding a tool adds no processing you have to account for.
Lazy by default
The snippet ships with loading="lazy", and the embed page drops the site header, footer and analytics. A widget below the fold costs almost nothing on load.
All 138 embeddable tools
Every tool below embeds at /embed/{slug}. Open a tool to build its snippet, or pick it from the selector above.

12 toolsQuestions
Can I embed these tools on my website for free?
Yes. All 138 tools can be embedded on any site, including commercial and client work, at no cost. There is no API key, no account, no request limit and no separate licence to agree to. Paste the iframe and it works.
Do I have to credit Quill Tools?
The embedded tool carries a small 'Powered by Quill Tools' line in its own footer, so credit is already present and you do not need to add anything. The copy-paste snippet includes a matching caption underneath, which you are free to delete.
Does the embedded tool upload my visitors' files?
No. An embedded tool behaves exactly like the full version: all processing happens in your visitor's browser, and no file or text is sent to a server. Nothing you embed makes your site responsible for handling someone else's data.
Will embedding a tool slow my page down?
The iframe is marked loading="lazy", so the browser does not fetch it until the visitor scrolls near it. A tool below the fold costs essentially nothing on initial page load, and the embed page ships without the site header, footer or analytics.
Can I change the size of the embed?
Yes. Width is set to 100% so it fills whatever container you put it in. Height is a fixed pixel value you control — the builder above offers 420, 620 and 860 pixel presets, and you can type any value directly into the snippet.
Do the embeds keep working if you change the site?
Embed URLs follow the pattern /embed/{tool-slug} and the slug is the same identifier used by the tool's own page, so it stays stable. If a tool were ever retired, its embed would stop rather than silently show something else.
