Frequently asked questions
How the tools work, credits and billing, the API, and your data — everything in one place.
General
What is iotools.cloud?
iotools.cloud is a free collection of browser-based tools — converters, generators, calculators, formatters and more — for developers, designers and anyone who needs a quick utility without installing anything.
Do I need an account to use the tools?
No. Every tool works without signing in. A free account adds daily credits for the handful of tools that need server-side processing, plus favorites, presets and history that sync across your devices.
Are the tools really free?
Yes — every tool works without an account, and most of them run entirely in your browser, so your input never reaches our servers. Ads pay for the ones that don't.
How the tools work
Does my data ever leave my browser?
For most tools, no — they run entirely client-side, with zero network requests. A handful of heavier tools (certain file conversions, AI-assisted tools) need server-side processing; for those, your input is processed and discarded, never stored.
Which tools need the server, and why?
Only a small subset — mostly ones that need libraries or processing power a browser can't provide. Every tool page tells you upfront whether it runs in your browser or on our servers.
Is anything sent to the server stored or logged?
No. Whether a tool runs in your browser or briefly on our servers, we don't retain your input. Server-side tools also run behind guards that block requests to internal or private network addresses.
Credits & rate limits
What are daily credits?
A handful of tools need server-side processing. Those runs cost credits, and your allowance resets every day. Browser-side tools — the vast majority — cost nothing and are never metered.
What happens when I run out of credits?
You'll need to wait for the next daily reset, or upgrade to the Builder plan for a larger allowance.
Are browser-only tools ever rate-limited?
No — since they never touch our servers, there's nothing to limit. Server-side tools are capped at a set number of requests per minute, higher on the Builder plan.
Plans & billing
Is "Remove ads" a subscription?
No. It's a single payment and it never renews. Ads stay off your account for good, on every device you sign in on.
How do I manage or cancel my plan?
Everything lives in the Billing card on your account page, which opens the Stripe customer portal for invoices, cards and cancellation.
What's the refund policy?
Payments are handled by Stripe and we never see your card details. Credits are generally non-refundable once used, but if something went wrong with a purchase, contact us and we'll sort it out.
API, MCP & embeds
Is there a REST API?
A REST API for programmatic access to the tools is part of the Builder plan. Public API docs are coming soon — Builder customers can reach out via Contact in the meantime.
Is there an MCP server for AI agents?
Yes — the Builder plan includes an MCP server so AI agents can call the tools directly, alongside the REST API.
Can I embed a tool on my own site?
Yes, on the Builder plan — embeds let you drop a single tool into your own site.
Account, data & support
How do I delete my account or my data?
Email hello@iotools.cloud with the subject "Data Erasure Request", or use the Contact form — we'll delete or anonymise your account and contact-form data, except where we're required to keep records for legal or security reasons.
Do you sell or share my data?
No. We never sell or rent your personal information. We only share it with staff or contractors who need it to run the site, or when required by law.
How do I report a bug or request a new tool?
Use the Contact form — bug reports, feature requests and tool suggestions all go to the same place, and we read every one.
