How many tools does AlteredIdea have?

226 and counting: spread across PDF, developer tools, image editing, SEO, converters, security, marketing, and more. New ones get added regularly.

Do all of them run in the browser?

Yes, every single one. No server-side processing anywhere on this list. That's a deliberate architectural choice, not just a marketing claim.

Are some tools better on desktop than mobile?

Most work well on both. A few: like the PDF editor, code formatters, or the diff checker: are a lot more comfortable with a keyboard and bigger screen. Things like the QR code generator or unit converter are fine on phone.

Can I bookmark a specific tool?

Yes. Each tool has its own URL and works as a standalone page. Bookmark whichever ones you reach for regularly.

Is there a way to search all 226 tools?

Yes: the search bar in the top navigation filters across all tools. Start typing a tool name or format like 'JSON' or 'PDF' and results come up instantly.

Will the tools stay free?

Yes. They've been free since day one and that's not changing. The paid tier covers team Workspace features, not the individual tools.
