What is ClickZM?
ClickZM is a free collection of 387 online tools for PDFs, images, text, SEO, code, calculations, finance, social media, security, networking and design. No account is needed.
Are my files uploaded?
No for PDF, image, audio, video and text tools: they run in your browser, so files stay on your device. Website, DNS and SSL checkers use our server or public DNS because browsers cannot make those lookups themselves, and AI tools send your prompt to the AI model.
Is ClickZM free?
Yes. Every tool is free, with no watermark, no signup and no daily limit.
Every tool page starts with a direct answer, explains the formula or method it uses, and lists the questions people ask most. Read more: Guides · FAQ
