Frequently Asked Questions

Everything you need to know before you start.

Are all the tools on DailyToolStack free?
Yes — every tool is completely free to use. There is no subscription, no account required, and no hidden charges. The site is supported by Google AdSense display advertising, which keeps tools free for everyone.
Do I need to create an account or sign up?
No. All standard tools work without creating an account. Just open the tool page and start using it immediately — no email, no password, no onboarding.
Are my files uploaded to a server?
Most DailyToolStack tools are designed to process files directly in your browser. Your files stay on your device and are not uploaded to any external server. Each tool page explains how it processes your data.
Do the AI tools require an API key?
Yes. The AI writing tools use your own OpenAI API key (BYOK — Bring Your Own Key). Your key is stored only in your browser's local storage and is never sent to DailyToolStack's servers.
What types of tools does DailyToolStack offer?
DailyToolStack offers three main categories: PDF tools (merge, split, compress, OCR, rotate, protect, watermark, and convert PDFs), AI writing tools (text improver, resume enhancer, SEO meta generator, study notes creator), and developer utilities (word counter, JSON formatter, QR code generator, slug generator, case converter, and image converter).
