Is DailyTooler free to use?

Yes. Every tool is free, with no account, no sign-up, and no paywall. Just open a tool and use it.

How long are uploaded files kept?

Most server-backed tools, such as PDF merging or CSV conversion, process your file in memory and return the result directly, without ever writing it to disk. Image tools that generate a downloadable file, such as the WebP converter, store that output only long enough to serve the download link, typically up to 24 hours, and then delete it automatically.

How do I find a specific tool quickly?

Press Ctrl+K (or Cmd+K on a Mac) anywhere on the site to open the tool search and jump straight to any tool by name.

Can I use DailyTooler on my phone?

Yes. The site is fully responsive, so every tool works on a phone or tablet as well as a desktop browser.

What is DailyTooler?

DailyTooler is a growing collection of small, focused web tools for everyday work. Each tool does one job well, whether that is converting a color format, resizing an image, or building a cron expression. There is no sign-up, no bloated wizard, and no upsell in the middle of a task. Open a tool, use it, and get back to work.

The site is organized into simple categories: Text, Data, Marketing, Developer, Security, PDF, Images, Crypto, and Design. Each category groups tools that solve related problems, so a developer debugging an ObjectId or a marketer building a campaign URL can find the right tool in a couple of clicks. A command palette also helps: press Ctrl+K, or Cmd+K on a Mac, to jump straight to any tool by name.

How the tools work

Not every tool works the same way behind the scenes, and that is intentional. Purely mechanical tasks, like converting case, counting words, or encoding a URL, run entirely in your browser using plain JavaScript. Nothing you type in those tools is sent anywhere, so the result appears instantly and your input never leaves your device.

Security-sensitive tools follow the same rule for a stronger reason. The password generator and the RSA key pair generator both use your browser's built-in Web Crypto API to create random values and keys locally. A generated password or private key is never transmitted over the network, not even to DailyTooler's own servers.

Some tools genuinely need a server. Resizing a large image, converting a PDF to images, or checking a cron expression against a mature scheduling library is easier and more reliable with a small, purpose-built backend than with a hand-rolled reimplementation in the browser. Those requests go to DailyTooler's own API, the uploaded file or text is processed, and the result is returned without being kept longer than necessary.

Who uses DailyTooler

The tools here are built for the people who reach for them most often. Developers use DailyTooler for a quick UUID, hash, or ObjectId. Marketers use it to build tracked campaign URLs. Writers use it to check a word count or estimated reading time. Designers use it to convert a color between HEX, RGB, and HSL. If a small tool would solve your problem faster than opening a heavy desktop app, DailyTooler is built for that moment.

New tools are added regularly, usually because a real task needed one and none of the existing options felt right. If a tool you rely on elsewhere is missing here, it is likely already on the list to build next.
