Frequently asked questions
Are these online tools really free?
Yes. Every tool is completely free to use, with no account, no watermarks, no trial, and no usage limits. There is nothing to pay for and nothing to unlock.
Do my files or text get uploaded to a server?
No. Every tool runs locally in your browser using your own device. Your images and text are never uploaded, stored, or sent anywhere, which makes these tools private and safe to use with sensitive content.
Do I need to sign up, register, or install anything?
No sign-up, no registration, and no install. There is no app to download and no extension to add. Open a tool in any modern browser and start using it right away.
What kinds of free tools can I find here?
A growing catalog of everyday text and image utilities, plus PDF and video tools, and tools for developers, designers, converting between formats, working with dates and time, and handling unicode. New tools are added regularly based on what people ask for.
Do the tools work on mobile, and which browsers are supported?
They work on any modern browser on desktop, tablet, or phone, including Chrome, Safari, Firefox, and Edge. Because everything runs in the browser, there is nothing to install on your device.
Do I need an internet connection to use the tools?
You need a connection to load a tool page the first time. After that, most tools keep working even if your connection drops, because the processing happens on your device rather than on a server.
Is there a limit on file size or how many times I can use a tool?
There are no usage limits and no daily caps. Because processing happens on your own device, very large files are limited only by your device memory rather than by an upload cap or a paid tier.
Will compressing or converting a file reduce its quality?
Only as much as you choose. Tools that change a file, such as image compression or format conversion, let you control the trade-off between size and quality, and you can preview the result before you download it.
Is it safe to use these tools with private or sensitive files?
Yes. Since your files never leave your browser, nothing is transmitted to a server, logged, or shared. That makes these tools a private alternative to sites that upload your files to process them.
Do you store or track the files and text I process?
No. Because nothing is uploaded, there is nothing for us to store. We do not keep your files or text, and there is no account system tracking what you do.
Can I use these tools for commercial or client work?
Yes. The tools are free for personal and commercial use, with no licensing step and no attribution required. Use them for client work, internal projects, or anything else.
How often are new tools added?
New tools are added regularly. The catalog focuses on the most-requested everyday tasks and grows over time, so it is worth checking back or suggesting what you need.
A tool I need is missing. Can I request it?
Yes. Use the suggest a tool page to tell us what you need. We prioritize the most requested tools, and the catalog grows over time.
