No, every tool is open and free to use — pick a suite and start immediately.
No installation is required. All WizzyTools operate entirely in your web browser and are fully compatible with modern browsers on Windows, Mac, Linux, iOS, and Android.
Dev tools run entirely in your browser. Where a tool needs server processing, any uploaded file is deleted automatically within 30–60 minutes and is never used for training.
Yes. The vast majority of our tools process your data entirely locally in your web browser. For tools that require server-side processing, your files are securely processed and automatically deleted from our servers within 30-60 minutes. They are never used for training or shared with third parties.
Each suite (PDF, Image, QR, Dev) ships and scales independently, but they all share this same design, header, and footer.
There are no hard usage limits on our free tier. You can use our utilities as many times as you need. Extremely large files or complex operations might take longer to process, but there are no paywalls for standard usage.
