Frequently asked questions
Are my files uploaded anywhere?
No. Fizzdoc does the work inside your browser tab, using open-source engines compiled to WebAssembly and JavaScript. Your file is read from your device, processed locally, and the result is saved straight back to your device. You can check this yourself: open your browser’s developer tools, go to the Network tab, and run a job — no request carries your file.
Will the animation keep its timing?
Yes. Every frame keeps its own delay, and the new GIF loops like the original.
Why are the edges a little sharper than in a PNG?
A GIF pixel can only be fully see-through or fully solid, so soft edges can’t be kept on a clear background. For soft edges, pick a colour or a photo behind instead of “None”.
Is Fizzdoc free?
Yes, and it stays free: no sign-up, no watermark, no daily limit and no premium tier. Fizzdoc is open source under the Apache-2.0 license, so anyone can run their own copy.
