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.
Does editing lower the quality?
No more than saving does. Every change is drawn again from your original photo, so edits never pile up, and the photo is saved at its full size unless you pick a smaller one. JPG and WebP are saved at high quality; PNG is lossless.
Is the location from my phone photo kept?
No. The saved photo is a new file with only the picture in it, so hidden details such as the GPS location, the date and the phone model are left out.
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.
