Frequently asked questions
Are my files uploaded anywhere?
No. ZapDoc 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.
Can I reorder pages while extracting?
Yes. Pages come out in the order you type them, so “3, 1-2” puts page 3 first.
What happens to bookmarks and form fields?
Bookmarks are kept. If a bookmark points to a page you did not keep, ZapDoc warns you. Form fields on removed pages are removed cleanly.
Is ZapDoc free?
Yes. There is no sign-up, no watermark and no daily limit. ZapDoc is open source under the MIT license.
