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.
Does rotating reduce quality?
No. ZapDoc changes each page’s rotation setting; the page content is not re-rendered or re-compressed.
Can I rotate only some pages?
Yes. Enter pages like “2, 5-7”, or leave the field empty to rotate every page.
Is ZapDoc free?
Yes. There is no sign-up, no watermark and no daily limit. ZapDoc is open source under the MIT license.
