Questions about create zip
How much smaller will the ZIP be?
It depends entirely on the contents. Text, code and documents often compress to a third of their size or less. Photos, video and audio are already compressed and will barely shrink, so the ZIP mainly serves to bundle them into one file.
Are folder structures preserved?
Yes. Dropping a folder keeps its paths inside the archive, so extracting it recreates the same layout.
Can I password protect the ZIP?
Legacy ZIP encryption is weak enough that it is not worth offering. For genuinely sensitive files use full file encryption rather than relying on an archive password.
Are my files uploaded to a server?
No. The whole thing runs inside the browser tab you already have open. Your file is read straight from your own disk, worked on there, and handed back as a download. Nothing is sent anywhere, nothing is stored, and there is no account and no queue.
Is there a file size limit?
There is no server-side limit because there is no server. The practical ceiling is your device memory, since the file and its output both have to fit in the tab. Files up to a few hundred megabytes are usually fine on a desktop machine, while phones and older laptops will struggle sooner. If a large file fails, close other tabs and try again.
Does it work offline?
Yes, once the page has loaded once. The engine is cached by the browser, so you can turn off your connection, reload the page and keep working. That is a useful side effect of doing the processing locally rather than a separate offline mode you have to enable.
