Frequently asked questions
- How are the parts decided?
- Pages are kept in order and added to a part until the next page would take it over the limit. Then a new part starts.
- What if one page is bigger than the limit?
- A single page can't be split, so it becomes its own part and you are told. Try Compress PDF on the original first.
- Will the parts be exactly the limit size?
- No. Each part is at or under the limit, usually a little below it.
- Are my files uploaded anywhere?
- No. This tool runs entirely in your browser, so your file never leaves your device.
