Split a PDF packet into pages you can check
A packet is not one thought
Split when the pages need different recipients or different folders. A three-page packet on the split page becomes three PDFs in a ZIP, named in order. That is useful for “send page 2 to the printer and keep page 3.” It is a poor way to hide a page. The other pages still exist in the original, which you should keep, and a split does not redact the page you left out of the ZIP. If the goal is to remove an account number, use redact and then test whether the number can still be copied. If the goal is one file in a new order, use merge.
Open every file in the ZIP before you rename them. The default names are dull so they do not pretend to know what the page is. After you have looked, rename page-002.pdf to something you will recognize next month. A blank extract usually means the source had a blank page. Do not email the whole ZIP when only one page was requested. Narrow the range. The browser builds the ZIP. NexTool does not receive the packet. A very long scan can fail when memory runs out. Split a shorter range, or use a machine with more free memory, rather than uploading the packet to finish the job.
Images of pages are a third choice
PDF to images gives you pictures, not small PDFs. Use it when a slide or a chat app wants a JPG. Do not use it when the recipient must have a real PDF with the original page size. Pictures are easy to recompress by accident in a messenger. If you need both a single page PDF and a preview image, export them as two jobs and label them. The sample brief has two pages, so the image ZIP should have two pictures. Count them.
Name the pieces after you have seen them
The ZIP from split uses dull names such as page-001.pdf so the tool does not pretend to know that a page is an invoice. Open each file. A blank piece usually means the source had a blank page. Rename only after the picture matches the name you are about to type. If someone asked for one page, send that page, not the ZIP of the whole packet. Narrow the range and export again. The original packet remains the file you started with, because the split is a copy made in the browser. NexTool does not receive the packet and cannot mail the pieces back to you if you close the tab before the download finishes. A very long scan can fail for memory. Shorten the range or use a machine with more free RAM instead of uploading the file to finish the job.
Send the page, keep the packet
After the names are right, send only the pages that were requested and keep the ZIP until the recipient confirms they can open them. A split does not shrink the pictures inside a scan. If the pieces are still too large to mail, compress each piece from its own file, or compress the original first and then split that smaller copy, and say which order you used.
