Tool guide
What this tool does
Split PDF breaks one document into smaller PDFs. Cut it every N pages, define each output file as a range, save every page separately, or click thumbnails to choose where each part ends, then download the parts individually or as a ZIP.
Large PDFs are awkward to share. Email services commonly cap attachments at around 20 to 25 MB, upload forms ask for one document per field, and a 200-page scan often contains several unrelated letters. Splitting lets you send only the part that matters and keep each piece small.
The tool reads your PDF with pdf.js for previews and uses pdf-lib to copy the chosen pages into new documents. Because pages are copied rather than re-rendered, every part keeps the original text, fonts and image quality. All processing happens on your device, and the parts are offered as separate downloads plus a single ZIP archive.
How to use Split PDF
- Drop a PDF onto the upload area. The page count appears next to the file name.
- Choose a split method: Every N pages, Custom ranges, Every page or Pick on thumbnails.
- For custom ranges, write one output file per line, for example 1-3 on the first line and 4-10 on the second.
- For the visual method, click the last page of each part; a Split after badge marks your cut points.
- Check the Plan panel, which lists how many files will be created and their page ranges.
- Press Split PDF, then download parts individually or use Download all (ZIP).
Tips for better results
- A single line can combine ranges, such as 1-2, 9, which is useful for pairing a cover page with a later section.
- Choose the name-pages-1-3.pdf naming style when recipients need to know which pages each file contains.
- Every N pages with N set to 2 is a quick way to separate a batch of two-page forms scanned in one pass.
- Ranges may overlap, so the same page can appear in more than one output file if needed.
Common use cases
- Separating a batch scan of many letters into one PDF per letter.
- Sending a single chapter of a long report instead of the whole document.
- Breaking a large file into parts that fit under an email attachment limit.
- Extracting each payslip from a year-long payroll export into its own file.
Common mistakes to avoid
- Entering a page beyond the end of the document; the plan shows an error naming the valid range before anything is produced.
- Expecting split parts to keep bookmarks and form fields; only the page content and annotations attached to those pages are copied.
- Splitting encrypted PDFs, which cannot be rewritten until the password or permission lock is removed.
Frequently asked questions
How do I split a PDF into single pages?
Choose Every page as the split method and press Split PDF. You get one file per page, each named with its position, and a ZIP containing all of them.
Does splitting reduce quality?
No. Each page is copied into the new file exactly as it was, so text stays selectable and images keep their original resolution.
Why are the parts together larger than the original?
Shared resources such as embedded fonts are stored once in the original but must be repeated in every part that uses them, so the total size of all parts can exceed the source file.
Can I split a password-protected PDF?
Not directly. Encrypted files cannot be rewritten in the browser, so open the file in the app that created it, remove the protection, and then split it here.
