Split PDF Free Online – Separate PDF Pages into Files
Split PDF is a free in-browser tool that separates a PDF into multiple files without uploading your file. Split every page, extract specific pages, or break the document into custom page ranges, then download the results individually or as a ZIP — all processed locally on your device.
Why Use TryDocsy PDF Splitter?
No Upload Required
All splitting happens in your browser. Your PDFs never leave your device.
4 Split Modes
Split all pages, by ranges, every N pages, or extract specific pages.
ZIP Download
Download all split files at once as a convenient ZIP archive.
No Account Needed
No sign-up, no email, no tracking. Just open and split.
Individual Downloads
Download each split PDF file individually if needed.
Free, up to 100 MB
No watermarks and no hidden fees; the uploader accepts PDFs up to 100 MB.
Split PDF takes one PDF apart in your browser and hands you back either a set of smaller PDFs or a single PDF holding just the pages you picked. The file is read with the @cantoo/pdf-lib library inside the page, so nothing is uploaded; the moment you choose a file the tool opens it and shows its real page count next to the file name, which is also the first sign that the PDF is readable at all.
There are four ways to cut: Split All Pages (one file per page), Custom Ranges (one file per range you type), Every N Pages (equal chunks) and Extract Pages (a single file built from the page numbers you list). Pages are copied object-by-object rather than re-drawn, so text stays real text and images keep their original resolution — but each result is a brand-new document, so document-level extras such as bookmarks and a fillable form definition do not travel with the pages. If you only want to throw a few pages away and keep one file, /pdf/delete-pages is the shorter route.
How it works
1. Drop the PDF in
The upload box reads “Drop PDF file here” and accepts a single .pdf up to 100 MB. The tool then opens the document immediately: a protected file stops here with a message pointing you at the PDF Unlock tool, and a damaged one stops with “Failed to load PDF. The file may be corrupted.”
2. Pick how to split
Four cards appear under “How do you want to split?” — Split All Pages, Custom Ranges, Every N Pages and Extract Pages. The first card names the exact number of files it will produce, because the page count is already known.
3. Type the pages you want
Custom Ranges takes a comma-separated list such as 1-3, 5-7, 9. Every N Pages takes a single number (it starts at 2) and tells you how many files that makes. Extract Pages takes individual page numbers such as 1, 3, 5, 7.
4. Split, then download
Press “Split PDF”. One output file gives you a plain “Download PDF” button; several give you “Download All as ZIP” with the archive size shown, plus a scrollable list underneath so you can grab a single piece on its own.
When you'd use it
Pulling one certificate out of a scanned bundle
Scanned mark sheets, degree certificates and experience letters often live in one long PDF. Extract Pages pulls the two or three sheets an employer asked for into one small file, leaving the rest of the bundle untouched.
Getting under a portal's upload cap
When a submission form refuses a 40-page document, Every N Pages breaks it into predictable chunks of five or ten pages that each upload comfortably, and the file names carry the page range so you can label the uploads correctly.
Sending one chapter to one person
A contract annexure, a single chapter of notes or one property document inside a compiled deed can be cut out with Custom Ranges, so the person you send it to never receives the pages that were not meant for them.
Rebuilding a document in a different order
Splitting every page and then dropping the pieces you want into /pdf/merge is a practical way to rebuild a document in a new sequence when the original was assembled wrongly.
What each mode actually produces
Split All Pages loops over the whole document and writes one PDF per page, named page-001.pdf, page-002.pdf and so on, zero-padded to three digits so they sort correctly in any file manager. A 30-page document therefore becomes 30 files, which is why the ZIP button exists.
Custom Ranges produces one file per comma-separated entry, named after the range it came from, for example split-1-pages-1-3.pdf. A range that is only a single number is allowed, so 1-3, 5 gives you a three-page file and a one-page file. Every N Pages walks the document in fixed strides and names each piece after the pages it holds, such as part-01-pages-1-5.pdf.
Extract Pages is the odd one out: every page number you list ends up in one file called extracted-pages.pdf, in the order you typed them. Listing 5, 1 really does put page 5 first, which is occasionally useful and occasionally a surprise.
What survives the cut
Each output is built by creating an empty PDF and copying the page objects you asked for into it, so the page keeps its own size, its vector text, its fonts and its images exactly as they were. Nothing is rasterised and nothing is recompressed, which is why splitting is lossless and why a single extracted page can still be large if the original page carried a high-resolution scan.
What does not come across is anything stored at document level rather than on the page: an outline of bookmarks, and the form definition that makes fields fillable. The pdf-lib documentation makes the same point about copying a whole document, noting that acroforms and outlines are not carried over. If the PDF is a form you have already filled in, run it through /pdf/flatten first so the answers become part of the page artwork, then split it.
When the page numbers do not behave
The range parser is forgiving in specific ways. A backwards range like 7-3 is silently turned the right way round, and a range that runs past the end of the document is trimmed to the last real page, so 20-99 on a 24-page file gives you pages 20 to 24. Entries that are not numbers at all are skipped rather than reported.
If nothing at all matches — every number you typed is outside the document, say — the tool stops with “No pages matched your selection. Please check your page numbers or ranges and try again.” Page numbers here are the positions in the PDF, counting the cover as page 1, which is not always the number printed on the page itself.
Very large documents are limited by your device rather than by a rule in the tool: each output file is assembled in memory and then zipped in the same tab, so splitting a 100 MB scanned book into hundreds of single pages is slower on a phone than on a laptop. Splitting into a handful of ranges is far lighter than splitting every page.
Frequently asked questions
Do I always get a ZIP file?
Only when the split produces more than one file. Extract Pages makes a single PDF and offers a direct download; the other three modes usually make several, so you get a ZIP button plus a list for downloading pieces individually.
Can I split a password-protected PDF?
No. The file is opened as soon as you select it, and a protected one is turned away with a message telling you to unlock it first with the PDF Unlock tool. Remove the password there, then split the unlocked copy.
Will the split pages lose quality?
No. Pages are copied as objects into a new document rather than re-rendered, so text remains selectable and images keep their original resolution. The pieces added together are roughly the size of the original.
Why is my one-page PDF still a few megabytes?
Because the page kept everything it originally carried, including a full-resolution scan or an embedded font set. Splitting never recompresses anything — run the result through /pdf/compress if you need it smaller.
Do bookmarks and form fields survive?
No. Each output file starts as an empty document that receives only the copied pages, so the bookmark outline and the document's fillable-form definition are left behind. Flatten a filled form before splitting if the answers must stay visible.
What is the largest PDF this handles?
The uploader stops anything above 100 MB at the moment you choose the file. Below that the practical ceiling is your device's memory, since every output file is built inside the browser tab.
Are pages numbered the way they are printed?
No. Every mode counts from the first page of the file, so a report whose printed page 1 comes after a cover and a contents sheet is page 3 here. Check the page count shown next to the file name if you are unsure.
