No uploads. No watermarks. No size limits. Filoraio splits a PDF into smaller files by page ranges or every N pages — locally, in your browser, in seconds.
Filoraio runs the merge directly inside your browser using a small WebAssembly engine. Nothing is uploaded, nothing is queued, and you can verify it yourself — open your browser’s DevTools, switch to the Network tab, and watch it stay quiet.
They’re read into your browser’s memory through a standard file picker.
The merge runs locally — no request leaves your device while it processes.
The combined PDF lands in your downloads folder, the same way any other download would.
No upload bar, no progress spinner waiting on a server. Works offline once the page is loaded.
From drop to download takes a few seconds, even on a 500-page document — the work runs locally so there's no upload to wait on.
Drop a PDF on the picker or click to choose one. The tool reads its page count instantly so you can see what you're working with.
Pick page ranges (like 1-5, 8, 12-20) when you want specific sections, or pick every N pages when you want equal-sized chunks.
Press the split button. Each output PDF is built locally on your device — nothing is uploaded, queued, or processed on a server.
If you produced one file, it downloads as a PDF. If you produced several, they download as a single zip you can extract anywhere.
If you regularly receive long PDFs and need to share or archive only specific sections, this is the tool that pays for itself in clicks.
Pull just the relevant exhibit pages out of a 200-page disclosure bundle to send to opposing counsel.
Break a downloaded conference proceedings PDF into one file per paper so you can cite and store them individually.
Split a yearly bank statement PDF into twelve monthly files for cleaner client folders and faster review.
Cut a textbook chapter PDF into one file per section so students can download just what's assigned this week.
Separate a single multi-document scan into individual records — one file per form, intake sheet, or signed page.
Extract a single contract page or invoice from a longer compiled report before sending it to a client.
Three quick walkthroughs of the exact reasons people search for a way to break a PDF into pieces.
You received a 60-page deal package and only need to forward pages 12-18 (the executed contract) to your accountant. Drop the file in, type 12-18 into the range field, and you have a clean 7-page PDF in seconds.
Your bank gives you one PDF per year, each statement starting on a known page. Use ranges like 1-4, 5-8, 9-12, 13-16... or just pick "every 4 pages" and the tool produces twelve dated chunks ready to file.
The required reading for week 3 is pages 78-103 of a 400-page course PDF. Type 78-103 and you have a focused document to read on a tablet — no scrolling past 77 unrelated pages every session.
An office scanner produced one PDF containing four different forms back-to-back. List each form's page range as a comma-separated list and you get one PDF per form, packaged as a single zip download.
Four small habits that prevent the most common splitting mistakes — and turn a good split into a perfect one.
Visible page labels ("Chapter 3 starts on page 47") aren't always the same as the PDF's internal page index. If your splits land in the wrong place, scroll to the section in your viewer and use the index from the viewer's status bar.
Bank statements and report periods are usually fixed-page-per-period — perfect for fixed-mode splitting. Mixed-length chapters or contract sections need explicit ranges instead, otherwise content lands in the wrong file.
The range field accepts "1-5, 8, 12-20" — three outputs in one go. Use this when you need a couple of specific pages plus a range, rather than running the splitter twice.
Browsers occasionally block large zip downloads or fail mid-write on low-disk-space devices. Always confirm the extracted files open before clearing the original from your device.

| Multi-file delivery | Single zip download | Per-file or paid bundle |
Quick answers to the things people ask most often before using this tool.
Yes. There's no account, trial, daily quota, or watermark on the output. Filoraio is supported by ads on the page — never on your file. You can split as many PDFs, of any length, as you want.
No. The split runs entirely in your browser using a small WebAssembly library. Your PDF is read, processed, and saved without ever leaving the tab — which is why this works on confidential and offline files.
Comma-separated ranges and single pages, in any combination. "1-5, 8, 12-20" produces three output PDFs: pages 1-5, page 8 alone, and pages 12-20. Spaces are optional.
Page ranges let you pick specific sections by hand — useful for irregular splits like "chapters" or "contract pages". Every N pages produces equal-sized chunks automatically — useful when a document was assembled at a known page interval.
Yes. In the page-range field, just type the page number on its own (for example, 8). You can mix single pages and ranges in one request: 1-5, 8, 12-20.
Browsers block automatic downloads of multiple files in quick succession (the second prompt is treated as a popup). Bundling everything as one zip is a single, reliable download you can extract on any operating system.
Each output keeps the original page content unchanged, so file size is roughly proportional to the page count. If you want smaller files afterwards, run any of them through our Compress PDF tool — that's the right step for shrinking, not splitting.
Encrypted PDFs aren't supported directly — unlock them first. Run the file through our Unlock PDF tool (owner restrictions come off automatically, user-password files decrypt locally with your password), then drop the unlocked output here for splitting.
Open this page in Safari, tap the drop area, pick a PDF from the Files app, type your ranges, and tap Split. The single PDF or zip downloads directly to Files — no app store, no Apple ID, no install.
Open this page in Safari or Chrome, drop the PDF, type the ranges (or pick "every N pages"), and download the result. Preview can split too, but it's slower for irregular ranges and can't bundle outputs as a zip.
If a range goes past the end of the document (e.g. 90-100 on an 80-page PDF), older browsers used to silently emit a zero-page output. Filoraio now refuses ranges past the end with a clear error — so empty outputs shouldn't happen. If you see one, please report it with the source file size and your browser version.
External hyperlinks (URLs) remain clickable in every output. Bookmarks pointing to pages outside that output's range are dropped automatically — keeping them would create dangling links. Internal cross-references inside a single output range are preserved.
Yes — there's no hard cap. The zip generation does scale with output count, so 200+ outputs takes longer than 5; in practice the bottleneck is your device's RAM, not Filoraio. If you regularly split into hundreds of files, run the operation on a desktop rather than a phone.
Page numbers in the field refer to the PDF's internal page index (1-based). That's usually the same as the visible page label, but documents with front matter ("page i, ii, iii") sometimes have a label/index mismatch. If your splits land in the wrong place, count from page 1 of the file itself, not the printed page number.
Tools picked because they pair naturally with the one above — the next step in a typical PDF workflow.
