Stop Wasting Hours on Document Prep.
Meet the ultimate cloud-based app to merge, split, collate, bundle, and automate your files.
Designed for busy admins, educators, print shops, and professionals who just want to hit “Print” and move on with their day.
Collate (Combine) Pages Tool
The Problem
You need to bundle a dozen files from different clients into one clean presentation. Or maybe you’re struggling to combine a PDF with a JPG for a class report, or you’re completely at a loss for how to attach a 2-page cover form to a massive 50-page contract.
The Solution
Bring order to the chaos. Upload pages from completely different files (PDFs, JPEGs, and PNGs) and seamlessly drag-and-drop them into one clean, continuous, multi-page document.
It is the perfect tool for building complete legal packets, real estate bundles, or weekly lesson plans. You can easily duplicate pages, reorganize the order, or combine it with files you created in our Merge Tool for the ultimate document bundling experience.
The PDF Splitter Tool
The Problem
You’re stuck with a massive multi-page PDF, but you only need a specific chapter, a single invoice, or a handful of pages to share. Sending the whole file is bulky, confusing, and often unprofessional.
The Solution
Take control of your documents. Our splitter lets you break a multi-page PDF into the exact pages you need. Extract page ranges, remove unwanted content, or download every page as an individual PDF with a single click.
Need to reorganize? Send your extracted pages straight to the Collate Tool to reorder, trim, and reuse content from large files in a brand new bundle.
Merge (Imposition) Tool
The Problem
You have a hundred different files (stickers, tags, flashcards, images, business cards) and you need to impose them for printing without waste. Oh, and you need different quantities of each.
The Solution
The Merge Tool automatically arranges multiple files onto a single sheet. Upload your PDF, JPG or PNG files by drag and drop in the browser, or connect via FTP for larger batches. Choose a system template or create your own, set the sheet size, item size, margins and bleed, then merge everything in N-up, step and repeat or cut and stack formats.
Have multiple shapes and sizes to merge? Use the packable setting to fit them efficiently onto the sheet. Need it to run without anyone touching it? Use our API for hands-off automation and hook it into your existing workflow.
Mail Merge & Form Filler Tool
The Problem
Manually typing out hundreds of personalized envelopes, client letters, student certificates, forms, invoices, or mailing labels is soul crushing, error prone busywork.
The Solution
Upload a CSV file with your data and a base PDF or JPG file, and File Splice instantly creates a new personalized document for every single row. Handle massive list mailings and high volume PDF form filling in seconds, without the manual work.
Want print-ready sheets? You can automatically combine this with the Merge Tool to impose your mail merge output N-up or in a cut and stack layout at the exact same time you create it, giving you finished files in a single workflow.
Add Pages to PDF Tool
The Problem
You have a 100-page document and need to insert a cover sheet, divider, slip sheet, or specific instruction page every 5 pages. Manually splitting and re-combining the file is a recipe for a headache and lost afternoon.
The Solution
Automate your document assembly. Upload your main PDF and the page you want to insert (PDF, JPG, or PNG), then choose your frequency. You can insert your page before every page, or every X pages, and even control how many times the insert repeats.
It’s the perfect way to build training manuals, branded packets, and organized binders instantly without the manual labor.
Built for the Way You Work
From university classrooms to high-volume print shops, File Splice is the “Swiss Army Knife” for anyone who organizes and handles PDFs, forms and files.
Offices & Operations
Bundle invoices, statements, contracts, and reports into clean multi-page PDFs. Split and reorganize large files so each client, project, or department gets exactly the pages they need.

Frequently Asked Questions
Do I need Adobe Acrobat to split or merge my PDFs?
No. File Splice is a completely cloud-based alternative. You can split, merge, and collate your documents directly in your web browser without installing any heavy software or paying for expensive Adobe subscriptions.
Can I combine different file types like JPEGs and PDFs together?
Yes! One of our most popular features is the ability to upload a mix of PDFs, JPEGs, and PNGs. Our Collate and Merge tools handle these different formats seamlessly, allowing you to output them into one unified, high-quality PDF.
How does the “Add Pages” frequency tool work?
This tool automates the manual task of inserting slip sheets or dividers. You simply upload your main file and your insert page, then tell File Splice to insert it “every X pages.” The app handles the rest, building your entire assembly in seconds.
Is there a limit to how many files I can Mail Merge at once?
File Splice is built for high-volume production. Whether you are generating 10 personalized certificates or 10,000 mailing labels via CSV, our system processes the data in the cloud so your computer doesn’t lag or crash.
Does File Splice support Cut and Stack imposition?
Yes. Along with N-Up and Step & Repeat, we offer a dedicated Cut and Stack layout. This is essential for print shops producing numbered tickets, booklets, or any project that needs to remain in a specific order after being cut on a guillotine.
