File Splice Tools & Features
Merge (Imposition) Tool
This is the tool that lays out multiple files on a sheet and creates a print ready PDF.
How it works
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. From combining two simple pages to hundreds of different files for printing or production, the Merge Tool is built for real world jobs.
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. You can also try a few of the interactive demos to see typical jobs from start to finish.

Mail Merge Tool
This tool handles both classic mail merge and high volume PDF form filling.
How it works
Upload a CSV file with your data and a PDF or JPG template, and File Splice creates a new set of documents—one for each row in the spreadsheet. Each letter, form or label is personalized with the right name, address or other variable fields, so you can handle large list mailings and bulk form filling without manual work.
You can use the mail merge tool on its own, or combine it with the merge (imposition) tool to impose your mail merge output N-up or in cut and stack format at the same time you create it, giving you print ready sheets in a single workflow.
Add Pages to PDF Tool
This tool makes it easy to insert cover sheets, slip sheets, photos, images or other pages into an existing multi-page PDF.
How it works
Upload the main PDF you want to work with, then upload a single page you want to insert, this can be a PDF, JPEG or PNG. Choose whether to place that page in front of every page, or every X pages, and how many times to repeat it. File Splice builds a new PDF with your insert pages placed exactly where you need them.
