Description
File Splice is a simple, lightweight imposition tool designed to merge and arrange your files directly inside WordPress. Whether you are dealing with PDFs, JPGs, or PNGs, File Splice helps you easily turn your designs and media files into professional, print-ready sheets.
To handle the heavy lifting of high-performance file processing, merging, and imposition generation, this plugin connects to the external File Splice API.
Features
- Easy Imposition: Create print-ready sheets directly from your WordPress dashboard.
- Sheet Preview: See a to-scale preview of the press sheet, and how many files fit on it, before you spend a build.
- File Merging: Combine multiple files into a single document effortlessly.
- Per-File Quantities: Set how many of each design you need, and see how many sheets that works out to.
- Format Support: Works seamlessly with PDF, JPG, and PNG files.
- Fast Processing: Uses the File Splice API to ensure files are merged quickly and securely without overloading your web server.
Requires a File Splice Account
This plugin is a front end for the File Splice service and does nothing on its own. It requires an active File Splice account and an API key, which is issued to paid accounts. See the pricing page for current plans.
Templates are created and edited in your File Splice account rather than in WordPress. The plugin reads the templates on your account and links you there to manage them.
Important Privacy and Third-Party Service Disclosure
This plugin relies on the external File Splice service, operated by Liquid Designs, LLC, to process and merge your files. Imposition cannot be performed locally. It happens on the File Splice servers.
Nothing is sent anywhere until you enter an API key. With no key saved in the plugin settings, the plugin makes no external requests at all.
Once a key is saved, the plugin contacts https://app.filesplice.com when you:
- Test the connection, or load the list of templates on your account
- Load the details of a template you select
- Upload a file, which transmits the file itself
- List or remove the files attached to a template
- Start a build, or check whether a build has finished
What is transmitted:
- Your File Splice API key, on every request, to identify your account
- The files you choose to upload, in full
- The filenames and quantities you set when you start a build
Your WordPress content, users, and site data are never transmitted. The plugin only sends what you explicitly give it.
Finished sheets are returned as links to Amazon S3. Clicking Download opens that link and fetches the file directly from S3.

FAQ
-
Does this plugin send data to a third-party server?
-
Yes. To perform file imposition and merging, your uploaded files are sent to the File Splice API at
app.filesplice.com. Your API key is sent with every request to identify your account. Nothing is sent until you save an API key in the plugin settings. -
Do I need a paid account?
-
Yes. API keys are issued to paid File Splice accounts. The plugin will not function without one.
-
Where can I read your privacy policy and terms?
-
Data handling is described on our Security and Privacy Page, and the terms of the service are on our Terms and Conditions Page.
-
What file types can I upload?
-
PDF, JPG, and PNG, up to 50 MB each. File types are verified by reading the file itself rather than trusting the extension. If your server’s PHP upload limit is lower than 50 MB, the plugin uses that lower limit and tells you what it is.
-
Can I create templates from WordPress?
-
Not in this version. Templates are created and edited in your File Splice account, and the plugin links you straight there.
-
Why do some files have no thumbnail?
-
Thumbnails are rendered by your browser at the moment you upload a file. A file uploaded through the File Splice web app never passed through WordPress, so there is nothing to render, and the row shows the file extension instead. Encrypted or damaged PDFs also produce no thumbnail. Neither case prevents the file from being uploaded or imposed.
-
How long are my files kept?
-
File Splice automatically and permanently deletes uploaded files 14 days after upload, so download your finished sheets within that window. Files uploaded through public pages are deleted within 24 hours. See the Terms and Conditions for details.
-
The build says it is waiting for File Splice to finish processing a file. Why?
-
File Splice processes each file after upload, which takes a few seconds and longer for larger files. If you start a build before that finishes, the plugin waits and retries until the file is ready.
-
Does this work with WooCommerce?
-
Not in this version. This release is an admin tool.
