Local File Checksum Plugin for Elementor
Let visitors check that a file they downloaded is identical to yours by computing its SHA-256 checksum in the browser and comparing it with the one you publish.

Check a real file in your browser
These are the actual published outputs of the widget set up with the checksum of a sample PDF: the default checker, a styled button and a checksum-only version. Choose any file to try it; nothing is uploaded.

Local file checksum controls in Elementor
Content › File and expected checksum takes the SHA-256 you publish and the largest file size to read. Labels and messages sets the button texts, result labels, match and mismatch messages and the explanation under the button, with options to show the file name and the expected checksum. The Style tab covers the button with states, border, radius, padding and icon, the result and verdict text, and spacing.
03 / Website use cases
Where to use local file checksum
When you offer software, firmware or documents for download, careful users want to confirm the file arrived intact and unchanged, but checksum tools mean a command line most visitors never use. Local file checksum adds a button that reads the chosen file on the visitor's device, computes its SHA-256 and says whether it matches the checksum you publish.
Document distribution
Show that a contract or report is unchanged from the published version.
Data sets
Help researchers verify a large data file downloaded completely.
04 / Installation and setup
How to add a file checksum check in Elementor
Start with Complementor installed and your license connected. Enable this module in the WordPress library, then configure it in Elementor.
Install Complementor, connect your license and enable Local file checksum in the Complementor library.
Compute your file's SHA-256, for example with sha256sum or Get-FileHash.
Add the widget next to the download and paste the checksum into Expected SHA-256.
Set the largest file size and the button text.
Publish, download your file and check it with the widget.

06 / Choose the right approach
Local file checksum and Elementor alternatives
Compare the existing Elementor workflow with this Complementor module before choosing your setup.
Command-line tools
sha256sum and Get-FileHash give the same result but most visitors never open a terminal.
Online checksum sites
Many upload the file to a server. This widget reads it locally and sends nothing.
07 / Requirements and compatibility
Local file checksum compatibility with Elementor
- Requires Elementor.
- SHA-256 only; one file at a time.
- Needs a secure (HTTPS) page.
Complementor uses classic Elementor APIs. Atomic-native controls are not implemented. Check your theme, cache and integrations on a staging site before release.
08 / Common setup problems
Troubleshoot local file checksum
Check these settings if the published page behaves differently from the editor.
Why is the button disabled?
The page is not served over HTTPS, or the browser lacks Web Crypto. Secure pages are required for in-browser hashing.
Why does a matching file say it does not match?
Check the expected value is the SHA-256 (64 characters) of the same file version, without spaces.
Why was my file not read?
It is larger than the Largest file setting. Raise it, up to the built-in cap.
Does a match prove the file is safe?
No. It shows the file is identical to the one the checksum came from, not that it is free of malware.
Local file checksum plugin questions
Does it need Elementor Pro?
No. It works with the free version of Elementor.
Is the file uploaded?
No. The file is read in the visitor's browser and never leaves their device.
Is it accessible?
Yes. The button is keyboard operable, progress and results are announced, and the checksum is selectable text.
Which algorithm does it use?
SHA-256, the most common checksum published for downloads.
Can I use it without an expected checksum?
Yes. It then shows the file's SHA-256 for visitors to compare themselves.
