Frequently Asked Questions

Redacting sensitive information is pointless if you upload the raw file to a cloud server. RunOnLocal redacts entirely on your machine for true security.

Is my data private and secure?

Yes, absolutely 100%. By utilizing modern local browser technologies, we process your files directly on your computer or phone. No servers, no uploads, no compromises.

How fast is the processing?

Because there are no uploads or downloads to a remote server, processing is virtually instant. Even large PDF files are processed in milliseconds without eating up your network bandwidth.

Can the black boxes be removed?

No. When you apply the redaction, we completely destroy the underlying text data so it cannot be copied, searched, or recovered.

Are there any limits or watermarks?

Enjoy completely unrestricted access to the tool! You can use it an unlimited number of times for free. We never artificially cap your file sizes, demand subscriptions, or ruin your final documents with unwanted branding or watermarks.
