Document restoration and electronic signatures

Readable documents.
Nothing invented.

Doc4Desk Suite brings document restoration and electronic signatures into one workspace. Improve readability, review the result and prepare a request on a fixed PDF version. The original remains untouched.

Secure accessExplore capabilities

Built for files that leave no room for error

Conservative tools that improve readability without changing content. This public page never shows client information.

Untouched original

Each file is kept byte for byte with its SHA-256 fingerprint; processed versions are stored separately.

Bounded adjustments

Rotation, limited brightness and contrast, color, grayscale or black and white, on letter, A4 or original size.

JPEG, PNG and PDF

Up to 30 pages and 20 MB per batch, including password-protected PDFs; the password is never stored.

Required review

Page-by-page comparison of original and result, with quality warnings before download.

Signature preparation

Assign recipients and fields to the reviewed PDF. Invitation delivery requires firm configuration.

Final PDF and evidence

Signatures are saved before final files are generated. Failed generation can be retried.
