Batch on folders
Every tool can run on a list of files or a whole folder: an error on one file does not stop the others.

Tools
The Tools module gathers the practical everyday utilities: remove or apply a PDF password, sanitize it from active content, strip metadata from an image and rename a file to its hash. All locally, with no online services.
What it does
What the Tools module does
PDF password
Removes protection from a PDF or encrypts it with a password (AES-128) for opening and permissions.
Sanitize PDF
Removes metadata (author/creator) and active content (JavaScript, OpenAction, attachments) from the PDF.
Deep clean (CDR)
Rebuilds the PDF, disarms active content, discards embedded font programs remapping fonts to standard ones (recovering the text where the encoding allows) and neutralises JBIG2 and JPX images, the class of the FORCEDENTRY attack. The cleaned copy is created next to the original, which is left untouched, and the limits are declared in the summary: safety at the expense of typographic fidelity.
Straighten pages
For pages photographed in perspective or scanned askew, Probatio finds the sheet or the slope of the lines by itself; page by page you choose between automatic, no correction and corners by hand. The result is a derived copy with the transformation log next to it (.raddrizzamento.json): source file with its hash, hash of the copy, transformation of every page. The source PDF is not touched.
Strip image metadata
Removes EXIF/GPS/XMP/IPTC from JPEG/PNG without re-compression (lossless).
Rename by hash
Renames the file to its SHA-256 hash, for a tamper-evident name.
Step by step
How it works
- Pick the utility and drop the file (PDF or image).
- Set any parameters (password) and get the processed file.
FAQ
Frequently asked questions
How do I remove a PDF password?
Drop the PDF into the «Remove password» tool and get an unprotected copy; you can also encrypt a PDF with a password (AES-128) for opening and permissions.
What does "sanitizing" a PDF mean?
It removes metadata (author/creator) and potentially risky active content — JavaScript, OpenAction, attachments — leaving the visual document intact.
Can I strip EXIF/GPS from a photo?
Yes: the tool removes EXIF, GPS, XMP and IPTC from JPEG and PNG without re-compression (lossless), useful to publish an image without revealing device and location.
