Upload the file
Upload the picture, screenshot or PDF you want to sign and time stamp. Just drag and drop.
Add extra fields
Optionally, you may add some extra fields for signing, such as your name, location, reason and contact info. All this data will be signed and appended to the file’s metadata. Additionally, you can add a watermark to make visible the signature. This watermark will contain a checksum for retrieving the time stamp.
