Seal files

Choose files or a whole folder. This page fingerprints each file, mixes in a random number that stays with you, and sends Pith only the combined number. You'll get a public receipt and a seal file to keep with the originals.

Drop files here, or choose them.

Keep an encrypted copy on Arweave, a permanent public blockchain If you lose every device, 24 recovery words bring back the files and their seal file. Nobody else can read the copy, and neither you nor Pith has to store it. Free up to 100 KB per copy after compression; Seal Pro pays for copies up to 10 MB.
