Traceable sharing

Make every shared copy traceable

Turn on a team policy, or mark a single document in a data room, and every image, PDF and video someone downloads through a link gets the downloader’s name, email and date printed diagonally into the file. On view-only links, a watermark is tiled over the preview.

Mengapa upload.am

Two ways to make copies traceable

Stamp inside the file

The stamp is part of the downloaded file, so it cannot be removed by closing a browser overlay.

Watermark on view-only

The recipient’s email, or their IP address and the time, is tiled over the preview.

Per document or per team

A team policy stamps everything, or you mark single documents in a data room.

A deterrent, not magic

It discourages leaks and shows the source. It cannot stop someone photographing a screen.

upload.am vs. layanan penyimpanan file biasa

Kebanyakan penyimpanan file gratis hanya memberi Anda satu hal: sebuah tautan. upload.am adalah penyimpanan cloud dengan cadangan, sinkronisasi, dan berbagi aman bawaan. Inilah perbedaannya pada fitur ini:

Di paket gratis upload.am Layanan biasa
Name, email and date printed into downloaded files Termasuk Tidak tersedia
Stamp images, PDFs and video Termasuk Tidak tersedia
Watermark on view-only previews Termasuk Terbatas
Team-wide policy Termasuk Tidak tersedia
Lebih dari sekadar tautan berbagi file

What gets stamped

  • Images, PDFs and video downloaded through a link.
  • Other file types download unchanged.
  • PDF stamping needs the qpdf tool on the server, video needs ffmpeg.
  • On view-only links, the preview watermark is shown on the page, not stamped into the file.

Which plans include it

The preview watermark is part of view-only links. The in-file stamp is a team policy and a data room option. See plans and pricing.
