ZIP, email and download links

Open a DICOM ZIP from email, WhatsApp or a download link

If your scan came as a ZIP, you don't need to unzip it. Save the file, click Open files or a ZIP… and MesDICOM reads the images straight from the archive — on a computer or a phone, free, nothing uploaded.

  • No account, no upload, nothing to install
  • Reads a whole folder, disc or USB drive
  • Window presets, measurements, three planes and 3D

A disc, a folder, a ZIP or DICOM files — or choose what you have:

Paste works too: Ctrl+V

In an email or WhatsApp?

Save the attachment first, then open it here. A ZIP doesn't need unzipping.

On a CD or DVD? Phones can't read discs. Open mesdicom.com on a computer with a disc drive.

On a CD or DVD?

Three steps, no program to install.

  1. Insert the disc. If a viewer program starts, close it.
  2. Click Open a disc or folder… and select the disc drive itself.
  3. Don't pick DICOMDIR or the viewer program. MesDICOM finds the images on the disc.

Save the ZIP to your computer or phone, click Open files or a ZIP… above and choose it. MesDICOM unpacks it in your browser, keeps the DICOM images and opens your study. Nothing is uploaded.

How do I open a ZIP from an email or WhatsApp?

  1. Save the attachment. In your email or WhatsApp, download or save the file first — a browser can only open a file that is on your device.
  2. Open it here. Click Open files or a ZIP… and choose the file, or drag it onto this page.
  3. Choose a study if the ZIP holds more than one. MesDICOM sorts the images into studies and series.

Download the file from the link first. If the hospital's portal asks you to sign in, sign in there. Some portals offer a choice of formats: pick the DICOM images, usually as a ZIP. A portal's own online viewer is separate from the download and isn't needed.

Which archives open?

A ZIPOpens, without unzipping
A self-extracting ZIP or a very large ZIP (ZIP64)Opens
A password-protected ZIPUnpack it with the password in another app, then choose the folder
A ZIP split into several partsJoin the parts or unpack them in another app, then choose the result
RAR, 7-Zip or ISONot yet: unpack it and choose the folder, or ask for a ZIP

If a ZIP holds only a viewer program or a report and no images, MesDICOM says so.

How big can the ZIP be?

Large is fine. MesDICOM reads the archive entry by entry instead of loading all of it into memory. In our tests a whole-disc ZIP of 680 MB opened completely in about half a minute, and the first image showed long before that.

Is it private?

Yes. The ZIP is unpacked by your browser on your device. Your images, the patient's name and the file names aren't sent to us or to anyone else. What is unpacked for viewing is cleared when you open something else, unless you choose Save to Library.

MesDICOM is for viewing and reference only — not intended for diagnosis or treatment decisions.

Questions

Do I have to unzip the file first?

No. MesDICOM reads the images straight from the ZIP. Unzipping also works — then choose the folder it makes.

The ZIP asks for a password. Can MesDICOM open it?

Not in the browser. Unpack it with the password in another app, then choose the folder it makes with Open a disc or folder….

The hospital sent a RAR, 7-Zip or ISO file. What now?

These can't be opened in the browser yet. Unpack it on your computer and choose the folder it makes, or ask for the study as a ZIP. The MesDICOM apps for iPhone, iPad and Mac open RAR, 7-Zip and ISO directly.

Can I open the ZIP on my phone?

Yes. Save the attachment to your phone first, then open mesdicom.com and tap Open files or a ZIP….
