What it does

Everything about your camera's life.

From a photo

Drop in a JPEG or RAW

CR2, CR3, NEF, ARW, RAF, ORF, RW2, PEF and DNG. The count is read from data the camera writes into every file.

Over USB

Plug in a Canon DSLR

Canon DSLRs keep their count inside the camera. Connect one with a cable and Shutterlab asks it directly. No drivers needed.

Condition

A grade you can trust

Compares the count with the maker's rated shutter life, or a typical 100,000 when none is published, and grades it from Excellent to Past rating.

Cards

Every brand, its own card

Results come on a card in your camera brand's colours, ready to save as an image for a sale listing, with an option to hide the serial number.

Gallery

Browse your photos, RAW included

Add a folder and scroll through every shot instantly, with filters by camera and a full-screen viewer with lens and settings.

Private

Nothing leaves your PC

No account, no cloud, no tracking. Every check and photo stays on your computer, and the app works with no internet at all.

How it works

Three steps.

Take a fresh photo
Copy the original file straight off the memory card. Edited or exported copies often lose the counter.
Drop it in
Drag it onto the window or click to browse. Canon DSLR? Plug the camera in by USB instead.
Read your card
The exact count, the camera's model and serial, and how much of its shutter life is used.

Questions

FAQ

Is it really free?

Yes. Checking shutter counts is free with no limits, no trial and no account.

Why doesn't my Canon DSLR work with a photo?

Canon DSLRs keep the count inside the camera and never write it into photos. Connect the camera with a USB cable, close EOS Utility, and choose "Read a camera over USB".

It says "not in this file" for a camera that should work.

The photo was probably edited or exported. Lightroom, Photos and social media often remove the data the count lives in. Copy a fresh original straight off the memory card.

How accurate is the condition grade?

The count is exact, read from the camera's own data. The grade compares it with the maker's published shutter rating where there is one, otherwise a typical 100,000. Ratings are an average, not a limit: many shutters last far longer.

Windows says "Windows protected your PC". Is it safe?

That message appears for apps that aren't signed with a paid certificate. Click "More info", then "Run anyway".
