Email Tracking Pixel Finder
Paste an email's HTML to find the hidden images that report when you open it and the links that log your clicks. See where tracked links really lead, and get a clean copy with the trackers removed.
How email tracking works
Tracking pixels: a tiny, usually invisible 1×1 image. When your email app loads it, the sender's server learns that you opened the email, when, and roughly where.
Tracked links: instead of linking straight to a page, the link goes through the sender's server first, which records your click and then forwards you.
How this tool decides: an image is flagged if it's 1–2 pixels in size, hidden with CSS, or loaded from a known open-tracking address pattern. A link is flagged if it passes through a known click-tracking pattern or carries the real destination inside it. It does not flag images just because a word like "log" appears in the address, so normal images aren't removed.
How to use the Tracking Pixel Finder
- Open the email and view its source (Gmail: ⋮ then Show original; Outlook on the web: ⋯ then View message source).
- Copy the HTML part and paste it here.
- Press Find trackers to see every tracking pixel and tracked link.
- Download the cleaned copy if you want a version without trackers.
What senders learn from tracking
A tracking pixel tells the sender when you opened their email, how many times, and usually your approximate location and device. Tracked links record which links you clicked and when.
Most newsletters and marketing emails use both. Personal emails sent with tools like sales outreach software often include them too, which is how senders know you "read" their message.
For senders: using tracking responsibly
Apple Mail's privacy protection now loads pixels automatically, so open rates are less reliable than they used to be; clicks and replies are better measures of interest.
Mention tracking in your privacy policy, as data protection laws in many countries require.

Frequently asked questions
How do I get an email's HTML?
In Gmail, open the email, click the three dots and choose "Show original", then copy the HTML part. In Outlook on the web, open the message, click the three dots and choose "View message source".
Is it safe to paste an email here?
Yes. The email is read inside your browser as an inert document: its images don't load and its scripts don't run, and nothing is uploaded or stored.
Why weren't some trackers found?
Some senders use custom tracking addresses that look like ordinary images or links. The tool flags only clear signs (tiny or known tracking images and known click-tracking links) to avoid removing real content.
How do I stop tracking pixels in my own inbox?
Turn off automatic image loading in your email app, or use Apple Mail's Mail Privacy Protection, which loads images privately.
Can I tell if someone tracked an email they sent me?
Yes. Paste the email's source here. If a tracking pixel or tracked links appear, the sender is recording opens or clicks.
Does blocking images stop tracking?
It stops pixel tracking, because the pixel never loads. Clicking a tracked link is still recorded.
