Why Your Medium Images Are Getting Stolen
Medium makes it incredibly easy for readers to engage with your work, but that same openness works against you when it comes to image protection. Anyone can right-click and save any image on your article. Anyone can take a screenshot. And because Medium articles often rank well in Google search, your images get exposed to a huge audience, including people who scrape content for their own blogs, social media accounts, or even print materials.
The reality is that a lot of image theft isn't malicious. A small blogger finds your chart, thinks it's useful, and reposts it without crediting you. A social media manager grabs your header photo for a client's post. A content farm copies your entire article, images included, and republishes it under a different byline. None of these people are necessarily trying to harm you, but the end result is the same: your work is out there with someone else's name on it, and you have no easy way to prove it was yours first.
A watermark fixes this. Even a subtle one in the corner of your image acts as a permanent signature. If someone screenshots your chart and posts it on Twitter, your name or site URL goes with it. If a content farm scrapes your article, the images still point back to you. You can't stop people from copying your images, but you can make sure every copy still leads back to you.
Which Medium Images Actually Need a Watermark
Not every image in your Medium article needs the same level of protection. Here's a quick breakdown of what's worth watermarking and what you can probably skip.
Header images
Yes, always. Your header image is the first thing readers see, and it's the image most likely to get shared on social media or picked up by other publishers. Put your watermark on it.
Original photography
Yes. If you took the photo yourself, it's your intellectual property. A watermark keeps it tied to you even if someone downloads it.
Custom illustrations and graphics
Yes. Anything you designed or commissioned deserves protection. These are often the most time-consuming to create and the most tempting for others to reuse.
Data visualizations and charts
Absolutely yes. If you built a chart from your own research or data analysis, that's original work that other writers will absolutely borrow, especially if your article ranks well.

Screenshots
Usually no. If you're just screenshotting an app interface or a website to illustrate a point, the screenshot itself isn't really your intellectual property. Watermarking it would look odd.
Stock photos
No. If you licensed a stock photo, you don't own it, and watermarking it could actually violate your license agreement. Just make sure you're following the usage terms.
The short version: watermark the images that represent your original work, and skip the ones that don't.
How Medium's Republishing and Distribution Affects Your Images
Medium has a few features that complicate image ownership in ways you might not expect. The first is the republishing feature. Medium allows other publications to republish your article (with your permission), and when they do, your images go along with it. That's generally fine if you trust the publication, but it means your images end up hosted on Medium's CDN under a different URL, and they can spread further than you intended.
The second is Medium's distribution system. When your article gets distributed to a wider audience through Medium's recommendations, your images get served to a lot more eyeballs, including people who aren't logged in and don't have any connection to you. Some of those people will save your images. A few will reuse them.
The third issue is RSS feeds and cross-posting. If you syndicate your Medium content to other platforms, or if someone scrapes your RSS feed, your images get pulled along with the text. The images live on Medium's servers, so they'll keep loading, but the context, your name, your article, can get stripped away entirely.
None of this means you should stop using Medium. The platform is great for reach. But it does mean you should assume that any image you publish there could end up somewhere else, and you should watermark accordingly. For writers juggling content across multiple platforms, our watermark guide for bloggers and content creators covers how to handle this across different sites.
Choosing a Watermark Style That Fits Medium's Clean Layout
Medium is known for its clean, distraction-free reading experience. Readers expect articles to look polished and minimal, which means a heavy or ugly watermark can actually hurt your article's performance. People might bounce if your header image looks like it's been stamped with a giant logo.
The trick is to choose a watermark style that's visible enough to do its job but subtle enough not to ruin the reading experience. Here are the main options:
Text watermarks
Your name, your site URL, or your brand name in a clean font. This is the most common choice for Medium writers because it's simple, recognizable, and doubles as a branding tool. If you go this route, keep the text short. A long URL looks cluttered. "watermarkpics.com" or "@yourname" works better than "https://www.watermarkpics.com/articles/2026/my-article".
Logo watermarks
If you have a personal brand or a logo for your publication, you can use that. Logo watermarks look professional but can be harder to read at small sizes, so make sure yours scales down well.
Translucent watermarks
A semi-transparent version of your text or logo, usually placed in a corner. This is the sweet spot for Medium images. It's visible but not obnoxious, and it doesn't compete with the content of the image itself.
The key is consistency. Pick one style and use it on every image you publish. Over time, readers will start to recognize your watermarks, which builds brand recognition on top of protecting your work. If you want help setting up a text-based version, our guide to adding text watermarks to images walks through the process step by step.
Smart Placement Strategies for Medium Images
Where you put your watermark matters more than you might think. Put it in the wrong spot and someone can crop it out in five seconds. Put it in the right spot and it stays with the image no matter what happens to it.
The corner trap
A lot of people default to the bottom-right corner because it's unobtrusive. The problem is that's also the easiest spot to crop out. If your watermark sits in a corner with empty space around it, someone can just trim that corner off and reuse the image clean. Avoid corners that have plain background around them.
The content overlay
A better approach is to place your watermark over a part of the image that has actual content, not empty space. If you have a chart, put the watermark over the chart's legend or axis area (but make sure it doesn't obscure key data). If you have a photo, place it over a textured or busy area where cropping it out would visibly damage the image.
The tile pattern
For images you're really worried about, you can repeat a faint watermark across the entire image in a tile pattern. This makes it nearly impossible to remove without ruining the image. The downside is it can look busy, so use this sparingly and keep the opacity very low.
Size considerations
Medium displays images at various widths depending on the reader's screen. Your watermark needs to be legible at full width on a desktop but also visible when the image is scaled down on mobile. Test your watermarked images at different sizes before publishing.
Step-by-Step: Watermarking Images Before You Publish
Here's the actual process for watermarking your Medium images, from start to finish.
Step 1: Prepare your images
Before you watermark anything, make sure your images are properly sized for Medium. Medium recommends images that are at least 1000 pixels wide for full-width display. Resize and optimize your images first, then watermark them. If you watermark first and resize later, your watermark might get distorted.
Step 2: Choose your watermark
Decide on your text, logo, or both. Keep it consistent with what you've used on previous articles. If you're just starting out, pick something simple that you'll be happy with long-term.
Step 3: Apply the watermark
Use an online tool (like the one on watermarkpics.com) to add your watermark to each image. Adjust the opacity so it's visible but not distracting. Position it using the strategies from the previous section. Preview the result at full size before saving.
Step 4: Check it at different sizes
Open your watermarked image and zoom out to about 50% to simulate how it'll look on mobile. If the watermark disappears or becomes unreadable, bump up the size or opacity and try again.
Step 5: Upload to Medium
Once you're happy with how the watermark looks, upload the image to your Medium article as usual. Medium doesn't strip watermarks or alter your images beyond basic resizing, so what you upload is what readers will see.
Step 6: Do a final check
After publishing (or in preview mode), open your article on both desktop and mobile. Make sure the watermarks look right in the actual reading environment, not just in your image editor.
Batch Watermarking for Writers With Multiple Articles
If you've been writing on Medium for a while, you probably have dozens of articles, each with multiple images. Watermarking them one at a time would take forever. The good news is you don't have to.
Batch watermarking lets you apply the same watermark to a whole folder of images at once. You upload multiple images, set your watermark once, and the tool applies it to every image with the same settings. This is a massive time-saver if you're going back through your older articles and adding watermarks retroactively.
Here's how to approach batch watermarking for a back catalog:
First, figure out which images actually need watermarks (refer back to the section on image types). Don't waste time watermarking screenshots or stock photos. Pull all your original images into one folder.
Second, group images by size and aspect ratio if possible. Watermark placement can look different on a wide header image versus a square inline graphic. If you can batch images with similar dimensions together, your watermarks will look more consistent.
Third, set your watermark settings once and apply them across the batch. Most tools let you preview a few samples before processing the whole batch. Use that preview to make sure the watermark looks good on different image types.
Fourth, spot-check the results. Batch processing is fast but not always perfect. Quickly scan through the watermarked images to make sure none of them ended up with a watermark that obscures important content or looks off.
If you're publishing new articles regularly, build watermarking into your workflow before you ever upload to Medium. Treat it as a standard part of your publishing process, like proofreading or formatting. Once it's a habit, it takes almost no extra time, and your images are protected from day one.
Common Watermarking Mistakes to Avoid
Even with a good tool, it's easy to make mistakes that undermine your watermark's effectiveness. Here are the ones I see most often:
Making it too small
A watermark you can barely see doesn't protect anything. If someone has to squint to read it, it's not doing its job. Make it large enough to read at a glance, even when the image is scaled down.
Making it too opaque
On the other end, a watermark that's fully opaque and covers half the image looks terrible and will hurt your article's readability. Find the middle ground. Around 30-50% opacity usually works for text watermarks on Medium.
Using an unreadable font
Fancy script fonts might look elegant, but they're hard to read at small sizes. Stick with clean sans-serif fonts for your watermark text. Legibility beats style here.
Forgetting about mobile
Most Medium readers are on mobile devices. If your watermark looks great on your 27-inch monitor but vanishes on a phone screen, it's not going to help you. Always test on mobile.
Watermarking after uploading
Some writers try to add watermarks using Medium's built-in image editor. That doesn't work. Medium doesn't have a watermarking feature. You need to watermark your images before you upload them, using a dedicated tool.
Inconsistent placement
If your watermark is in a different spot on every image, it looks sloppy and is easier to remove. Pick a consistent position and stick with it across all your articles.
Conclusion
Watermarking your Medium images isn't about being paranoid. It's about making sure the work you put into your articles, the photography, the illustrations, the charts, stays connected to you no matter where it ends up. Medium is a fantastic platform for reaching readers, but it doesn't protect your images for you. That part is on you.
The good news is that once you've got a watermarking workflow in place, it's quick and painless. Pick a style, find a placement strategy that works, build it into your publishing process, and you're set. Your images will look professional, they'll be harder to steal without credit, and every time someone encounters your work out in the wild, they'll know exactly who created it.
