Copyright Check Online: Free vs Paid Tools Compared (2026)
Comparing the best online copyright check tools in 2026. From Google Lens to specialized scanners, here's what each one can and can't tell you about image copyright.
By Suraj, founder of PixGuard · Published · Updated
So you need to figure out if an image is copyrighted. Maybe you're auditing your website. Maybe you just got a sketchy looking demand letter. Either way, you need a tool.
We compared the most popular options so you don't have to guess. Here's how they actually stack up.
The Tools Compared
| Tool | Type | Price | What It Does |
|---|---|---|---|
| Google Lens | Free | $0 | Reverse image search |
| TinEye | Freemium | Free for non-commercial use; paid API from $200 for 5,000 searches | Reverse image search |
| Copyscape | Freemium | Limited free search; Premium from $0.03/search | Text plagiarism checking |
| Adobe Content Credentials | Free | $0 | C2PA metadata only |
| PixGuard | Freemium | $0 to $79/mo, plus credit packs | Website image copyright risk scanning |
Google Lens (Free)
Google Lens finds visually similar images across the web. You paste or upload an image and it shows you where similar ones appear.
What's good:
- Totally free
- Massive image index
- Dead simple to use
What's not:
- Mixes exact copies with merely similar images, so a result isn't always your image
- Can't tell you who actually owns the copyright
- No watermark detection at all
- No metadata analysis
- One image at a time (no batch processing)
Best for: A quick sanity check on a single image to see if it shows up on stock sites.
Our take: Useful as a starting point, but if Google Lens finds nothing, that doesn't mean you're free to use the image. It just means Google didn't find an obvious match.
TinEye
TinEye is a reverse image search engine built specifically for tracking images across the web. It's been around for years and has a solid reputation.
What's good:
- Built to find altered copies (cropped, resized, color-adjusted) of the same image
- Shows you where an image appears across the pages it has indexed
- Has an API if you want to integrate it
- Can track how an image spreads over time
What's not:
- Finds copies of the same image, not similar images
- No watermark detection
- No metadata analysis
- API use is paid (from $200 for 5,000 searches)
- Still only handles one image at a time
Best for: Photographers and agencies who want to track where their own images end up.
Our take: Solid for reverse lookups, but it can't tell you whether you have the right to use an image on your website.
Copyscape
Copyscape is the go-to for text plagiarism checking. It checks text, not images.
What's good:
- Industry standard for text content
- Cheap per search pricing
What's not:
- No image copyright checks
- Built for text
- No watermark or metadata detection
- Can't scan a website's images
Best for: Checking if someone copied your blog post. Not for images.
Our take: Wrong tool entirely if your problem is image copyright.
Adobe Content Credentials
Adobe is pushing a new standard called C2PA (Coalition for Content Provenance and Authenticity) that tracks where an image came from and how it's been edited. Their Content Credentials tool reads this data.
What's good:
- Free to use
- Transparent origin tracking when it works
- Shows the full edit history
What's not:
- Only works on images that have C2PA metadata (which is almost none right now)
- Doesn't help with existing stock photos at all
- Doesn't look for stock-agency watermarks
- Most images on the internet simply don't have content credentials yet
Best for: Checking provenance on AI generated images that opted into the C2PA standard.
Our take: Cool technology that might matter in a few years. Right now, it's not practical for real copyright checking.
PixGuard
Full disclosure: this is our tool. But we built it specifically because the options above weren't cutting it for people who actually run websites.
PixGuard checks the images on a website for copyright risk signals and gives each one a 0 to 100 risk score with the reasons behind it.
What's good:
- A free page check, no signup. Enter a page URL and we check the 3 largest images on that page, up to 3 times a day. Uploads and 30 image scans need a free account.
- Website scanning with an account. A website scan follows links across up to 50 pages and scores the images it finds, up to your plan's per-scan limit (10 new images per scan on Free, 500 on Pro, 2,000 on Business).
- Several checks per image in account scans:
- EXIF, IPTC and XMP copyright fields
- Visible watermark text and logos from 7 stock agencies, plus tiled watermark patterns
- Matches against a database of reference image fingerprints
- Error level analysis for signs of editing
- An AI-generation estimate
- On Pro and Business: similarity matching for edited or cropped copies, AI vision review of borderline images, and source lookup (web pages where a matching image appears) for high-risk images
- Smart caching so images PixGuard has already analyzed are shown from cache at no cost
- Clear risk scoring from Safe to Critical, with the signals behind each score
- A free account includes 30 image scans, valid for 30 days, no credit card required
What's not:
- Credit based pricing: every plan has an image allowance
- Doesn't decode invisible watermarks
- The crawler reads the HTML your server sends and doesn't run JavaScript, so images loaded by scripts can be missed
- A risk score tells you what to investigate. It isn't a legal finding
- Focused on websites (no mobile app yet)
- We're newer, so the community is still growing
Best for: Website owners, online stores, bloggers, and marketing teams who want to know which images on their site need a closer look.
Our take: If you need to review the images across a website (not just check one image), this is what we built it for.

So Which One Should You Actually Use?
Just checking one image real quick? Google Lens is free and fast. If it shows up on a stock site, you know where to look for a license.
Photographer tracking your own work? TinEye was literally built for that use case.
Running a website with lots of images? That's what PixGuard is built for. Try the free page check (the 3 largest images on the page, no signup), then use a free account to scan across up to 50 pages and get a risk score, with the signals behind it, for each image it checks.
Here's the reality: reverse image search only tells you where similar images appear. It doesn't read copyright metadata or look for stock watermarks, and none of these tools can tell you whether you hold a license. Use them to decide which images to investigate, then check your records.
Try it yourself. Create a free PixGuard account for 30 image scans, valid for 30 days. No credit card required.
See which images on your site need a closer look
Paste a page URL and PixGuard checks its 3 largest images for copyright risk signals, free and without signup. A free account adds 30 image scans (valid 30 days); each site scan crawls up to 50 pages and checks up to 10 new images on the free plan.
