Disclaimer: Not All Free Cartoon Sites Are Equal
This list includes both fully licensed streaming services and platforms whose licensing status could not be independently verified. YouTube, Tubi, Cartoon Network, RetroCrush, Hulu, Paramount+, Fox, and Fandango at Home operate under standard licensing and advertising agreements. SuperCartoons and ToonJet host classic, largely older cartoons, but we could not confirm formal licensing arrangements for these platforms, so treat them with added caution.
We do not endorse or encourage the use of unlicensed streaming sites. If you try any platform with unclear licensing, use a reputable ad blocker and updated antivirus software, avoid downloading files, and never enter payment details on a site without clear ownership information. Laws and enforcement vary by country and change over time, so this article is for informational purposes only and does not constitute legal advice.

A Short Comparison of Cartoon Sites
Compare free access, licensing, and the best options to watch cartoons online.
1. YouTube
YouTube remains the single best source to watch cartoons online for free, and it needs no introduction. Its scale, licensing partnerships, and family‑safe features make it the safest starting point on this list.
Thousands of official channels host full episodes, clips, and classic cartoons legally, including verified channels from major studios. You do not need to register to watch, though logging in unlocks likes, comments, and personalized recommendations. YouTube also offers rent‑or‑buy options for newer content that is not available for free.
Features:
- Watch cartoons online for free in multiple resolutions, from standard definition up to 4K on supported channels.
- No signup required to view most content; an account is only needed to comment or like videos.
- Massive catalog spanning classic reruns, official studio channels, and independent animators.
- YouTube Kids offers a filtered, ad‑lighter environment for younger viewers.
2. Tubi
Tubi is a fully licensed, free, ad‑supported streaming platform with a genuinely large cartoon and anime section, including dedicated kids and family hubs. It has become a common recommendation as a safer replacement for unofficial anime and cartoon aggregator sites.
Because Tubi operates under standard licensing and advertising agreements, it avoids the domain‑hopping, aggressive pop‑up, and malware risks associated with some unofficial “free anime” sites.
Features:
- Large, licensed cartoon and anime catalog at no cost.
- Dedicated kids and preschool content sections.
- No subscription required; supported entirely by advertising.
- Available on smart TVs, streaming boxes, and mobile devices.
3. Cartoon Network
Cartoon Network’s official platform gives direct, licensed access to its entire back catalog, spanning decades of programming for viewers of all ages. The site updates its library regularly and keeps its ad load lighter than many competing free sites.
Because Cartoon Network owns the rights to its own shows, this is one of the cleanest legal ways to revisit classic series or catch new episodes without piracy‑related risk.
Features:
- A large, officially licensed catalog covering nearly every show the network has aired.
- No account required for most content, and no aggressive pop‑up advertising.
- Optimized for both desktop and mobile browsing.
- Regularly updated with new episodes shortly after broadcast.
4. RetroCrush
RetroCrush is a dedicated classic‑anime platform that runs on official licensing partnerships rather than unauthorized uploads. It focuses on older anime series that are harder to find on mainstream platforms, making it a strong pick for nostalgic anime fans who still want a fully legal option.
Its free, ad‑supported tier covers a meaningful portion of its catalog, with an optional subscription for extended access.
Features:
- Licensed classic anime catalog, including titles rarely available elsewhere.
- Free, ad‑supported streaming with an optional paid tier.
- Straightforward browsing by series and era.
- Built specifically around legal distribution agreements, unlike many anime aggregator sites.
5. Hulu
Hulu is a fully licensed streaming service that combines next‑day network episodes with a deep back catalog of animated series and films. It works across smart TVs, phones, tablets, and browsers.
Its free tier is limited, and most of its cartoon catalog sits behind a subscription, but Hulu remains one of the most reliable legal options for both kids’ programming and adult animation. It also carries current-season episodes from major networks shortly after they air.
Features:
- Access to current and past seasons of many animated series.
- Original programming and award‑winning documentaries alongside licensed cartoons.
- Content spans family‑friendly shows and adult animation for older viewers.
- Available on most streaming devices and smart TVs.
6. Paramount+ (Home of South Park)
If you’re specifically looking to watch cartoons like South Park online, Paramount+ is now the exclusive streaming home for the entire series, including all past seasons and new episodes. South Park left HBO Max in August 2025 after a licensing change, and Paramount reportedly paid roughly 1.5 billion dollars for global streaming rights through 2030, consolidating the full library in one place for the first time. If you previously watched the show on Max, our guide to HBO Max sign‑in and compatible devices explains how that platform’s device setup works, though South Park itself has since moved.
New episodes typically premiere on Comedy Central and stream on Paramount+ the next day. Paramount+ offers a free trial period and an ad‑supported tier, making it one of the more affordable paid options on this list.
Features:
- Complete South Park library, from Season 1 through current seasons.
- New episodes available the day after they air on Comedy Central.
- Ad‑supported and ad‑free subscription tiers available.
- Also hosts other adult animation and licensed cartoon content beyond South Park.
7. Fox
Fox’s official streaming hub gives legal access to its animated lineup, including long‑running adult animation staples alongside family programming and live sports. The catalog updates alongside broadcast schedules, and the interface directs users toward recently aired episodes.
Because this is Fox’s own platform, all content is fully licensed, which makes it a safer choice than unofficial mirrors carrying the same shows.
Features:
- Legally stream Fox’s animated series alongside its broader entertainment catalog.
- Official mobile apps for on‑the‑go viewing.
- No registration required for ad‑supported streaming.
- Live TV and streaming schedules available through the same platform.
8. Fandango at Home (formerly Vudu)
Fandango at Home, the rebranded version of Vudu, is a US‑based digital storefront and streaming service with a partnership tied to Cartoon Network content. It blends free, ad‑supported titles with a larger rent‑or‑buy library.
Because Fandango at Home operates as a licensed digital retailer, its cartoon catalog is legally cleared, though the free selection is smaller than subscription‑based competitors.
Features:
- Weekly‑updated free movie selection alongside paid rentals and purchases.
- Cloud‑based library that stores purchased titles in one account.
- Sorting by genre, character, and release period.
- Mix of free ad‑supported titles and premium purchases.
9. SuperCartoons
SuperCartoons focuses on golden‑age animation, with a catalog built around Disney and Looney Tunes-era characters. The interface groups shows by character, studio, and series, which makes it easy to browse without an account.
This site leans on classic, older cartoons, but we could not independently verify its licensing arrangements. As with most ad‑supported free cartoon sites of this kind, be cautious of third‑party ad networks and avoid downloading anything the site prompts you to install.
Features:
- Classic characters including Tom and Jerry, Road Runner, Popeye, Donald Duck, and Bugs Bunny.
- Browsing by series, character, or studio.
- No signup required to start watching.
- Works across desktop and mobile browsers.
10. ToonJet
ToonJet specializes in vintage cartoons, including Mickey Mouse and Tom and Jerry, alongside some newer series like Pokémon and Samurai Jack. Much of its core library draws on older works, though we could not independently verify formal licensing arrangements for the platform.
The interface is simple, and no registration is required, though the site’s older design can feel dated compared to modern streaming platforms. Treat this as an unverified option and apply the same caution as with SuperCartoons.
Features:
- Small, straightforward interface with minimal clutter.
- One of the longest‑running free cartoon sites still active.
- No registration required to browse or watch.
- Community rating and comment features on individual videos.
Bottom Line
Streaming has permanently changed how people watch cartoons online, giving viewers access to decades of programming on demand instead of waiting for a Saturday morning time slot. Eight of the ten platforms on this list, including YouTube, Tubi, Cartoon Network, RetroCrush, Hulu, Paramount+, Fox, and Fandango at Home, operate as fully licensed services and are safe default choices for most viewers. For a deeper comparison across paid and free tiers, revisit our best video streaming services guide.
SuperCartoons and ToonJet remain popular for classic cartoons, but their licensing status is unverified, so treat them with more caution than the fully licensed options above. If safety, legal clarity, and consistent quality matter most, especially for children’s viewing, prioritize YouTube, Tubi, Cartoon Network, and the other licensed platforms first
