If you have ever finished drawing a comic and thought “I wish I could share this with the world,” this guide is for you. WEBTOON Canvas is the largest free self-publishing platform for comics online, and learning how to publish a webtoon on WEBTOON Canvas is easier than most creators expect. I have walked dozens of new series through the process, and the steps below are the same workflow that works every single time.
By the end of this guide, you will know exactly how to set up your account, format your thumbnails correctly, upload your first episode, and start growing an audience. Publishing is completely free, you keep ownership of your work, and the platform already has millions of readers scrolling through new series every day.

What Is WEBTOON Canvas and Why Publish There
WEBTOON Canvas is WEBTOON’s free self-publishing platform where any creator can upload original comics and reach a global audience. It sits alongside WEBTOON Originals, which is the curated side of the platform featuring professionally edited series. Canvas is the open door, and Originals is the invitation-only stage.
There are three reasons I recommend Canvas to new creators. First, it costs nothing to publish. There is no submission fee, no hosting charge, and no commission taken from your work outside the optional ad revenue program. Second, you retain full ownership of your comic. WEBTOON does not buy your rights, and you can take your series elsewhere at any time. Third, the built-in audience is massive. The platform reports tens of millions of monthly readers, which means your first episode has a real chance of being discovered by someone who loves your genre.
Canvas is also the on-ramp to Originals. Editors scout Canvas regularly, and several now-famous series started as self-published Canvas titles before being promoted. So even if your goal is a paid editorial deal, Canvas is the right place to start.
Requirements Before You Start Publishing
Before you click the Publish button, make sure you meet these baseline requirements. WEBTOON requires all creators to be at least 13 years old, and creators under 18 need a parent or guardian to review the Terms of Use. You will need a valid email address, a Creator Nickname (your public display name), and access to the desktop version of the WEBTOON website through a Chromium-based browser like Chrome, Edge, or Brave.
File-wise, your episodes should be vertical scrolling images saved as JPG or PNG. WEBTOON does not accept PDFs, GIFs, or animation files for regular episodes. Your images should be at least 800 pixels wide, and the maximum file size per image is typically capped around 2 MB to keep the scroll experience smooth on phones.
You also need to read the Community Policy before uploading. The policy covers content ratings, prohibited material, and how WEBTOON handles reports. Violations can result in episodes being hidden or series being removed, so it is worth a 10-minute read before you invest time in a first upload.
How to Publish a Webtoon on WEBTOON Canvas: Step-by-Step
Below is the exact workflow I use whenever I onboard a new series. Follow these seven steps in order, and you will have your first episode live by the end of the afternoon.
Step 1: Create a WEBTOON Account and Pick a Creator Nickname
Go to webtoons.com on a desktop browser and click the Sign Up button in the top right corner. You can register with email, Google, Apple, or Facebook. After confirming your email, navigate to your profile settings and set your Creator Nickname. This is the name readers will see on every episode you publish, so choose something memorable and genre-appropriate.
Step 2: Open the Publish Page
Once you are logged in, look for the orange Publish button in the top navigation bar. Clicking it takes you to the Creator Dashboard, which is your home base for every series you manage. If you do not see the Publish button, you are probably on the mobile app or a non-Chromium browser. Switch to Chrome on desktop and the button will appear.
Step 3: Click Create Series and Fill In Your Series Information
From the dashboard, click Create Series. You will be asked for a series title, a short synopsis (around 200 characters works best), and up to two genres. Choose genres that genuinely match your story. Mislabeling helps nobody and the algorithm notices when readers bounce off your page.
Step 4: Upload Your Series Thumbnails
WEBTOON asks for two thumbnails: a square cover image (1080 x 1080 pixels) and a vertical banner (1080 x 1920 pixels). Both must be under 700 KB. I will cover the exact spec rules in the next section, but for now just know that these two images are the first thing readers see when your series appears in a genre feed.
Step 5: Set Your Content Rating and Genre Tags
Pick the rating that honestly reflects your content. The options are All Ages, Teen, and Mature. WEBTOON uses this rating to filter who can find your series, so an All Ages tag on a violent story will hurt discoverability, and an Mature tag on a cozy romance will dramatically shrink your audience.
Step 6: Upload Your First Episode
From your new series page, click Add Episode. You can drag and drop your vertical scroll images in order, add an episode title, and write a short author note for readers. Hit Save Draft if you want to come back, or hit Publish if everything looks right. Once published, your episode is live on Canvas within minutes.
Step 7: Share Your Series URL
Every Canvas series gets a permanent webtoons.com URL. Copy that link and share it on social media, in artist communities, and in relevant Discord servers. The first 24 to 48 hours after publishing matter most for the algorithm, so treat each new episode like a small launch event.
Thumbnail Specifications You Need to Follow
Your thumbnails are your series’ storefront. Most readers decide whether to click in under two seconds, and the wrong image dimensions will get your episode auto-resized into a blurry mess. Stick to the spec chart below and you will avoid the most common rejection reasons.
| Thumbnail Type | Dimensions | File Size Limit | Format |
|---|---|---|---|
| Square Cover Image | 1080 x 1080 px | Under 700 KB | JPG or PNG |
| Vertical Banner | 1080 x 1920 px | Under 700 KB | JPG or PNG |
| Episode Cover (optional) | 800 x 400 px | Under 500 KB | JPG or PNG |
Keep typography large and readable on a phone screen. Test your thumbnails by viewing them at actual size on your phone before uploading. If you cannot read the title at thumbnail scale, simplify it.
How to Publish on WEBTOON Canvas From Mobile
This is the single most common question new creators ask, and the honest answer is that the WEBTOON mobile app does not support publishing. The Publish button only appears on the desktop website, and WEBTOON has not added a mobile uploader in 2026.
That said, there is a fully working workaround. Open Chrome (or Safari) on your phone, request the desktop version of the website from the browser menu, and navigate to webtoons.com. The desktop interface will load, and the Publish button will appear. The catch is that uploading multi-image episodes through a phone browser can be slow and prone to timeouts.
For that reason, my honest recommendation is to do your actual publishing from a laptop or desktop computer. Save your mobile browser for checking notifications, replying to comments, and tracking analytics on the go.
Canvas vs Originals: Which Path Is Right for You
Canvas and Originals are two different programs under the same WEBTOON roof. Knowing the difference helps you set realistic expectations for your publishing journey.
| Feature | WEBTOON Canvas | WEBTOON Originals |
|---|---|---|
| Who can publish | Anyone 13 or older | Invite only, through editor scouting or submissions |
| Cost | Free | Free to creator, paid by WEBTOON |
| Editing support | Self-managed | Professional editor assigned |
| Ad Revenue Sharing | Eligible after threshold | Standard ad share with WEBTOON |
| Promotion | Algorithm and creator effort | Platform features and homepage slots |
| Ownership | You keep full rights | Varies by contract |
If you are just starting out, Canvas is the obvious choice. You get to publish immediately, learn what resonates with readers, and build a track record that editors pay attention to. Originals becomes relevant once you have an established audience and want professional support.
Monetization and the Ad Revenue Sharing Program
Yes, you can make money on WEBTOON Canvas. The Ad Revenue Sharing Program pays creators a share of the advertising revenue generated by their episodes. To qualify, you need to publish a minimum number of episodes and reach a threshold of weekly active readers. The exact threshold shifts over time, so check the current Creator Dashboard for the latest numbers.
Payouts are processed through the payment method you set in your account settings, and earnings accumulate from impressions and clicks on ads served against your episode pages. The share is competitive compared to other free publishing platforms, and several Canvas creators report meaningful side income once their series hit a few thousand weekly reads.
Beyond ad revenue, many Canvas creators earn through Patreon, Ko-fi, or commissions linked from their author profile. WEBTOON allows you to promote off-platform monetization as long as it does not violate the Community Policy.
First Episode Best Practices and Growth Tips
Your first three episodes are the most important chapters you will ever publish. Reviewers on r/WebtoonCanvas consistently report that most readers decide whether to subscribe within episode one. Treat those opening chapters like a pilot episode of a TV show. They need a hook, a clear premise, and an ending that demands a click on episode two.
Pace Your Story for the Scroll Format
WEBTOON readers scroll vertically, which means your panel flow should guide the eye downward rather than left to right. Avoid giant walls of text in a single panel. Break dialogue across multiple panels so the natural scrolling rhythm builds tension.
Pick a Consistent Upload Schedule
Weekly or bi-weekly is the sweet spot. Daily updates sound ambitious but quickly lead to burnout and quality drops. Pick a day you can hit reliably, and tell your readers what to expect in your series description.
Reply to Every Comment
Early engagement matters. The first 50 comments on a Canvas series often come from a small core of supporters, and replying to each one builds the kind of community that pulls new readers in through recommendations.
Collaborate With Other Canvas Creators
Shoutouts, guest panels, and cross-promotion threads in the Canvas community are still one of the best growth levers. Find three to five creators in adjacent genres and build a quiet alliance where you all boost each other’s new episodes.
Polish Before You Publish
Resist the urge to upload a rough draft just to get something live. Spend an extra week polishing the lineart, lettering, and pacing of your first three episodes. The creators I have seen break out almost always had strong early chapters to point new readers toward.
Troubleshooting Common Upload Issues
If your upload is failing, run through this checklist before contacting support. Most issues come down to one of these five causes.
Browser problems: Switch to the latest version of Google Chrome. Firefox, Safari, and Edge sometimes choke on the drag-and-drop uploader.
File size too large: Compress your images to under 2 MB each using a tool like Squoosh or Photoshop’s Save for Web. WEBTOON will reject oversized files without a clear error message.
Wrong file format: Only JPG and PNG are accepted. Convert HEIC, WebP, or PSD files before uploading.
Lost work from a closed tab: Always use the Save Draft button before closing the browser. WEBTOON does not auto-save unpublished episodes.
Drafts not appearing: Drafts live in the Creator Dashboard under the Drafts tab. If you cannot find a missing draft, clear your browser cache and log in again.
