Tapas vs. WEBTOON: Key Dimension & File Size Differences
Cross-post without rebuilding the episode. Start with a clean master, then make a deliberate export for each platform’s current upload rules.
WEBTOON vs. Tapas spec comparison
WEBTOON and Tapas share a vertical-reading audience, but their upload contracts are not identical. The width is the clearest difference: WEBTOON CANVAS specifies 800 × 1280px maximum per image, while Tapas currently documents 940px-wide comic pages. Tapas states no height limit for JPG and PNG; the 4000px figure is a common legacy working slice, not a current hard limit on its public Help Center.
| Check | WEBTOON CANVAS | Tapas comics |
|---|---|---|
| Maximum width | 800 px | 940 px |
| Slice height | 1280 px maximum per image | No height limit for PNG/JPG; 1000px maximum for GIF. Many creators still export 1280px or 4000px working slices. |
| Per-file limit | 2 MB per image | Check the live uploader: Tapas’ Help Center says under 10 MB, while its creator size guide lists under 2 MB per individual file. |
| Total episode limit | 20 MB total; up to 100 images in the cited upload FAQ | Tapas’ creator size guide lists under 20 MB total per episode. |
| Supported formats | JPG/JPEG and PNG | PNG, JPG, or GIF; GIF height is capped at 1000px. |
Its Help Center currently says 940px wide, no height limit, and under 10 MB; the creator file-size guide says under 20 MB total and under 2 MB per individual file. Export conservatively, then treat the live uploader as the final authority for your account.
WEBTOON also says images beyond its maximum dimensions may be optimized in several ways, including slicing, resizing, format changes, or quality reduction. Pre-exporting within its limits means you can check the actual result before upload.
How to draw one master file for both platforms
Use a wide, high-quality master that divides cleanly to both endpoints. 1600px reduces exactly to WEBTOON’s 800px width; 1880px reduces exactly to Tapas’ 940px width. A 2000px master is also a sensible flexible working size when exact divisibility is less important than your drawing workflow.
- Keep the layered original. Build lettering and art at a width that leaves room for reduction; do not make the 800px or 940px export your only master.
- Export a WEBTOON copy. Resize proportionally to 800px and divide it at no more than 1280px high.
- Export a Tapas copy. Resize the same master proportionally to 940px, then choose a practical vertical split for review and upload order.
- Review both at phone size. Read small speech bubbles, inspect panel boundaries, and confirm the actual file sizes before publishing.
Switch between 800 × 1280 and 940 × 1280 presets in one click with the free in-browser CreaPocket Slicer — zero uploads required.
Do not resize the 800px WEBTOON copy up to 940px for Tapas. That invents pixels and can soften text. Make both final exports independently from the high-resolution source.
Vertical-scroll pacing and gutter differences
The technical width changes how empty space feels. At 940px, a gap can appear slightly more generous than the same art at 800px; after downscaling, narrow gutters and thin lettering are the first details to disappear. Build pacing around a phone preview, not only the desktop canvas.
For both platforms, use vertical whitespace intentionally: a short gap connects beats, a larger gap gives a reveal room to land, and a long pause should have a story reason. Avoid placing dialogue or a facial reveal directly on a file boundary. On WEBTOON, you must also plan around 1280px slices; Tapas offers more vertical flexibility for PNG/JPG, but smaller working slices can still make revisions and upload ordering easier.
- Check speech bubbles after the 800px export, even if they read at 940px.
- Keep a safe gutter around critical panel transitions and slice boundaries.
- Use each platform’s preview before publishing; Tapas explicitly recommends checking legibility on mobile and desktop.
- Keep filenames numbered so each platform’s upload sequence is unambiguous.
Four common cross-posting questions
Can I upload 800px WEBTOON slices directly to Tapas?
Yes, 800px is below Tapas’ documented 940px width. But Tapas readers may see a less detailed version than a native 940px export. For the best result, export a separate 940px copy from the master and compare it on a phone.
How do I batch-export for both platforms in seconds?
Keep two export presets: WEBTOON at 800px wide and 1280px-high slices; Tapas at 940px wide with your preferred vertical split. In CreaPocket, switch between the Webtoon and Tapas presets, process from the original source each time, and label the ZIPs by platform.
Is 4000px a current Tapas height limit?
Not according to Tapas’ current public comic publishing and file-size pages, which say no height limit for PNG/JPG. 4000px remains a useful working-slice convention from older guidance, but it is not presented there as a current hard limit. Verify in the live uploader before a large release.
Should I make two versions of every panel?
Usually no. One layered master can serve both platforms. Make two final exports with different widths, then adjust only if a detail becomes unreadable or a platform preview exposes a pacing issue.
