Compress images for WEBTOON Canvas without failing the 800px and 2MB upload spec

WEBTOON CANVAS has a narrow upload lane: panel images 800px wide, no taller than 1280px each, roughly 2MB per file, and about 20MB for the whole episode. WEBTOON's own slicing now splits long vertical strips for you, but that does not make an oversized or wrong-width file acceptable — the upload still rejects it, usually without telling you which panel was the problem. On a 25-panel episode that hunt costs an evening. Skwish compresses and resizes images locally in your browser with a live before/after readout per panel, so every file lands inside the spec while the line art and lettering stay readable on a phone screen. Batch the panels, export a ZIP, upload once. Nothing leaves your device.

WEBTOON Canvas notes

Use these before you upload or share the page.

Width is fixed at 800px in the Canvas spec, not a maximum. Resize the whole batch to 800px wide first, then compress — compressing a 2400px-wide file only wastes bytes.

Budget ~2MB per image and ~20MB per episode. If your chapter runs 30 panels, aim closer to 1MB each or the last few uploads fail.

JPG and PNG only. If your editor exported WebP or a layered format, convert while you are already in the tool rather than re-exporting from scratch.
