Compress webcomic pages so your episode upload clears every platform cap

Every webcomic platform runs its own upload wall. WEBTOON CANVAS wants each panel image 800px wide and no taller than 1280px at roughly 2MB, with about 20MB per episode. Tapas takes pages 940px wide with no height limit but caps each file at 10MB and restricts GIFs to 1000px tall. GlobalComix accepts almost anything and optimizes for you. A single 40MB layered export or a 6000px-tall strip fails the upload with no useful error, and one bad file blocks the whole episode. Skwish compresses and resizes images locally in your browser with a live before/after size readout per panel, so you bring a whole episode under the cap while keeping line art and text sharp. Batch the panels, export a ZIP. Nothing is uploaded to a server.

Webcomic upload notes

Use these before you upload or share the page.

Compress for the platform cap, not for the screen. WEBTOON Canvas takes 800px-wide panels, so resize first and then cut weight from the encoding — text and line art are what degrade first.

Check the per-episode budget, not just the per-file budget. WEBTOON Canvas is roughly 2MB per image and about 20MB per episode, so a 30-panel chapter needs every file lean.

Keep the archive in JPG for photographic backgrounds and PNG for flat colour with hard edges. Mixing formats per panel type keeps quality where it shows.
