Everything you need to know about bringing a chapter to OnePanel Reader. Still stuck? See the spoiler-free reading guide.
- What is OnePanel Reader?
- OnePanel Reader is a web app that reveals a manga chapter one panel at a time, so you never see the next panel or page before you're ready for it.
- How does OnePanel Reader prevent spoilers?
- Instead of showing a full scanned page with several panels at once, OnePanel splits the chapter into individual panels in reading order and shows only the current one. You move forward and back with the left and right arrow keys.
- Which chapter sources does OnePanel Reader support?
- You can upload one CBZ, CBR, ZIP, RAR, or PDF comic, select multiple JPG, JPEG, PNG, or WebP page images, or paste a chapter URL from opchapters.com or tcbonepiecechapters.com. Multiple images are ordered by filename.
- What happens to uploaded files?
- Uploaded files are deleted after analysis. OnePanel keeps only the panel layout data, and you will need your original files again after the current browser session ends.
- How much does OnePanel Reader cost?
- Standard mode is free, with no card or trial required. OnePanel Pro is €4.99 per month and adds GPT‑5.6 Layout for better panel detection on complex page layouts.
- Can I cancel my subscription any time?
- Yes. Billing is handled by Stripe, and you can cancel or manage your subscription any time from the billing portal in your account.
- Do I need an account to use OnePanel Reader?
- You can paste a supported chapter link and use Standard mode without an account. File uploads require sign-in. Subscribe to OnePanel Pro when you want GPT‑5.6 Layout.
