Web Novel Cover Resizer Guide & FAQ
💡 Pro Tips for Best Results
1. High-Quality Original: Always prepare the highest resolution original image (PNG/JPG) received from your illustrator. Forcibly enlarging a small image will severely degrade quality and reduce reader clicks.
2. Select Platform: Choose your target serialization platform (KakaoPage, Naver Series, Munpia, etc.). Each platform requires different ratios and pixel dimensions, but Pyozi AI always reflects the latest specs so you don't have to search manually.
3. Check Typography & Alignment: Carefully check the preview screen to ensure important elements like typography (title) or the character's facial features aren't cropped out during the resizing process.
4. Auto-categorized Download: Clicking the 'Download' button instantly saves the file with a name containing the platform and specific dimensions, preventing file mix-ups when publishing across multiple platforms simultaneously.
Q. Are my unreleased cover images saved on your servers?
A. Absolutely not! You don't need to worry about leaks. The Resizer tool operates 100% inside your browser (local client). Not a single byte of image data is sent to our servers, making it the most secure resizing method.
Q. Won't resizing the image make the text blurry or degrade quality?
A. We use top-tier resampling algorithms supported by the browser to convert sizes. This guarantees high-quality results optimized for mobile web novel thumbnails, maintaining crispness.
Q. Can I resize covers on a mobile device?
A. Yes, you can simply select a web novel cover image from your mobile gallery or take a picture, upload it, and easily convert and download it.
