CreaPocket offers a suite of browser-based services designed for digital comic creators, illustrators, and web developers. These tools operate entirely within your web browser, utilizing HTML5 Canvas and WebAssembly to process artwork and folders without ever sending data to external servers. The suite includes two standout features:
1. Webtoon & Manga Image Slicer: This tool automatically scales and slices long vertical comic strips into platform-ready pages in a matter of seconds. Users can choose from preset formats like WEBTOON Canvas (800 × 1280 px), Tapas Standard (940 × 1280 px), or specify a custom slice height. Oversized canvas widths are automatically downscaled before slicing to maintain image quality. The tool exports sequentially numbered slices as individual images (e.g., part_001.jpg, part_002.jpg) with just one click.
2. Batch Folder Image Compressor & Resizer: This utility allows users to drop an entire nested folder of images, which are then bulk compressed and resized while preserving the original folder structure. The tool supports format conversion between WebP, JPEG, and PNG, with adjustable quality settings and smart size guards to maintain image integrity. It also bypasses the typical 20-file / 5MB size limits imposed by many cloud-based compressors.
