Seamlessify vs Tanzitex AI

Seamlessify turns images into repeating patterns, with PNG, JPG, and batch ZIP exports. The web tool accepts PNG, JPG, and WEBP files, with batches of up to 100 images or 500 MB. For direct stitching, supported images are processed in the browser rather than uploaded to the maker’s image-processing servers. The tool blends opposite edges to soften seams and abrupt color changes, and lets you set the number of rows and columns independently. A 3 × 3 preview helps inspect a repeat; output options include seamless tiles, horizontal rolls, and vertical panels. Downloads are rendered from the original image. AI generation can use a text prompt or derive a prompt from a reference image, but requires an account and credits. The listed models are Z-Image Turbo and Ideogram V4 Tiling, delivered through fal.ai; DeepSeek V4 Flash Vision Experimental analyzes reduced reference images. AI generations and related records are kept privately for up to 30 days before scheduled deletion. The free plan includes two one-time AI credits after email verification and unlimited direct stitching; paid plans start at $8.25/mo (annual).
