However, tokenizers constructed on pre-trained vision foundation models (VFMs) often struggle to balance semantic richness and reconstruction fidelity in high-dimensional latent spaces. In this paper, we introduce DINO-Tok, a visual tokenizer built upon a frozen DINO encoder that supports both continuous autoencoding (DINO-Tok-AE) and discrete vector-quantization (DINO-Tok-VQ). By unifying hierarchical representations from both shallow fine-grained features and deep global semantics into an information-complete latent space, DINO-Tok preserves texture details while maintaining \\textit{semantic consistency} for generation. We further investigate VQ in frozen semantic feature spaces of high dimensionality, where information dilution and codebook collapse frequently arise. To address this issue, we propose Dominant-Subspace Quantization (DSQ), which leverages a global PCA analysis to select principal components while suppressing noisy dimensions, thereby stabilizing codebook optimization and improving reconstruction and generation quality. On ImageNet 256x256, DINO-Tok achieves strong reconstruction performance, achieving 0.28 rFID for continuous autoencoding and 1.10 rFID for discrete VQ, as well as strong few-step generation performance 1.82 gFID for diffusion and 2.44 gFID for autoregressive generation. These results demonstrate that pre-trained VFMs such as DINO can be directly adapted into high-fidelity, semantically aligned visual tokenizers for next-generation latent generative models.
