Web scraping will never be the same: Introducing PixelRAG
PixelRAG is an open-source retriever framework that uses page images instead of traditional HTML parsing.
PixelRAG has been released as an open-source retriever framework that utilizes page images instead of traditional HTML parsing.
According to the developers, traditional HTML-to-text pipelines can lose over 40% of a page's content, including tables, graphs, and markup elements. PixelRAG operates on the document as it appears to the user after rendering.
How the pipeline works:
- Renders each document (web pages, PDFs, images) into a set of tiles.
- Creates embeddings using Qwen3-VL-Embedding.
- Builds a FAISS index and provides an API for searching.
The project is published in open access under the Apache-2.0 license, and the paper includes detailed error analyses and comparisons with over 25 VLM models.
