Streamlit component for PDF visualisation and manipulation
Decision gist · record as of 2026-08-14
Yes, if you need to display PDFs in a Streamlit app and can tolerate active-development limitations. Install friction is low and the component is actively maintained. However, verify the license status in the repository, test with your target Streamlit version (avoid 1.41–1.58), and be aware that complex PDFs may render slowly due to Streamlit's reload behavior. Not recommended for production use cases requiring guaranteed stability or fast troubleshooting response.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Streamlit versions 1.41–1.58 have a known regression affecting custom-component iframe scroll handling; use Streamlit ≥1.59.0 or ≤1.40.2 to avoid this issue.
- Low install friction with a single runtime dependency on streamlit.
- Active maintenance with recent releases; however, the project is explicitly described as a side project where troubleshooting may take time, and the component is still in development with known bugs and limitations.

What it is and what it does
streamlit-pdf-viewer is a Streamlit custom component that embeds PDF rendering directly into web applications using the pdf.js library. It allows you to display PDF files with interactive controls—zoom, page navigation, and scrolling—and overlay annotations on top of the document. The component supports rendering text on PDFs for copy-paste functionality, custom callbacks when annotations are clicked, and configurable layout options like alignment and page separators.
The package is lightweight, requiring only streamlit as a runtime dependency, and installs with low friction. However, it is maintained as a side project and explicitly remains in active development; the documentation notes known limitations (Firefox and Chrome only, potential slowness with complex PDFs due to Streamlit's reload behavior) and cautions that troubleshooting may be slow. A specific Streamlit version range (1.41–1.58) has a regression that breaks scroll position after dialogs close; the maintainer recommends Streamlit ≥1.59.0.
Use it for
- Embed PDF documents in Streamlit dashboards or data applications without requiring users to download files.
- Build document review or annotation tools where users can mark up PDFs and trigger callbacks on interaction.
- Display multi-page reports or technical documentation with zoom and navigation controls within a Streamlit UI.
- Create document processing pipelines that visualize PDFs alongside extracted data or analysis results.
- Render text-based PDFs with copy-paste support for data extraction workflows.
