How to Open and Read a PDF with EditPDF AI
Written and fact-checked by The EditPDF AI Team
EditPDF AI’s PDF Viewer opens supported PDF files locally in your browser. You can navigate pages, zoom, and use fullscreen without creating an account or installing a desktop application.
Step-by-step: view a PDF online
- 1Open editpdfai.com/pdf-viewer and drag a PDF onto the page, or use the file picker.
- 2The file loads locally in your browser — no application document-processing request is made.
- 3Move between pages, zoom from 10% to 800%, or enter fullscreen where your browser supports it.
- 4On touch devices, swipe between pages at fit width. Download the unchanged file, or close it to open another.
What the viewer does — and doesn't — support
- ·No text search — the current viewer renders pages on canvas without a search control or searchable text layer
- ·No password entry — a protected PDF may fail to open; unlock it first if you are authorized to
- ·No fixed size limit — practical capacity depends on file size, page count, browser memory, and device performance
Need more than viewing?
Use PDF Editor to make changes, PDF Annotate to add comments and highlights, or PDF OCR first if you need to search a scanned document's text.
Choose a different workflow when reading is not enough
Use PDF Annotate for review notes or PDF Editor for supported document changes. If you need to search text, open the file in a search-capable reader; image-only scans need a usable OCR layer first. If the file will not load, follow the PDF opening troubleshooting guide.
