You need to upload a PDF file so Perplexity Pro can read, summarize, or extract data from it. The Pro subscription includes a file upload feature that supports PDFs, images, and text files. This article explains how to upload a PDF, what analysis options are available, and common limitations to avoid.
Key Takeaways: Uploading PDFs for Analysis in Perplexity Pro
- File upload button in the query box: Click the paperclip icon next to the text input to select a PDF from your device.
- Supported file types: PDF, PNG, JPG, CSV, TXT, and DOCX. Maximum file size is 25 MB per upload.
- Focus mode selection: Switch to All Search or specific domains like Academic to improve the analysis results.
What the PDF Upload Feature Does in Perplexity Pro
Perplexity Pro can read text from uploaded PDF files and use that content as context for answering your questions. The feature works by extracting the text from the PDF and feeding it into the AI model alongside your query. This allows you to ask questions about the document’s content, request summaries, or extract specific data points.
To use the upload feature, you need an active Perplexity Pro subscription. The free tier does not support file uploads. You can upload one file per query. The file is processed on Perplexity’s servers and is not stored permanently. Each session retains the uploaded file for the duration of your conversation.
Steps to Upload a PDF and Analyze It
Follow these steps to upload a PDF and start analyzing it with Perplexity Pro.
- Open Perplexity Pro in a browser
Go to perplexity.ai and sign in with your Pro account. The interface shows a large text input box at the center of the page. - Click the paperclip icon
Look for the paperclip or attach icon on the left side of the text input box. Click it to open your file browser. - Select your PDF file
Navigate to the PDF you want to analyze. Select it and click Open. The file name appears above the text input box. Perplexity uploads the file automatically. - Choose a Focus mode
Below the text input, click the Focus button. Select All Search to let the AI use web sources alongside your PDF. For academic papers, choose Academic. For internal documents, choose Writing or Math. The Focus mode affects how the AI combines the PDF content with external sources. - Type your analysis question
In the text input, type a question about the PDF. For example, “Summarize this document in three bullet points” or “Extract all dates and deadlines from this contract.” - Press Enter or click the send icon
Submit the query. Perplexity processes the PDF text and returns an answer with citations from the document. You can ask follow-up questions in the same conversation.
Common Mistakes and Limitations When Uploading PDFs
The PDF upload feature works well for most standard documents, but some situations cause errors or poor results.
“The PDF is too large to upload”
Perplexity Pro limits file uploads to 25 MB. If your PDF exceeds this limit, reduce the file size by compressing images using a tool like Adobe Acrobat or Smallpdf. Alternatively, split the PDF into smaller parts using a PDF splitter and upload each part separately.
“The AI gives incomplete or wrong answers for scanned PDFs”
Scanned PDFs contain images of text, not selectable text. Perplexity cannot extract text from scanned pages. Use an Optical Character Recognition tool like Adobe Acrobat or Google Drive to convert the scanned PDF into a text-searchable PDF before uploading.
“The answer includes web sources instead of the PDF content”
This happens when you leave Focus mode on Automatic or Web. Switch to All Search or a domain-specific mode like Academic. This tells the AI to prioritize the uploaded file content over general web results.
“I cannot upload more than one file per query”
Perplexity Pro supports only one file per query. If you need to analyze multiple PDFs, upload one file, ask your questions, then start a new conversation for the next file. You can copy the AI’s answers from the first session before moving on.

If you work with contracts or research papers often, try the Pro subscription’s unlimited queries to process multiple documents in one session.
