Free Document Summarizer

Upload a Word document, PowerPoint file, TXT or ebook and get the key points in seconds. The tool reads the text in your file and produces a clear summary of the main argument or content. No account, no payment, nothing to install — upload and read.

Supported formats

The tool accepts PDF, DOCX, TXT, PPTX, EPUB and FB2 files up to 30 MB. For PDFs specifically — including questions about scanned files and text-layer requirements — see the PDF summarizer page. Everything else is covered below.

Word documents

DOCX is the format for reports, drafts, contracts, proposals and most documents produced in a professional or academic context. The tool reads the full text including headings, body paragraphs, footnotes and text inside text boxes. It does not read images, embedded charts or the content of fields that have not been updated.

For a long report with multiple sections, the summary follows the document's structure: it extracts the purpose stated at the start, the main findings or recommendations from the body, and the conclusion. Use the chat to pull out specific details — a number from section 3, the list of recommendations from the executive summary — without rereading the whole document.

Presentations

A PowerPoint deck typically carries its argument in the slide titles and the first bullet on each slide; the rest is speaker support. The tool reads exactly what is on the slides — titles, bullet points, notes if present — and produces a summary of the presentation's main points in sequence.

Slides built mostly from images or embedded videos with no text will contribute little to the output. A deck where the argument lives in the visuals rather than the text will produce a partial summary. For those, the most useful approach is to summarize the speaker notes rather than the slides.

Ebooks

EPUB and FB2 are the main ebook formats outside PDF. Both are supported up to 30 MB. An ebook summary covers the main argument or narrative arc at a high level — what the book is about, what it argues or describes, and how it concludes. For a detailed chapter-by-chapter breakdown, use the chat after the summary: "Summarize chapter 4" or "What does the author argue in the second half?"

Ebooks formatted with complex layouts — heavily illustrated cookbooks, graphic novels, textbooks with many sidebars — will produce less complete summaries than prose-heavy books, because the text layer carries less of the content.

TXT files

Plain text files work straightforwardly: all the content is text, so there is nothing the tool cannot read. TXT is the most reliable format when you want a complete, accurate summary with no formatting complications.
