Summarize PDF
Get a faithful AI summary in seconds. You pick the provider, you bring the key — imisspdf never sees the file.
Unlike our other tools, this one sends your document content to the AI provider you choose (OpenAI, Anthropic, Google, or your own Ollama server). Your key and your file content never touch our servers — the request goes directly from your browser to the provider you pick. Don't use for documents that can't go to any third party.

What "Summarize PDF" does on this page
Summarize PDF turns a long document into a short readable summary. You drop in a PDF, the page extracts its text locally, picks a length (short / medium / long), and sends a single prompt to the AI provider you choose. The model writes back neutral prose — no bullets, no markdown, no "Summary:" labels — and we display it. You can copy it as text or download it as a Word document.
We are deliberate about scope. The AI is instructed to summarise the document faithfully, not to opinionate or fill in gaps from general knowledge. If something isn\'t in the source, it won\'t appear in the summary. If the document is very long, we tell the user upfront that only a clipped view was sent.
Why BYOK
Most online "AI summarise PDF" services route the call through their own server with their own LLM key, and charge a subscription. That model means their server sees the document on the way to the AI. We don\'t want to be that server. You bring your own key from OpenAI, Anthropic, Google AI Studio, or your own Ollama install, the request goes directly browser → provider, and imisspdf is uninvolved. For users who want zero cloud, Ollama is the answer.
Privacy & security
Your API key lives in localStorage on your device. Document text plus the summarise prompt travel from your browser to api.openai.com / api.anthropic.com / generativelanguage.googleapis.com / your local Ollama. imisspdf serves the HTML and JS once and is then out of the loop. To wipe your saved keys, click "Forget all keys" or clear site data.
Frequently asked questions
No. The PDF text and your key go DIRECTLY from your browser to whichever AI provider you pick. imisspdf is not in the request path — there is no proxy, no relay. Your key sits in localStorage on your device and you can wipe it whenever.
Short = roughly one paragraph (~80 words). Medium = three paragraphs (~250 words). Long = five paragraphs (~500 words). The AI is instructed to write neutral, faithful prose — no opinions, no information from outside the document, no markdown bullets.
You pick. By default we ask the AI to use the same language as the document. You can override that — for example, summarise a Japanese PDF in English, or an English PDF in Bahasa Indonesia. The AI handles the translation internally.
For very long documents we truncate to roughly the first ~75% and the last ~25% of the text to stay within model input limits. The summary will reflect that. You'll see a note in the result if truncation kicked in.
Yes — you can copy the text directly or download it as a .docx Word document. The .docx wraps the summary with the original filename as the heading.
