What is PDF to HTML?
PDF to HTML is the process of converting the content of a PDF document into HTML page code. The resulting HTML file can be opened directly in a browser, or embedded into websites, blogs, knowledge bases, and other web pages.
**Difference from PDF to Word:** Word is better suited for further editing and layout adjustments, while HTML is better for publishing directly on websites or embedding as web content.
**Prerequisite:** This page works on text-based PDFs (PDFs where text can be selected and copied directly). For scanned PDFs, since they contain no selectable text, layout and text recognition after conversion will be poor — please run OCR first.
**Workflow:** Upload PDF → server-side asynchronous conversion → download the single HTML file once conversion is complete.
Use Cases
- Publish product manuals, white papers, and reports from PDF onto a company website or blog
- Convert PDF content into HTML for knowledge bases such as Notion, Confluence, or Yuque
- Send a PDF as the HTML body of an email to avoid PDF reader compatibility issues
- Turn a PDF into a web preview version so customers can browse it quickly without downloading
- Convert PDF teaching materials and handouts into web pages for easier online reading and sharing
How to Use
- Upload one PDF file to convert (single-file processing).
- If the PDF has an open password, enter it in the password field and start the conversion.
- Wait for the server-side asynchronous conversion to complete — keep the page open to track progress or download later from history.
- Download the resulting HTML file once conversion is complete.
Features
- Layout preserved: titles, paragraphs, lists, and tables are converted into the matching HTML tags based on the PDF structure
- Text styles preserved: basic styles such as font size, font, bold, and alignment are kept in the HTML
- Server-side async processing: no need to stay on the page after submitting — download the result from history
- Supports encrypted PDFs: enter the open password when uploading a password-protected PDF to proceed
- Cancellable tasks: queued or running conversions can be cancelled manually
- History: recent tasks are saved automatically so you can re-download them later
Best Practices
Make sure the PDF is text-based before submitting
Being able to select and copy text directly in a PDF reader means it's a text-based PDF, which converts far better than scanned/image-only PDFs. Image-only/scanned PDFs require OCR first.
Always enter the password for encrypted PDFs
If you do not provide the open password during conversion, the server cannot read the PDF content and the task fails. Set the password field before submitting.
Submit large batches in smaller groups
Only one PDF is processed at a time — evaluate which files truly need HTML form and submit them individually to avoid occupying the queue.
Evaluate compliance first for sensitive files
This tool uses server-side conversion and the PDF is sent to the server; for files involving personal privacy, trade secrets, or compliance restrictions, use a local-processing solution instead.
If the target is Markdown or Word, use the corresponding tools directly
Avoid double conversion from HTML which can cause content loss. Use the dedicated PDF→Markdown or PDF→Word tools when those formats are the end goal.
FAQ
Which file types are supported?
Only PDF files are supported. Only one PDF can be uploaded at a time. The single-file size is limited by this tool's general file size limit; if your file exceeds it, please compress or split it first.
Can I process multiple PDFs at once?
This page processes only one PDF at a time. If you have multiple files to convert, please submit them one by one; once submitted, you can view and download each from history.
Can a scanned PDF be converted to HTML?
Results are limited. Scanned PDFs are made up of images and contain no selectable text, and this tool does not perform dedicated OCR on them. If you really need to convert one, we recommend using a dedicated OCR tool to recognize it as a text-based PDF first and then uploading.
Can the converted HTML be published directly on a website?
Yes. The converted HTML file uses standard web page code and can be previewed directly in a browser; to publish it on rich-text editors such as WordPress or Notion, we recommend pasting the HTML source into the editor's source or HTML mode.
Will the file be uploaded to a server?
Yes. This tool uses server-side asynchronous conversion — the PDF is sent to this tool's server for processing and the HTML result is returned once conversion is complete. After processing, the server cleans up intermediate files according to its established policy. If you are privacy-sensitive, please first evaluate whether this processing approach meets your compliance requirements.
Can the conversion be cancelled?
Yes. While the task is queued or running, you can click the cancel button on the page to stop it; after cancellation, no downloadable result is produced.
How long does conversion take?
It depends on the number of pages, the file size, and the current server queue. A typical PDF usually finishes within seconds to a minute or two; during busy times it may take longer. After leaving the page, you can check the task status in history.
Will the converted HTML work in WordPress / Notion?
It can be used, but the result depends on the target platform's HTML sanitization rules. Paste the HTML source into the editor's "HTML / Source" mode and save; if the platform filters out styles, some layout may need to be fine-tuned in the editor.
Why are there no Markdown / ZIP / multi-format options?
This page outputs only a single HTML file and does not offer Markdown, Jupyter, ZIP bundles, or multi-file output. If you need those formats, please see our other tool pages such as PDF to Word or PDF to TXT.
Troubleshooting
Submission stays queued or processing for a long time
Possible causes: 1) The server queue is currently busy — please wait or check history later. 2) A network issue interrupted polling — refresh the page and you can still continue checking from history.
Styles are lost in the converted HTML
Possible causes: 1) The original PDF itself lacks explicit style information. 2) The HTML was sanitized when pasted into the target editor — paste into source mode, or download the HTML file and open it directly in a browser to check.
No text or garbled text in converted scanned PDFs
Scanned PDFs contain no selectable text and this tool does not provide OCR. If conversion is required, please first use a dedicated OCR tool to recognize the file as a text-based PDF and resubmit.
File exceeds the size limit
The single-file size is limited by this tool's general cap. Please first use PDF Compress or PDF Split to reduce the size before uploading.
Glossary
- HTML
- HyperText Markup Language, the standard structural language of web pages. This tool outputs an HTML file that can be opened directly in a browser.
- Text-based PDF
- A PDF in which text is stored as selectable characters (it can be copied and pasted directly). This tool converts this kind of PDF with better results.
- Scanned PDF
- A PDF made up of images where text cannot be selected directly. This tool has limited support for it — run OCR first.
- Server-side conversion
- The PDF file is sent to this tool's server, where the server completes the conversion asynchronously and returns the result file.
- Asynchronous task
- After submitting a PDF, the task enters a server queue. While conversion is in progress, you can check progress, cancel the task, or leave the page and re-download later from history.
