PDF to HTML keeps the words, not the page design
HTML is useful when the words from a PDF need to go on a web page.
You get the extractable text wrapped as simple HTML. It is not a pixel copy of the PDF.
Scans and columns in this PDF file
Complex layouts collapse into paragraphs. Keep the PDF if the design matters.
If the page has to look identical, send the PDF. More PDF jobs are grouped on the PDF tools page.
Why PDF to HTML is its own job
PDF to HTML sits on this site because PDF and HTML are not interchangeable, even when they look similar in a file list. HTML is useful when the words from a PDF need to go on a web page. Application portals, email, and print shops still ask for PDF in 2026, often with a size cap. Writers move HTML into a CMS, or wrap extracted text so a browser can show it.

The PDF file you already have
PDF keeps a page looking stable on most screens. It is the file offices send when the reader should not casually reflow the layout. A scan or a photo of a page has no text layer until OCR runs, and OCR is only as good as the image.
Keep the PDF if anyone might need the original page look, because extracts drop columns and images.
What a HTML result is for
The download has to be HTML, because that is the format the next step named. Writers move HTML into a CMS, or wrap extracted text so a browser can show it. Headings and paragraphs survive when the source was simple.
Expect a readable page, not a screenshot of the original document.
How to tell that PDF to HTML worked
PDF to HTML is worth using only when HTML is what the next step actually named. HTML is useful when the words from a PDF need to go on a web page. What you get from PDF to HTML: You get the extractable text wrapped as simple HTML. It is not a pixel copy of the PDF. Before you trust it: Complex layouts collapse into paragraphs. Keep the PDF if the design matters. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. A second pass rarely helps. If the first HTML file is rejected, read the error from the program that rejected it. Another conversion of a bad result usually makes the file worse, not more compatible. When you are done, you should still have the PDF original and one HTML download that you have opened. If those two are the same kind of failure, this was the wrong tool and the page above is the place that says so. A PDF page can be text, a scan, or a picture of a design. PDF to HTML does one of those jobs, not all of them. If you needed editable sentences, a text extract is the right family. If you needed the page to look identical, send the PDF or export from the app that built it. Open the download before you throw away the original.
Here is the decision for PDF to HTML. You start with PDF and you stop when a real program accepts HTML. A PDF exported from Word or a browser usually has a text layer, so the words can be copied. It is a poor way to preserve a print layout, scripts, or a designed brochure. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

Other jobs start from the homepage, where each tool is named for the conversion it actually does.
