PDF إلى HTML

ماذا تفعل هذه الأداة

There are two ways to turn a PDF into a web page, and they suit different people, so both are here. Text mode writes headings, paragraphs, lists and links as real HTML: it will not look like the PDF, and that is the point, because it re-flows on a phone, it is searchable, and a screen reader can follow it. Page pictures mode renders every page as an image with the extracted text positioned invisibly over it - identical to the PDF, and close to useless on a small screen. Either way the result is one self-contained file.

Use text mode when a document has to be readable on a phone, indexable by a search engine, or usable with a screen reader - a policy, a manual, a report that people keep pinch-zooming. Use page pictures when appearance is the whole point and the file has to look like the original: a form, a certificate, a signed letter being shown rather than read.

كيف تعمل

1. Drop the PDF onto this page. In text mode the file is checked for a text layer first, and a scan is refused with a pointer to OCR PDF.
2. Pick the mode: text for a readable page that re-flows, page pictures for something that matches the original exactly.
3. Leave Complete HTML document and Put the styles inside the file on unless you are pasting the result into a page you already have.
4. In page pictures mode, set the resolution. 120 dpi is legible on screen; 200 dpi is sharper and roughly three times the bytes.
5. Press Convert to HTML and the single .html file downloads.

The output is one file with its stylesheet inlined, so it opens from a folder or an email attachment without the missing-stylesheet page that a linked CSS file produces. It is also written to stay readable with CSS switched off entirely. That is partly an accessibility property and partly a proof of what is underneath: markup that means something, rather than a heap of absolutely-positioned spans arranged to look right.

Text mode reads the page in one column. Multi-column layouts, sidebars and text boxes are flattened into a single reading order, which is the trade you are making in return for a page that works at 360 pixels wide.

In page pictures mode the images are embedded as data URIs rather than written as a folder of files next to the HTML. Base64 costs about 33 per cent over the raw bytes, which is worth paying for a file that can be mailed as one attachment. It does mean a long document at 200 dpi becomes heavy, so start at the default and raise it only if the result looks soft.

Rendering and text extraction both happen in your browser through PDF.js. Nothing about the document is transmitted, including in page pictures mode, where the images are produced on your own device rather than by a rendering server somewhere.
