About

This tool functions as a client-side bridging utility that transforms dynamic web content into static Portable Document Format (PDF) files. Unlike standard browser print dialogs, which often retain digital debris (ads, navigation bars), this converter offers a sanitized rendering pipeline. It empowers users to preserve information in a high-fidelity, offline-accessible format.

The engine utilizes a Virtual DOM extraction process, allowing for the manipulation of HTML nodes before rasterization. This enables features like the "Element Zapper", which surgically removes unwanted DOM elements, and custom CSS injection for typographic overrides. All processing occurs within the browser sandbox (or via secure CORS proxies), ensuring data privacy.

Technical precision is paramount. The tool calculates viewport dimensions based on target paper density, defined as D = 96 PPI for screen-to-print mapping. It handles complex pagination logic, preventing element shearing across page breaks by analyzing the computed height h of block-level elements relative to the Page_height.

Formulas

The conversion process relies on precise mapping between screen pixels and physical print dimensions. The fundamental rasterization formula for page height in pixels depends on the target DPI (Dots Per Inch).

{

H_px = H_in × DPItypically DPI = 96 (CSS standard)

When resizing images to fit constraints, the Aspect Ratio (AR) must be preserved to prevent distortion:

W_new = W_origH_orig × H_target

To estimate the final file size (S) of the generated PDF blob:

S ≈ n∑i=1 (Img_i × Q) + (C_text × 1B) + K_overhead

Where Q is the JPEG quality coefficient (0.0 ≤ Q ≤ 1.0) and C_text is the character count.

Frequently Asked Questions

Many modern websites enforce Strict Content Security Policies (CSP) or X-Frame-Options that block external rendering. Additionally, "lazy loading" images may not render if the scroll simulation fails. For best results with complex sites, copy the raw HTML source and use the "Raw HTML" input mode.

Yes. The rendering engine operates primarily within your browser's memory using a Virtual DOM. If you use the "Fetch URL" feature, the request is routed through a CORS proxy to bypass browser security restrictions, but the data is not stored permanently on any server.

The Zapper injects a mouseover event listener into the preview container. It identifies the target DOM node and applies an inline style of `display: none !important` when clicked, removing it from the render tree before the PDF generation phase.

Currently, the tool supports DOM element removal (Zapper) and styling overrides (CSS). Direct text editing is not supported in this version to maintain document integrity, but you can modify the source HTML in the "Raw HTML" tab.

A quality setting of 0.7 to 0.8 offers the best balance between visual fidelity and file size. Settings below 0.5 will result in noticeable compression artifacts, while 1.0 creates significantly larger files without perceptible screen benefits.
