Extract Text from PDF

Client-Side PDF Plain Text Stream Extraction and Page Inspection

Copying passages, citations, or raw text out of multi-page PDF reports by hand often introduces broken line wraps and misses pages that contain flat scanned images. PDF to Text extracts digital text streams from PDF documents page-by-page directly inside your web browser without uploading files to external servers.

When a file is selected, the validator checks the `%PDF-` header, verifies that the document is not password-encrypted, and enforces a 100 MB client-side memory limit. The extraction engine then reads each page's positioned text items, starts a new line whenever the vertical baseline coordinate shifts by more than `5` points (`|currentY - lastY| > 5`) or an end-of-line marker is reached, and normalizes excess whitespace by collapsing three or more consecutive blank lines into a clean paragraph break.

Inside the `Extracted Plain Text Stream` viewer, you can filter lines in real time using `Search in Text`, isolate individual pages with the `Target Page View` selector (which automatically synchronizes the `Document Inspection Live Preview` below), and inspect word, character, and scanned-page counts. Clicking `Copy Text` or `Download .txt` exports either the entire document (`<filename>-text.txt`) or the currently selected page (`<filename>-page-<N>.txt`).

Core Tool Capabilities

• Vertical Delta Line and Paragraph Reconstruction: Evaluates the vertical transformation matrix coordinate (`Y`) of every glyph run on each page. Runs within `5` vertical points are joined onto the same horizontal line, while vertical shifts exceeding `5` points trigger a line break and redundant blank lines are compressed to preserve natural paragraph spacing.
• Automatic Scanned-Page Detection and Alerts: Flags any page containing fewer than `3` extracted words and fewer than `3` text items as a likely raster scan. When image-only pages are detected, the workspace displays a `Scanned Pages Detected` warning banner and inserts a clear placeholder notice in the full-document text stream indicating that OCR is required.
• Real-Time Keyword Line Filtering: Type any keyword or phrase into the `Search in Text` input (`Filter text lines`) to filter the monospaced viewer down to matching lines in real time. A live badge inside the search bar reports the exact number of matching lines (`<N> match` or `matches`).
• Target Page View and Synchronized PDF Preview: Use the `Target Page View` dropdown to switch between `All Pages (<N> pages)` and any individual `Page <N> (<words> words, <chars> chars)`. Selecting a specific page isolates its text stream in the viewer and jumps the `Document Inspection Live Preview` card to that exact page.
• Full-Document or Single-Page UTF-8 Export: Click `Copy Text` to copy the active view to your system clipboard, or click `Download .txt` to save a UTF-8 plain text file. Exporting in `All Pages` view saves `<filename>-text.txt` with page divider headers, while exporting a filtered single page saves `<filename>-page-<N>.txt`.
• Live Word, Character, and Page Metrics: Displays total extracted words, normalized Unicode character counts, scanned-page totals, and file byte size across the `Extracted Plain Text Status` summary header and the bottom document inventory table.
