Clean text copied
from a PDF.

CopyPrune is a free PDF text cleaner for text you have already copied. It repairs likely visual line wraps, line-ending word splits, ligatures, and hidden spacing, preserves explicit structure, and shows every recorded change in your browser.

Browser-only document handling

We do not intentionally send your pasted text to our servers, analytics, URLs, or local storage. Clear removes it from this page’s runtime state.

How careful cleanup works

How CopyPrune cleans
copied PDF text.

CopyPrune follows a deterministic set of readable rules. The cleaner protects obvious structure, makes only the repairs allowed by your mode and settings, and builds the proof report from the actual operations.

1

Paste the source

Copy selectable text from a PDF reader and paste it into the Source pane. The original remains untouched while you compare results.

2

Choose the restraint

Careful is the default. Standard joins more probable wraps. Flatten is available when you genuinely want one continuous block.

3

Inspect the report

See recorded wraps, repaired words, normalized glyphs, protected structure, and boundaries the careful mode declined to guess about.

Native before-and-after examples

Four common PDF copy problems.

The examples below describe what this browser utility is designed to handle. CopyPrune does not upload PDFs, perform OCR, or reconstruct a multi-column page.

01

Visual line wraps

Before
A printed page wraps text at a fixed
width even when the paragraph continues.
After
A printed page wraps text at a fixed width even when the paragraph continues.

Likely visual wraps become spaces; explicit blank-line paragraphs remain.

02

Split words

Before
The report demon-
strated a repeatable result.
After
The report demonstrated a repeatable result.

Likely end-of-line splits can lose the hyphen. Inspect recorded changes for legitimate compounds.

03

Lists and headings

2. Copy the result
After
NEXT STEPS
1. Review the text
2. Copy the result

Obvious structure is protected instead of being flattened into prose.

04

Ligatures and spacing

Before
The final file contains hidden spacing.
After
The final file contains hidden spacing.

Common PDF ligatures and invisible formatting characters become ordinary text.

Three modes

Use the least force that solves the problem.

Careful mode protects uncertainty. The stronger modes exist for messier source text, but they should receive more human review.

Recommended

Careful

Joins likely visual wraps, repairs likely split words, and protects explicit paragraph breaks plus enabled headings, lists, and structured rows.

Best for research notes and ordinary prose that you can review.
More active

Standard

Joins more single line boundaries while still protecting the clearest document structure. Its changes are labeled medium confidence.

Best when the copied paragraph is visibly fragmented.
Destructive structure

Flatten

Repairs likely split words when that rule is enabled, then replaces the remaining line and paragraph breaks with spaces. Line-break structure is intentionally removed.

Best only when one continuous text block is required.
What CopyPrune fixes—and what it cannot

What CopyPrune can
and cannot fix.

PDFs describe visual placement, not always the reading structure a writer expects. CopyPrune works after a PDF reader has already provided selectable text.

Your pasted text stays in this browser.

CopyPrune’s cleaning engine runs on your device. We do not intentionally send document text to our servers, put it in URLs, retain it in local storage, or include it in analytics events.

FAQ

Frequently asked questions about cleaning PDF text.

What does CopyPrune fix in copied PDF text?+

CopyPrune can repair likely visual line wraps and safer line-ending word splits, expand common ligatures, remove soft hyphens, and normalize selected hidden spacing. It protects explicit paragraphs, headings, lists, and structured rows when those protections are enabled.

How do I remove unwanted line breaks from copied PDF text?+

Use Remove Line Breaks Online when line wrapping is the only problem. The full PDF Text Cleaner can handle line wraps together with split words, ligatures, and hidden spacing.

How do I fix words split across PDF line breaks?+

Use Dehyphenate PDF Text to review individual line-ending hyphens and soft hyphens. The full cleaner can also repair likely split words and record each change for inspection.

Why does text copied from a PDF have broken line breaks?+

A PDF can store text as visually positioned page content rather than the logical paragraph structure a writer expects. When a reader exposes that text for copying, printed line endings and page-layout artifacts can come with it.

Can CopyPrune clean an uploaded PDF?+

No. CopyPrune intentionally accepts only text you have already copied. This avoids misleading promises about OCR, reading order, tables, and scanned pages.

Will it preserve every paragraph perfectly?+

No tool can recover every PDF’s intended structure from copied text alone. Careful mode protects blank-line paragraphs and obvious structure, then flags uncertain boundaries instead of silently joining them.

Does it use AI?+

No. CopyPrune uses deterministic browser-based rules. The same source, mode, and rule settings produce the same output and proof ledger.

Can I use confidential or regulated documents?+

CopyPrune does not claim compliance or suitability for confidential legal, medical, financial, or regulated information. Follow your organization’s data-handling requirements.
