Extracting URLs from text is essential for link auditing, research, and content analysis. Whether reviewing documents for broken links, gathering resources, or analyzing web content, finding all URLs quickly saves significant time. Our URL Extractor finds and lists all links in any text instantly.
What is URL Extraction?
URL extraction identifies and isolates web addresses from mixed text content. The process recognizes various URL formats including HTTP, HTTPS, FTP, mailto, and other protocols.
Extracted URLs form organized lists ready for validation, analysis, or further processing.
Why Extract URLs?
URL extraction serves critical purposes across many workflows:
- Link auditing: Inventory all links for migration or SEO reviews
- Research collection: Gather referenced resources from documents
- Security review: Identify potentially malicious links in emails
- Content analysis: Understand what sources a document references
- Archiving: Capture all resources referenced before content expires
Common Use Cases
Email Analysis
Marketing emails and newsletters contain multiple links. Extraction reveals all destinations for campaign tracking and verification. Security teams extract links from phishing reports to identify malicious domains.
Document Review
PDFs, Word documents, and presentations embed URLs in text. Extraction creates lists for validation and updating. Legal teams extract citations and references from contracts for due diligence.
Code Auditing
Source code contains API endpoints, configuration URLs, and resource links. Extraction identifies external dependencies. Security auditors extract URLs to verify connections to approved services only.
Web Content Analysis
HTML source contains outbound links for SEO analysis. Extraction enables comprehensive link profiling. Digital marketers analyze competitor link structures through URL extraction.
Academic Research
Research papers reference numerous online sources. Extract all citations for bibliography compilation and source verification. Librarians extract URLs to check for link rot in digital archives.
Compliance and Monitoring
Regulatory content may require all external links to be documented. Compliance teams extract URLs from published materials for audit trails.
Extract URLs Instantly
Need to find all links in your content? Our URL Extractor identifies every URL format and creates a clean list instantly. Paste your text, click extract, and copy the results.
The extractor handles:
- Full URLs: Complete addresses with protocols (https://example.com)
- Query strings: URLs with parameters (page?id=123)
- Fragments: URLs with anchors (page#section)
- All protocols: HTTP, HTTPS, FTP, mailto, tel, and more
URL Formats Recognized
Standard Web URLs
Full URLs with http:// or https:// protocols are the most common format. The extractor captures complete paths including subdomains.
Protocol Variations
Different protocols serve different purposes:
- http:// and https://: Web pages and resources
- ftp://: File transfer protocol links
- mailto:: Email address links
- tel:: Phone number links
Complex URLs
The extractor handles URLs with ports (example.com:8080), IP addresses (192.168.1.1), and percent-encoded characters (%20 for spaces).
Advanced Techniques
Master URL extraction with these professional approaches:
Pre-Processing for Better Results
Before extraction, normalize line breaks and remove word-wrap artifacts. Long URLs split across lines extract as fragments. Use Join Lines to reconnect wrapped URLs before extracting.
Protocol-Specific Extraction
Sometimes you only need certain URL types. After extraction, filter results for specific protocols. Extract all URLs, then filter for "https://" only to find secure links.
Domain Grouping
After extraction, parse URLs to extract domains. Group URLs by domain to understand link distribution. This reveals which external sites receive most references.
Tracking Parameter Removal
Marketing URLs often include tracking parameters that create duplicates. After extraction, use Find and Replace to strip UTM parameters for cleaner deduplication.
Batch Processing Documents
When analyzing multiple documents, extract URLs from each separately, label by source, then combine for comprehensive analysis. This preserves context about where each URL appeared.
Common Mistakes to Avoid
These extraction errors produce incomplete or incorrect results:
- Missing protocol-less URLs: Some text contains URLs without http:// prefix. Configure extraction to recognize domain patterns like "example.com" even without protocols.
- Including false positives: Version numbers (v1.2.3) and file paths can match URL patterns. Review extracted lists for non-URL content that slipped through.
- Losing URL components: Extraction may truncate at special characters. Verify that query strings (?param=value) and fragments (#section) remain intact.
- Not handling encoding: URLs with encoded characters (%20, %3A) may extract incorrectly. Ensure your extractor preserves percent-encoding.
- Breaking wrapped URLs: Text formatted with line breaks splits long URLs. Pre-process to remove artificial line breaks before extraction.
Code Examples for Developers
Implement URL extraction programmatically:
JavaScript:
// Extract all URLs
const urlRegex = /https?:\/\/[^\s<>"{}|\\^`\[\]]+/g;
const urls = text.match(urlRegex) || [];
// Extract and deduplicate
const uniqueUrls = [...new Set(text.match(urlRegex) || [])];
Python:
import re
# Extract all URLs
url_pattern = r'https?://[^\s<>"{}|\\^`\[\]]+'
urls = re.findall(url_pattern, text)
# Extract and deduplicate
unique_urls = list(set(urls))

Processing Extracted URLs
Deduplication
Documents often link to the same URL multiple times. Use Remove Duplicates to create a clean, unique list.
Sorting
Organize extracted URLs alphabetically or by domain using Sort Lines for easier review and analysis.
Filtering
Focus on specific domains or protocols using Filter Lines to segment your URL list.
Validation
After extraction, verify URLs return successful responses. Identify 404s, redirects, and broken links.
Extraction Challenges
Partial URLs
Text may contain URLs without protocols. "example.com" might be a link depending on context. Extraction tools must balance accuracy.
URL-like Text
Version numbers (v2.0) and file paths can resemble URLs. Good extraction filters false positives while capturing real links.
Wrapped URLs
Long URLs wrapped across lines in plain text may extract as fragments. Source formatting affects extraction accuracy.
Post-Extraction Analysis
After extraction, analyze your URL list:
- Domain counting: Identify which external sites are referenced most
- Protocol review: Verify all links use HTTPS where required
- Link checking: Test each URL for accessibility
- Categorization: Group by domain, type, or purpose
