Do you fetch or open the URL?

No. This validator only parses the URL string locally. It does not make network requests, follow redirects, resolve DNS, or check status codes.

Why is example.com invalid?

The tool expects a full absolute URL with http:// or https://. Use https://example.com when a CMS, API, webhook, or sitemap requires an absolute web URL.

Can I validate mailto, tel, ftp, or app deep links?

No. This page is intentionally limited to HTTP and HTTPS web URLs. Other schemes need different validation rules.

Is my private URL stored?

No. Validation runs in your browser only. URLs are not uploaded, logged, stored, or shared.

URL Validator & HTTP Link Parser

Validate HTTP and HTTPS URLs locally, parse host/path, and catch malformed links before publishing, importing, or sending them to APIs.

Results

Paste input and validate locally.

Status: Ready when you validate.
Details: Ready when you validate.
Host: Ready when you validate.
Path: Ready when you validate.

How to use this validator

Paste the full URL exactly as it will be published or sent to another system.
Run validate to parse the protocol, host, and path locally.
If invalid, add the missing protocol, encode spaces/special characters, or replace unsupported schemes.
After the structure passes, use browser/network tools separately if you need to verify redirects, SSL, or live page availability.

Rules & checks

Uses the browser URL parser to catch malformed absolute URLs.

Accepts http:// and https:// schemes; other schemes such as ftp:, mailto:, tel:, and javascript: are rejected by this tool.

Requires a full absolute URL with protocol and host, not a bare domain or relative path.

Returns the parsed host and pathname when the URL is structurally valid.

Does not fetch the URL, follow redirects, resolve DNS, check certificates, or verify page content.

Inputs explained

URL
Paste one full link including http:// or https://. Use it for redirect targets, canonical URLs, webhook callback URLs, CMS fields, sitemap rows, CSV imports, and API payloads where relative paths or protocol-less domains would break downstream systems.

When to use it

Validate redirect targets before deploying a redirect map or migration spreadsheet.
Check webhook callback, OAuth redirect, and API endpoint URLs before saving settings.
Clean CMS, product, affiliate, and directory-import URLs before publishing at scale.
Review canonical, Open Graph, sitemap, and manifest URLs while debugging web metadata.
Catch malformed URLs found in HAR/network logs before handing them to backend or QA teams.

Common errors

Missing http:// or https:// protocol on a domain-only link.
Relative paths such as /pricing or ../docs entered where an absolute URL is required.
Spaces, smart quotes, unescaped brackets, or copied punctuation inside the URL.
Unsupported schemes such as mailto:, tel:, ftp:, file:, chrome:, or javascript:.
Pasted Markdown or HTML around the URL instead of the raw URL value.

Limitations

Format-only validation; it does not load the URL or prove that the page exists.
Does not follow redirects, check status codes, verify SSL certificates, inspect robots/canonicals, or test page speed.
Only accepts http and https web URLs; non-web schemes need a separate validator.
Returns host and path, but does not normalize query parameters or decide whether tracking parameters should be kept.

Tips

Prefer https:// for production-facing pages, canonical URLs, API callbacks, and webhook endpoints.
Trim leading/trailing whitespace before validating user-entered links.
Encode spaces as %20 or use URL-safe slugs instead of copying labels with spaces into a path.
Normalize trailing slashes and lowercase hosts according to your app's routing rules after validating structure.
Pair this with the Open Graph, favicon, manifest, and HAR validators when QAing a public web page launch.

Examples

Valid HTTPS page URL

https://example.com/blog/post?utm_source=newsletter -> Valid URL (host=example.com, path=/blog/post)
Useful before putting campaign links into email, CMS buttons, or import sheets.

Bare domain missing protocol

example.com/pricing -> Invalid until https:// or http:// is added.
Many APIs and webhook settings require absolute URLs, not domain-only strings.

Unsupported URL scheme

ftp://example.com/file.zip -> Invalid for this validator because it only accepts http/https web URLs.
Use a custom scheme validator if you need mailto:, tel:, deep links, or file transfer URLs.

Deep dive

This URL validator checks HTTP and HTTPS links locally so malformed web URLs are caught before they reach a CMS, redirect file, sitemap, webhook, or API payload.

Use it to confirm the protocol, host, and path are structurally valid while keeping unpublished links, staging URLs, and private callback URLs on your device.

Because the tool never fetches the URL, it is safe for quick format checks on internal, staging, or not-yet-live links—but live availability still needs a separate crawl or browser test.

URL validation runs entirely in your browser. Pasted links, staging URLs, callback URLs, tokens in query strings, and internal hostnames are not uploaded, fetched, logged, stored, or sent to a server.

This is a local structural URL check. It does not verify that the destination exists, is reachable, uses a valid certificate, returns a 200 status, or has correct SEO metadata.
