pinterest-url-normalizer

pinterest-url-normalizer

Parse, classify, and normalize Pinterest URLs without making network requests.

Source code

The package recognizes Pin, pin.it, profile, board, and Ideas URLs across Pinterest country domains. It uses an exact host allow list, rejects HTTP URLs and lookalike domains, and removes tracking parameters from normalized output.

Install

npm install pinterest-url-normalizer

JSR users can install the same TypeScript source package with:

npx jsr add @savepinner/pinterest-url-normalizer

Usage

import {
  isPinterestUrl,
  normalizePinterestUrl,
  parsePinterestUrl,
} from "pinterest-url-normalizer";

const parsed = parsePinterestUrl(
  "https://de.pinterest.com/pin/987654321/?utm_source=share",
);

console.log(parsed.kind); // "pin"
console.log(parsed.pinId); // "987654321"
console.log(parsed.normalizedUrl);
// https://www.pinterest.com/pin/987654321/

isPinterestUrl("https://pin.it/AbC123"); // true
normalizePinterestUrl("https://pinterest.co.uk/savepinner/media-tools/");
// https://www.pinterest.com/savepinner/media-tools/

Supported URL kinds

Kind	Example
pin	https://www.pinterest.com/pin/123456789/
short	https://pin.it/AbC123
profile	https://www.pinterest.com/savepinner/
board	https://www.pinterest.com/savepinner/media-tools/
ideas	https://www.pinterest.com/ideas/space-wallpaper/926295399832/

pin.it links are classified and normalized but are not followed. Resolving them requires a network request and belongs in the consuming application.

API

parsePinterestUrl(input)

Returns a discriminated object with kind, originalUrl, normalizedUrl, and type-specific fields. Throws PinterestUrlError with code INVALID_URL or UNSUPPORTED_URL when parsing fails.

normalizePinterestUrl(input)

Returns the canonical URL. Full Pinterest URLs use www.pinterest.com; short links retain pin.it because resolving them requires network access.

isPinterestUrl(input)

Returns true when the value is one of the supported URL forms.

isPinterestHost(host)

Checks a hostname against the package's exact Pinterest country-domain allow list.

Why this package exists

This parser is maintained by the team behind the Pinterest image downloader, a browser tool for inspecting media exposed by public Pinterest Pin URLs. The package contains no downloader, tracking, browser automation, or remote code.
