Convert Cookies Between Formats Instantly

Convert cookies online into different formats like Netscape, JSON, Set-Cookie, CSV, or SQLite. The tool works fast, free, and secure — directly in your browser without uploading any data.

How It Works

  1. Upload your cookie file (supports .cookies, .http-request, .set-cookie, .keyvalue, .tsv, .txt, .json, .csv, .db)
  2. Select the format you want (for example: Netscape to JSON, CSV to Set-Cookie)
  3. Click Convert and download your new file instantly
  • Netscape (.txt) – import or export cookies in browsers and tools
  • JSON (.json) – store structured cookies for Chrome, Firefox, and developer tools
  • HTTP Request (Cookie) – send cookies in request headers
  • HTTP Response (Set-Cookie) – receive cookies from servers
  • Key=Value – save cookies in simple one-per-line format
  • CSV (.csv) – open cookies in spreadsheets for easy analysis
  • TSV (.tsv) – use tab-separated cookie data for Unix tools
  • SQLite (.db) – store cookies in browser databases like Chrome’s Cookies.db
  • cURL jar – keep cookies for API calls and automation
  • Custom (.cookies) – handle app-specific cookie formats

Features

  • Convert cookies 100% free
  • Run the tool without installation or signup
  • Use it in Chrome, Firefox, Edge, and other browsers
  • Convert cookies in seconds

Why Use This Tool?

Browsers, APIs, and extensions require cookies in specific formats.
Save time and avoid errors by using this cookie conversion tool. Convert Netscape cookies to JSON, Set-Cookie headers to CSV, or export cookies from Chrome and Firefox into the format you need with one click.

Netscape Cookies (.txt)

The Netscape format stores cookies in plain text with tab-separated fields such as domain, path, expiry, and value. Many browsers, cURL, and extensions still use this format.

JSON Cookies (.json)

JSON cookies store data in key-value pairs inside an array. Chrome and Firefox export cookies in this format, and developers use it because it is easy to read and process.

HTTP requests send cookies in the format:
key=value; key2=value2;
Use this format in API clients like Postman or when you run curl commands with headers.

Servers send cookies in HTTP responses with the Set-Cookie header. Each cookie includes details like expiry date, Secure, and HttpOnly flags. Developers parse this format when they debug server responses.

Key=Value

This format saves cookies one per line:
name=value
You can copy and paste these cookies quickly into scripts or tools.

CSV Cookies (.csv)

CSV cookies store data in comma-separated rows. Open them in Excel or Google Sheets to view columns like name, value, domain, path, and expiry.

TSV Cookies (.tsv)

TSV cookies use tab-separated values. This format works better with Unix tools and text editors because it avoids issues with commas in cookie values.

SQLite Cookies (.db)

Browsers like Chrome, Edge, and Opera save cookies in SQLite databases (Cookies.db). This format supports structured queries and fast lookups but requires a database reader.

cURL Jar

The cURL cookie jar stores cookies in the Netscape format. Use it to persist cookies across multiple requests in API automation or web scraping.

Custom Cookies (.cookies)

Some extensions and apps save cookies in .cookies files. These files may contain JSON, text, or other structures. This tool converts them into standard formats automatically.
