Free URL Shortener – Single & Bulk Short Links

Q: Is the ConvertFree.net URL shortener free to use?

Yes. The URL shortener on ConvertFree.net is completely free to use for both single and bulk URL shortening. The site is supported by ads placed in dedicated ad slots, which keeps the interface clean and compliant with Google AdSense policies.

Q: How do I shorten multiple URLs at once?

Use the Bulk URL shortener section. Paste one URL per line into the textarea, upload a .txt file with one URL per line, or combine both methods. The tool processes up to 500 URLs at a time, skips invalid lines and generates a downloadable short-urls.txt file with all valid short links.

Q: What does the bulk download file contain?

The bulk result file is a plain text document. Each line contains the short URL followed by a tab and the normalized destination URL. This makes it easy to import the data into spreadsheets or analytics tools.

Q: Can I choose my own short codes?

Yes. In single mode you can enter a custom short code made of letters and digits. If the code is not already in use and meets the length requirements, the short URL will use your chosen code.

Turn long, messy links into clean short URLs you can share anywhere. Use the single mode for quick one-off links, or switch to bulk mode to shorten hundreds of URLs in one upload and download them as a handy text list.

Single URL shortener

Long URL

Paste any public URL. If you omit https://, we’ll add it automatically.

Custom short code (optional)

Bulk URL shortener (paste or upload .txt)

Paste URLs (one per line)

Each non-empty line will be treated as a separate URL. You can mix this with a .txt upload below.

Or upload .txt file

Choose .txt file One URL per line • Max 2 MB • Drag & drop supported

Bulk mode supports up to 500 URLs per request. Output includes a downloadable short-urls.txt file plus a copyable list of short links.

Free URL Shortener for Clean, Shareable Links

The ConvertFree.net URL shortener is built for real-world usage: social media links, campaign tracking, QR codes, email newsletters, and long URLs generated by CRMs or analytics platforms. Instead of pasting huge links that break in chat apps or overflow on mobile screens, you can turn them into short, stable URLs that are easy to share and remember.

Unlike many “free” link shorteners, this tool runs entirely on our own hosting. Every short link is stored in a simple, local mapping file and resolved directly from https://convertfree.net/url-shortener/?c=CODE. There are no external APIs, no hidden redirects chained through third-party tracking services, and no injected scripts that slow down your visitors. When someone clicks a short URL, they are sent straight to the destination you provided.

The single URL mode is perfect for quick day-to-day sharing. Paste a long URL, optionally choose a custom short code, and click Shorten single URL. You’ll instantly get a short link you can copy or open in a new tab. Custom codes let you create human-friendly links like ?c=spring-sale or ?c=resume that are easier to remember and reuse.

The bulk URL mode is designed for power users, marketers, SEO managers and agencies. You can paste up to 500 URLs at once or upload a .txt file with one URL per line. The tool validates each line, normalizes missing schemes to https://, and generates unique short codes for every valid address. All results are saved into a short-urls.txt file in a per-job storage folder and also displayed in a copyable textarea for quick use.

Because ConvertFree.net already provides a full suite of PDF tools and image converters, the URL shortener fits naturally into your workflow. You can convert and compress assets, upload them to your website or CDN, then generate short links for landing pages, lead magnets and download pages. It’s an easy way to keep your conversion tools and campaign links together in one place.

The code behind this URL shortener is deliberately simple and transparent: local PHP, no external conversion APIs, no database dependency and storage folders that are regularly cleaned by cron to remove old job files. This makes it friendly for Google AdSense and SEO: pages load quickly, metadata is clean, and the tool’s purpose matches the content users see in search results. Over time, that combination helps the URL shortener rank for terms like “free URL shortener”, “bulk URL shortener” and “shorten multiple URLs at once”.
