How does CSV bulk shortening work?
You upload a spreadsheet of URLs, and RELURL shortens them all at once, returning a list of short links you can export.

Bulk URL Shortener from CSV
Upload a CSV of URLs and shorten them all at once. Create many short links in a single batch, with each one automatically generated and ready to export.
Shortening one link at a time is fine for a couple — but when you have hundreds, it's brutal. RELURL's bulk URL shortener from CSV ends the grind. You prepare a spreadsheet with your URLs, upload it, and RELURL shortens every one in a single batch. Each URL gets its own new short link, and the completed list is ready to export. For teams handling large link sets — migrating content, preparing campaigns, or organizing big libraries — bulk shortening turns hours of clicking into minutes. It's the fast, reliable way to process high-volume URLs without losing your mind.

What Makes RELURL Different
RELURL is designed to handle scale, and bulk CSV shortening is central to that. Instead of slowing down as your link list grows, you batch through it in one upload. Most tools expect you to click your way through each URL; RELURL lets you work the way teams actually do — at scale. For anyone moving or organizing a large collection of links, bulk shortening is the difference between a tedious chore and a fast, finished job.
How We Compare to Alternatives
Some tools only shorten one URL at a time. RELURL processes an entire CSV in a single batch.
Manual link creation wastes hours on big lists. RELURL generates them all automatically.
Preparing campaign links at scale is a chore elsewhere. RELURL makes bulk output clean and exportable.
