Bulk URL Shortener: Shorten 100 Links at Once (Paste or CSV)

# Bulk URL Shortener: Shorten 100 Links at Once (Paste or CSV)

Shortening one link takes about ten seconds. Shortening two hundred links one by one takes your whole afternoon — and it is exactly the kind of repetitive work that produces typos, missed UTMs, and links pasted into the wrong row. That is what a bulk URL shortener is for: you feed it a list of long URLs and get back a matching list of short links in one pass, with click tracking on every single one.

This guide covers the three ways to shorten links in bulk — pasting a list, importing a CSV, and calling an API — shows you exactly how to do each one on Urlzbit, and compares what bulk shortening actually costs on the major tools. All competitor prices below were checked in October 2026.

One honest note up front: on Urlzbit, bulk paste and CSV import are Pro features at $9 per 30 days. If you only shorten a handful of links at a time, the free plan covers you one link at a time — up to 100 saved links, with 10,000 clicks a month.

What counts as "bulk" — and the three methods

"Bulk" is not a technical term. In practice it means more links than you want to shorten by hand, which for most people is somewhere around ten. Every bulk shortener handles that with one of three methods, and each one fits a different job.

• Paste a list: copy a column of URLs from your spreadsheet, paste it into one box, and get back the same number of short links. This is the fastest option for one-off jobs — a product launch, a newsletter link list, a batch of affiliate URLs. Most tools cap the paste size; on Urlzbit, bulk paste handles up to 20 URLs per batch on the Pro plan.
• Upload a CSV: for jobs too big for a paste box. A CSV file holds your long URLs in one column, optionally with custom endings in a second column. The tool reads the file, shortens every row, and hands you back a results file. This is the method for hundreds of links — seasonal catalogs, site migration lists, affiliate product feeds — and it leaves you an audit trail.
• Call an API: for recurring or automated jobs. Instead of doing the work yourself, your code (or an automation tool like Zapier or Make) sends URLs to the shortener and gets short links back. Powerful, but it is always a developer feature — and on most hosted shorteners, including Urlzbit, it is a paid feature.

Method 1: paste up to 20 URLs at once

Pasting is the method you will use most. Here is the full walkthrough on Urlzbit:

• Log in and open Try the free shortener: urlzbit.pro — the bulk option is in your dashboard.
• Choose bulk paste and drop in your list: up to 20 long URLs, one per line. Copy them straight from a spreadsheet column — no reformatting needed.
• Optional: set custom endings for the batch, or protect the whole batch with one shared password. If every link in the list needs a gate, that pairs naturally with batch password protection: how to password-protect a link works the same way on bulk links.
• Click shorten. You get back 20 short links in the same order, ready to copy as a list back into your spreadsheet.

Running 20 at a time, you can work through 100 links in five pastes — about two minutes, versus the better part of an hour by hand. The honest gate: bulk paste needs Urlzbit Pro at $9 per 30 days. On the free plan you shorten one link at a time, which is fine for the occasional three or four links — see exactly what Pro unlocks: Urlzbit pricing for the full feature list.

Method 2: CSV import — up to 100 rows per file

When your list passes fifty links, stop pasting and start importing. A CSV is a plain spreadsheet saved in comma-separated format, and it is the standard way batch tools move link lists around. It beats paste for three reasons: it scales, it lets you set a custom ending per link, and the file itself becomes your record of what you shortened and when.

Preparing the file

Open any spreadsheet app. Column A holds the long URL; Column B is optional and holds the custom ending you want for each link — the part after the slash. One link per row.

• https://yourstore.com/products/blue-widget, blue-widget-launch
• https://yourstore.com/products/red-widget, red-widget-launch
• https://yourstore.com/products/green-widget, green-widget-launch

Save the sheet as CSV. You can include a header row naming the columns (destination, slug) — most import tools read it fine, and if the preview looks wrong, just delete the header row and re-upload.

Importing on Urlzbit

• Open bulk import in your Urlzbit dashboard and upload the file.
• Check the preview row: this is your last chance to spot a malformed URL before it becomes a broken short link.
• Confirm the import. You get back a results file with every long URL matched to its new short link — save it, because that file is your batch's paper trail.

Two limits to know: CSV import is a Pro feature ($9 per 30 days), and each file takes up to 100 rows. A 500-link catalog splits across five files — still a few minutes of work, not an afternoon.

Method 3: API bulk creation

The API is the method for jobs that never stop: a nightly product-feed import, links your own app generates, or an automation that shortens every URL your team drops in a channel. Instead of pasting, your code sends each URL to the shortener and stores the short link it gets back.

The honesty section, because this is where shorteners quietly differ: on Urlzbit, the Developer API is a paid feature — Pro ($9 per 30 days) or Business ($29 per 30 days, with 50,000 links). There is no free API on Urlzbit, and anyone describing one is describing a different tool. That is worth knowing before you build: Short.io includes API access on its free plan (within its 1,000 link-automation quota), and Bitly's free plan caps API calls at 1,000 per month. If your pipeline needs thousands of API-created links a month, price the API tier, not the headline plan. Developers: the URLZBit API tutorial walks through authentication, link creation, and rate limits with cURL, Python, and JavaScript examples.

Bulk limits compared: Bitly vs Cuttly vs Short.io vs Urlzbit

This is the comparison no ranking page currently makes with current prices, so here it is — what bulk shortening actually costs and caps at on each major tool. Prices checked October 2026.

• Urlzbit — bulk from Pro at $9 per 30 days: paste up to 20 URLs per batch, CSV import up to 100 rows per file, unlimited clicks on the shortened links. No auto-renewal — you pay per 30-day block. The free plan shortens one link at a time (100 saved links, 10,000 clicks a month) but has no bulk. Full plan details: Urlzbit pricing lists every feature per tier.
• Bitly — bulk from Growth at $29/month billed annually ($35 month-to-month): up to 100 links per upload; Premium ($199/month billed annually) raises the cap to 3,000 per upload. Free and Core have no bulk creation at all. Plans renew automatically. If you are weighing the two brands' free tiers first, read the free-plan comparison: Bitly alternative for why Bitly's 5-links-a-month free plan runs out in a week.
• Cuttly — CSV bulk from Single at $25/month: 100 links per month via CSV; Team ($99/month) raises CSV to 2,000 per month. The free plan (30 links a month) has no CSV bulk and no password links.
• Short.io — the outlier: even the free plan includes link automation (API or bulk create) for 1,000 links lifetime, with 50,000 tracked clicks a month. The trade-off: Short.io is built around branded domains — its bulk path assumes you have connected a domain first, and its paid tiers climb from there. If you already own a domain and want maximum free automation volume, Short.io's free tier wins on raw numbers. If you want the cheapest simple CSV path with no domain setup and no auto-renewal, that is Urlzbit Pro at $9 per 30 days.

The takeaway: bulk is a paid-tier feature almost everywhere, and the cheapest entry point varies by what you value — free volume (Short.io), or the lowest-priced simple CSV workflow (Urlzbit Pro).

Mistakes that waste a batch

Bulk makes mistakes bulk-sized. Run through this checklist before every batch and you will rarely re-run one.

• Add UTMs before shortening, not after. A batch bakes the destination URL in. If you forgot ?utm_source on 200 product URLs, you are not editing one link — you are re-running the entire batch. Tag the long URLs first, shorten second. The UTM parameters guide shows the naming and builder workflow.
• Test a small sample first. Shorten three to five links, click every one, and confirm the destinations load and the clicks register in your analytics. Only then run the full file. Five minutes of testing beats an hour of re-work.
• Mind expiry and scheduling. Links with expiry or schedule dates behave the same in bulk as singly — a batch of expired links is a batch of dead links. If your tool supports scheduling per link, set the dates during the import, not after.
• Deduplicate your list. Spreadsheets hide duplicates; the same long URL shortened twice creates two short links that split your click data across both. A quick sort-and-dedupe in the spreadsheet takes thirty seconds.
• Keep the batch in one tool. Analytics are per short link. If half your campaign lives in one shortener and half in another, you will never get a clean total. Pick the tool before the batch, not during it.

FAQ

Can I shorten multiple URLs at once for free?

Yes, with limits. Short.io's free plan automates up to 1,000 links (through its branded-domain setup). On Urlzbit, bulk paste and CSV import are Pro features at $9 per 30 days; the free plan shortens links one at a time, up to 100 saved links. Bitly and Cuttly gate bulk behind paid tiers entirely.

How many URLs can I paste at once on Urlzbit?

Up to 20 per paste on the Pro plan, with no limit on how many pastes you run back to back. For bigger jobs, CSV import takes up to 100 rows per file.

Does bulk shortening cost extra on Bitly?

Bulk is not an add-on — it is a tier gate. Bitly's bulk creation starts on the Growth plan ($29/month billed annually, $35 month-to-month) at 100 links per upload, and rises to 3,000 per upload on Premium. Free and Core plans cannot bulk-shorten at all.

Can I use a CSV on Cuttly's free plan?

No. CSV bulk import on Cuttly starts at the Single plan ($25/month) with 100 links per month via CSV. The free plan covers 30 links a month, shortened individually.

Is there a limit on clicks for bulk-shortened links on Urlzbit?

No. Pro includes unlimited clicks, and the free plan allows 10,000 clicks per calendar month across your links. The click limits that matter in this niche are on the free tiers elsewhere — Bitly's free plan, for example, is 5 links a month before you hit the wall.

Shortening in bulk is one of those tasks that feels like it should already be solved — and it is, as long as you pick the method that matches your list size and a tool whose bulk tier you can actually afford. For a one-off list under twenty links, paste does it in a minute. For a few hundred, a CSV is the professional move. For a pipeline, price the API tier honestly.

If you want to try it, start with the free shortener: urlzbit.pro — and when your lists outgrow one-at-a-time, Pro's bulk paste and CSV import are $9 per 30 days with no auto-renewal. See Urlzbit pricing
