The Bulk URL Shortener is designed to process large batches of URLs efficiently while maintaining reliable performance. To ensure stable operation for all users, SPRL applies certain limits on uploads, processing, file sizes, and customisation options.
Understanding these limits before starting a bulk operation helps you prepare your data correctly and avoid unnecessary upload or processing errors.
| Limit | Supported Value |
|---|---|
| Supported File Formats | CSV, XLS, XLSX |
| Maximum URLs per Upload | 10,000 URLs |
| Maximum File Size | 10 MB |
| Required Spreadsheet Columns | 3 columns |
When using the Personalised Link Generator for advanced bulk link creation, the following limits apply:
| Limit | Supported Value |
|---|---|
| Maximum Links per File | 50,000 links |
| Maximum Spreadsheet Columns | 20 columns |
| Maximum File Size | 10 MB |
If you choose to generate custom URL slugs during bulk processing, each slug must follow the supported validation rules.
| Setting | Requirement |
|---|---|
| Length | 6–30 characters |
| Allowed Characters | a-z, A-Z, 0-9, hyphen (-), underscore (_) |
If an upload exceeds one or more supported limits, SPRL will ask you to correct the issue before processing begins.
| Situation | Recommended Action |
|---|---|
| File is larger than 10 MB | Split the data into smaller files. |
| More than 10,000 URLs | Create multiple upload files. |
| Invalid file format | Save the spreadsheet as CSV, XLS, or XLSX. |
| Invalid custom slug | Update the slug to meet the supported rules. |
When processing thousands of URLs, following a structured workflow can improve efficiency.
| Requirement | Recommended Method |
|---|---|
| Quick list of URLs | Copy & Paste Multiple URLs |
| Spreadsheet of URLs | Excel or CSV Upload |
| Extract links from an existing webpage | Extract & Shorten URLs from a Webpage |
| Large personalised link campaigns | Personalised Link Generator |
The limits help ensure reliable processing, maintain platform performance, and provide a consistent experience when handling large batches of URLs.
By validating uploads before processing, SPRL can detect common issues early and reduce the likelihood of incomplete or failed bulk operations.
Reduce the number of rows or split the spreadsheet into multiple files until each upload is within the supported file size limit.
Divide your URLs into multiple spreadsheet files and upload each batch separately.
Verify that the slug contains only supported characters and is between 6 and 30 characters long.
Ensure the file is saved in CSV, XLS, or XLSX format, does not exceed 10 MB, and contains the required spreadsheet structure.
You can upload up to 10,000 URLs in a single spreadsheet upload.
The maximum supported upload size is 10 MB.
The Personalised Link Generator supports up to 50,000 links per file, with a maximum of 20 columns and a file size of up to 10 MB.
Split your project into multiple smaller batches and process each batch separately for the best performance.
