Your cleaned combo base will appear here.
Paste a list or import a TXT file, then adjust the local cleaning rules.
Only clean combo lists and account data that you own or are explicitly authorized to handle. This utility transforms local text and never validates credentials against a service.
Remove repeated combo lines with transparent matching
The deduplicator normalizes identifiers without changing password capitalization, retains the first matching line and reports every removed duplicate.
Combo optimiser
Normalize whitespace and email casing while preserving the password exactly as entered.
Duplicate remover
Remove repeated combo lines and see how many duplicates were detected in the source base.
Capture remover
Strip pipe- or tab-separated capture data after a combo while keeping the identifier and password.
Password filters
Filter by minimum or maximum length and require uppercase, lowercase, number or symbol characters.
Email combo filter
Keep only valid email:password lines when a workflow requires an email-formatted identifier.
Copy and TXT export
Copy or download the cleaned combolist and review rejected lines with their removal reason.
A combo cleaner that never receives your base
No account, server upload or credential check—only local text processing inside the current browser tab.
100%
Local processing

03How to remove duplicates from a combo list
Use deterministic identifier and password matching to reduce repeated entries without contacting an account or authentication service.
Paste or import an authorized list
Add username:password or email:password lines, or load a local TXT file. Capture removal starts disabled on this focused page.
test.user@example.com:DemoPass123!Keep duplicate removal enabled
Email identifiers are normalized without case differences while each password remains case-sensitive.
Review the duplicate counter
The first normalized match stays in the clean output. Repeated matches appear in the removed-lines report with the duplicate reason.
Export the unique combo base
Copy the result or download clean and removed reports as local TXT files.
Deduplication features
Know exactly what counts as a duplicate
Duplicate removal is based on a normalized identifier plus the exact password. This catches email casing differences while preserving passwords whose capitalization may be meaningful.
The tool performs no credential validation and makes no network requests. Use it only for internal QA, defensive exposure response or another workflow where the dataset is yours to process.
- Retain the first matching normalized line
- Preserve password capitalization exactly
- Review every rejection before export
