Local text tools in the browser: counter, Base64, JSON and UUID

You copy a production log fragment, an email list from a spreadsheet or a JSON API response. Before it goes into a ticket, you may need to count length, remove duplicates, decode Base64 or generate a test UUID. These small operations are exactly what people often paste into random online forms.

txtify.ru is a set of short local text operations. Open the tool, paste the text, get the result, and skip the account. The important part is not the word "free"; it is that the available operations run in the browser.

Counting and cleaning text

The character counter is useful beyond SEO titles and meta descriptions. It helps check field limits, UI copy length, UTF-8 byte size and rough text volume before publishing. For limits and UTF-8 details, use the focused guide on how to count characters in text.

Duplicate line removal handles another common workflow: clean a list of emails, SKUs, keys, URLs or table rows. Instead of manually searching for repeated values, paste the list, choose the mode and copy the clean result. If order and empty lines matter, read the separate guide on how to remove duplicate lines.

JSON, Base64 and UUID

JSON formatter is useful for logs, API responses and config files. It surfaces parse errors and turns dense JSON into something readable. Local processing matters here because JSON often contains tokens, emails, user IDs and internal fields. A formatter does not validate your business schema or make secrets safe; it only checks syntax and indentation.

Base64 helps inspect an encoded string or prepare a URL-safe variant with the padding you need. Important caveat: Base64 is not encryption; it is byte-to-text encoding. For details, use the guide on decoding Base64 locally.

UUID generator covers one-off testing tasks: create several UUIDs of the needed version and paste them into fixtures, migrations or manual requests. UUID v4 is useful for random test IDs, v7 is easier to sort by time, but no UUID should be treated as a secret or password.

Why not a cloud notepad

After transforming text, check the result in context: JSON can be valid but not match an API schema; Base64 can decode into binary data; a UUID can be valid but the wrong version. A local tool helps avoid unnecessary upload, but it does not replace domain checks.
