Frequently Asked Questions
What is glitch text used for?
Glitch text is popular in digital art, social media captions (for a unique aesthetic), cybersecurity testing to simulate data corruption, creating password variations, and testing spell-checker robustness.
Can I control which characters are added?
Yes, you have complete control! Toggle to include lowercase letters only, add numbers (0-9), and/or add symbols (!@#$%^&*). You can also adjust the intensity slider to control how many characters are inserted.
Will this make my text unreadable?
It depends on the intensity. At low levels (10-20%), the text remains readable but looks 'noisy'. At high levels (70-100%), it becomes complete gibberish. Use the 'Preserve First/Last Char' option to keep words recognizable even at high intensity.
What does 'Preserve First/Last Char' do?
This setting keeps the first and last letter of each word intact, only corrupting the middle letters. This maintains readability while still creating a glitch effect. Perfect for creating readable but distorted text.
Can I upload files to process?
Yes! Click the Upload button to load .txt files. Great for batch corrupting documents, creating glitch art from stories, or testing data validation systems at scale.
How can this strengthen passwords?
Turn a memorable phrase like 'bluehorse' into a strong password like 'bL7u!eHo9r$se' by using low intensity (10-20%) with numbers and symbols enabled. Creates strong passwords from easy-to-remember phrases.
Is this different from Zalgo text?
Yes. Zalgo text uses Unicode combining characters that appear above/below letters. This tool inserts actual characters within words, creating a more controlled and readable glitch effect without Unicode complexity.
Can I download the corrupted text?
Absolutely! Click the TXT button to download your glitched text as a plain text file. The filename includes a timestamp for easy organization.
How does this help with spell-checker testing?
By inserting random letters into words, you can test how robust spell-checkers and autocorrect systems handle typos. Perfect for QA testing of text input systems or search engines that need fuzzy matching.
Is my text data private?
100% yes. All processing happens locally in your browser using JavaScript. Your text never leaves your device, and nothing is sent to our servers. Completely private and secure.
