Text reversal is the process of flipping a string of characters so that it reads in the opposite direction, either entirely, by word, or by alphabetic character only. The output has the same character count as the input in the first two modes, and the same non-letter positions in the third. The transformation is deterministic and reversible: applying the same operation twice returns the original string in full and word modes.
The concept has a longer history than the digital tools that made it common. Mirror writing, in which characters are drawn reversed so the text reads correctly only when held to a mirror, appears in Leonardo da Vinci’s notebooks from the late 15th century. The practice continued through cipher traditions, puzzle design, and early computer science, where reversed strings became a standard test case for string manipulation functions. The Oxford English Dictionary traces the term “palindrome” to 17th-century English, borrowed from Greek roots meaning “running back again.”
You reverse text by choosing one of three flip modes, pasting your input, and adjusting the character and case filters until the output matches what you need. The live preview updates with every keystroke, so you can compare options without clicking a button.
Pick a mode: Full Reverse, Reverse Words, or Reverse Letters Only. The default is Full Reverse.
Paste or type your text into the input textarea. The default is “Hello World! This is a test.”
Adjust character handling if you want to strip numbers and symbols from the output.
Adjust case handling if you want to convert to lower, upper, or inverted case.
Pick special options if you want to trim whitespace or collapse multiple spaces before reversing.
Change the word separator if you’re working with commas, pipes, or other delimiters in Reverse Words mode.
Read the live preview at the top of the results section to see the reversed output in real time.
Use the buttons below to Reverse, Copy, Swap input and output, Clear, or Download the result as a text file.
Take the classic pangram “The quick brown fox jumps over the lazy dog.” Here’s how each mode handles it.
Full Reverse. Every character flips. The output is “.god yzal eht revo spmuj xof nworb kciuq ehT”. Spaces become positions in the reversed string, so words appear jumbled rather than mirrored in order.
Reverse Words. The tokens flip, but the letters within each token stay in place. The output is “dog. lazy the over jumps fox brown quick The”. The sentence is now ungrammatical but each word is intact. This is useful for word puzzles and for reversing lists separated by commas.
Reverse Letters Only. Only the alphabetic characters reverse. The period at the end stays at the end. The output becomes “ehT kciuq nworb xof spmuj revo eht yzal god.” — which is the same output you’d get from reversing letters in place, with the period anchored at its original position.
The word count is 9 for all three modes because the separator count is unchanged. Character count is 44 for all three modes. Line count is 1. The reverse length equals the input length in Full Reverse and Reverse Words modes; it can be shorter in letter-only mode if you also enable character filtering.
If you set the case handling to “Invert” on the Full Reverse result, the capital T in “The” becomes lowercase and the rest of the letters flip their case, producing “.GOD YZAL EHT REVO SPMUJ XOF NWORB KCIUQ eht” the inversion is applied after the reversal.
Type or paste your text into the input field, pick a mode (Full Reverse, Reverse Words, or Reverse Letters Only), and the output updates in real time. Use the Copy button to grab the result.
A palindrome is a word or phrase that reads the same forwards and backwards after ignoring spaces, punctuation, and case. “Racecar” and “A man a plan a canal Panama” are classic examples. The tool has a dedicated palindrome test mode.
Switch to Reverse Words mode. The word order flips but the letters within each word stay in place. “Hello World” becomes “World Hello.”
Instagram doesn’t have a native reverse text feature, but you can use a browser-based tool like this one to generate reversed text and paste it into a caption or bio. Instagram displays the reversed string as-is.
Emoji are stored as multiple code units. Reversing them character-by-character splits the code units and reassembles them out of order, which breaks the visual glyph. This affects most browser-based reverse text tools.
Use the Palindrome Test mode. It strips everything except letters and digits, lowercases the result, and compares it to its reverse. If they match, the input is a palindrome.
“Tattarrattat” (from James Joyce’s Ulysses) is often cited as the longest single-word palindrome at 12 letters. Longest palindromic sentences are much longer but depend on how you define “sentence.”
Yes. Open this page in Safari or Chrome on iOS, paste your text, and use the mode buttons. The tool works in mobile browsers with the same functionality as desktop.
Mirror writing is text written in reverse so that it reads correctly when held to a mirror. Leonardo da Vinci used it extensively in his notebooks. Full Reverse mode produces text that can be read in a mirror when combined with the correct case handling.
Switch to Reverse Words mode, then change the word separator field from a space to a comma. The tokens between commas reverse while the commas themselves stay in place.
You get the original text back. Full reverse and reverse words are involutions, meaning applying them twice returns the input unchanged. This is useful for verifying that a reversal completed correctly.
The option is present in the dropdown but the tool’s code does not implement a distinct behavior for it. Use Reverse Letters Only mode if you want punctuation anchored in place while letters reverse.
