Reverse text generator

How to use the reverse text generator

Type or paste into the box and six versions appear underneath, updating as you type. Each has a Copy button and a download button for a .txt file, and clicking inside an output selects it all, so you can paste the result straight into a message, a bio or a puzzle.

• Reversed text — every character backwards: Hello becomes olleH.
• Reversed word order — the cat sat becomes sat cat the; spelling untouched. With Keep punctuation in place (on by default) commas and full stops stay where they were, so Hello, world! becomes world, Hello! rather than world! Hello,.
• Each word reversed — word order kept, letters flipped, and punctuation left where it was, so Hello, world! becomes olleH, dlrow!.
• Reversed lines — the last line first, handy for flipping a log file or a chronological list.
• Upside down — the text rotated 180° using Unicode characters that look like upside-down letters. Tick Keep reading order to flip the letters without reversing them.
• Mirror text — flipped left to right, like writing seen in a mirror.

Keep lines in place (on by default) reverses each line separately. Untick it and multi-line text is treated as one block, so the last line comes first as well.

Why emoji and accents don’t break here

Most reverse-text tools reverse the raw code units of a string, which works for plain English and mangles almost everything else. An emoji with a skin tone is two code points; a family emoji is several people glued together with invisible zero-width joiners; a flag is two regional-indicator letters; a keycap such as 1️⃣ is a digit plus two invisible modifiers; and an accented letter may be a base letter followed by a combining accent. Reverse those naively and you get separated skin-tone swatches, broken flags (🇬🇧 turns into 🇧🇬) and accents jumping onto the wrong letter.

This tool splits text into grapheme clusters — the characters a reader actually sees — using the browser’s Intl.Segmenter, and reverses those. 👍🏽, 👩‍👩‍👧, 🇬🇧, 1️⃣ and é all survive intact. The same care applies to upside-down and mirror text: emoji and keycaps pass through unchanged, and an accented letter keeps its accent — rotated below the letter when upside down (é becomes ǝ̗), swapped from acute to grave when mirrored. Right-to-left scripts such as Arabic and Hebrew reverse correctly at the character level too, although your browser will still display them right to left.

Upside-down and mirror text: how it works

There is no “upside-down” font in Unicode. Instead, the tool swaps each letter for a different character that happens to look like it rotated — a becomes ɐ (from the phonetic alphabet), e becomes ǝ, h becomes ɥ, ! becomes ¡ — and then reverses the order so it reads correctly when you turn the screen round. Mirror text does the same with left–right look-alikes such as ɘ, ꙅ and Я.

Every letter, digit and common punctuation mark maps to its own look-alike, so both styles are exact round trips: paste upside-down or mirror text back in and the same card turns it back into the original, capitals and digits included. Because they are ordinary Unicode characters, the results paste into social media, chat apps and documents. Two caveats: a few look-alikes are missing from some fonts, and screen readers read them as unrelated symbols, so avoid them for anything people need to understand. The upside-down capitals B, D, R and T normally come from the Lisu alphabet; if your device’s fonts lack it, the tool switches to more widely supported look-alikes and tells you, and you can choose them yourself with Widely supported letters. For deliberately garbled styles, try the cursed text generator.

Checking palindromes

A palindrome reads the same forwards and backwards once you ignore spacing, punctuation and capitals: Never odd or even, Step on no pets, A man, a plan, a canal: Panama! The checker strips everything except letters and digits, folds case and removes accents (so Ésope reste ici et se repose passes), and shows you the exact string it compared.

If the whole text isn’t a palindrome, it finds the longest palindrome inside it using Manacher’s algorithm, which works in a single pass even on long texts, and highlights it in your original wording. Paste a list of candidates, one per line, and it also tells you how many lines are palindromes on their own — useful for word games and puzzle setting. Pair it with the case converter if you need the result in a particular capitalisation.
