How it works
For 1000 heart emojis to copy and paste, press the button: the page opens with 1,000 red hearts already built. Paste any other emoji over the heart and it is repeated the same way, up to 10,000 times.

Your own emoji and count
The box under Your text holds one red heart. Type or paste another emoji over it and the run changes to that. The number in Repeated 1,000 times takes 1 to 10,000, and 10, 100, 1,000 and 10,000 set it in one tap.
What a red heart is made of
A red heart is two characters: ❤ Heavy black heart, U+2764, then the invisible Variation selector-16, U+FE0F, which asks for the emoji drawing. So 1,000 red hearts are 2,000 code points and 2,000 UTF-16 units, and 6,000 bytes as UTF-8. The page shows the first 500, and the button copies all 1,000.
- 1000 laughing emoji to copy and paste: put 😂 Face with tears of joy in the box. For 1000 crying emoji, 😭 Loudly crying face.
- A blue heart 💙 is one code point, not two, yet 1,000 of them are still 2,000 UTF-16 units, and 4,000 bytes.
- Under More options, set New line after every so many copies to 25 and 1,000 hearts arrive as 40 rows of 25.
Questions and answers
How do I get 10000 emojis to copy and paste?
Press 10,000, then the copy button. For red hearts that run is 20,000 code points and 60,000 bytes as UTF-8, and the page still shows only the first 500 hearts of it.
Why do my red hearts arrive as small black hearts?
The second character was lost. Without Variation selector-16 the heart is a bare U+2764, Heavy black heart, which Unicode gives a text drawing by default. An app that drops the selector, or draws from a text font, shows the black shape.
Can I repeat an emoji that is not a heart?
Yes. Whatever is in the box is what gets repeated: one emoji, several in a row as a pattern, or plain words. A one-code-point emoji such as 😂 takes two UTF-16 units, so 1,000 of them still measure 2,000.
How many hearts can it copy at once?
Up to 10,000 in one run. The tool also stops any run at one million UTF-16 units, a ceiling that 10,000 red hearts, at 20,000 units, come nowhere near.
