Speech Bubble Maker (Free — Add Comic-Style Speech Bubbles to Photos)

A free tool to add a speech bubble to a photo or image, comic-book style. Choose from rounded, oval, or thought-bubble shapes, then freely adjust position and size and type in your text. Everything runs in your browser, so nothing is ever uploaded to a server.

What Is the Speech Bubble Maker?

The Speech Bubble Maker lets you add a classic comic-style speech bubble on top of any photo, complete with your own line of dialogue or inner monologue. Pick from three shapes: a familiar rounded-rectangle bubble, a softer oval, and a thought bubble whose tail is drawn as a trail of small circles instead of a pointed triangle.

Everything, from uploading the image to positioning and resizing the bubble, typing the text, and exporting the finished picture as a PNG, happens right in your browser using JavaScript's Canvas API. Your image and the text you type are never sent anywhere, so it's a safe way to annotate a screenshot or add a caption to a personal photo.

Tips for getting more out of it

Point the tail toward the corner closest to the speaker's mouth for a more natural-looking result.
Add several bubbles at once to build a conversation-style collage from a single photo.
The "thought" shape reads more clearly when it's used for something a character is thinking rather than actually saying out loud.
Long lines wrap onto multiple lines automatically, so there's no need to add line breaks yourself.
If you want to add big, bold caption text on top of the finished image, you can also use the meme generator.

Speech Bubble Terms

Side Note — When Did the Speech Bubble Become a Comic Staple?

Enclosing a character's words in a shape turns out to be a much older idea than modern comics. Medieval European paintings and prints sometimes show a "speech scroll," a ribbon-like banner unfurling from a figure's mouth with Latin text written on it, which historians consider a distant ancestor of today's speech bubble.

The bubble as we know it today, an outlined shape with a tail pointing to the speaker, is generally traced back to the American newspaper comic strips of the late 19th and early 20th centuries. As printing technology matured alongside mass-circulation newspapers, the speech bubble became a convenient, space-efficient way to fit dialogue directly into the artwork.

The thought bubble's distinctive trail of small circles, rather than a pointed tail, was also a device cartoonists of that era invented to visually separate "words spoken aloud" from "thoughts inside someone's head." That simple trick, conveying two very different, invisible things through the shape of a line alone, is still used in comics all over the world today.
