Quick answer: to make a meme, open a meme generator such as Altto’s free Meme Generator, upload a JPG, PNG or WebP image, type a top and/or bottom caption, and click Download meme (PNG).
The preview updates as you type, there’s no watermark or sign-up, and your image is captioned on your own device rather than uploaded.
Almost every meme, however different the images look, is built from the same two ingredients: a picture that sets up a situation, and short text that reframes or reacts to it. You don’t need design software or an app — a browser tab and a picture is all it takes.
How to make a meme in your browser
- Open Altto’s Meme Generator and click or drag in the image you want to caption — a photo, a screenshot, a reaction still. It accepts JPG, PNG and WebP.
- Type your top line and/or bottom line into the two caption boxes. The preview updates live as you type. Leave either box empty if you only want one caption.
- Use the Text size slider to make the captions bigger or smaller until they sit comfortably on the image.
- Click Download meme (PNG). You get a PNG with the captions baked in — no watermark, no sign-up.
A few things the generator does for you: captions are set in capitals automatically, in white Impact with a black outline, and long captions wrap onto extra lines rather than running off the edge. Everything happens inside the browser tab: your image is drawn and captioned on your own device and never sent to a server, so there’s nothing uploaded and nothing kept.
How to make a meme on your phone
Because it’s a web page rather than an app, you can open the Meme Generator in your phone’s browser and pick a photo from your camera roll the same way — there’s nothing to install.
Your phone’s own photo editor can also add text. On an iPhone, open the photo in Photos, tap Edit, then the Markup tool, and add a text box. On Android, Google Photos has a similar Markup option with a text tool. (Menu names vary a little between versions.) These are fine for a quick label, but they don’t give you the classic outlined meme lettering, and positioning text neatly with a finger can be fiddly.
Dedicated meme apps and websites are the other option. Many are free, but some add a watermark to free downloads, ask you to sign up, or upload your photo to their servers to process it — worth checking before you use a personal photo.
Why memes look the way they do
The white-text-with-black-outline look comes from the early days of internet “image macros”, where Impact became the default meme font. It came pre-installed on Windows computers, it’s heavy enough to stay readable over busy pictures, and the thick outline keeps white text legible on both dark and light parts of an image. It’s now such strong visual shorthand that people recognise a meme from the font alone.
The classic layout splits the text in two: a line across the top sets up the situation, and a line across the bottom delivers the reaction, punchline or twist. Plenty of modern memes use only one — a single bottom caption reacting to an image that speaks for itself is just as valid.
Classic meme formats, and how the text splits
| Format | Top caption | Bottom caption |
|---|---|---|
| Setup / punchline | States the situation plainly | Delivers the unexpected twist or reaction |
| Expectation vs. reality | “What I thought it would be like” | “What it’s actually like” |
| Before / after | The starting state | The (often exaggerated) end state |
| Single reaction caption | Left empty | A one-line reaction to the image itself |
None of these are rules — they’re patterns worth trying first if you’re staring at a blank caption box. The image usually suggests which one fits.
Tips for meme text that lands
- Keep it short. Impact is a wide, heavy font, so a long caption wraps onto several lines and starts covering the picture. Aim for one punchy line per caption, not a paragraph.
- Put the setup on top and the punchline at the bottom. People read top to bottom, so the joke lands hardest when the twist comes last.
- Match the caption to the expression, not just the topic. The strongest memes use the picture’s existing mood — a raised eyebrow, a blank stare, a triumphant fist pump — and let the text lean into it.
- Leave room around faces. Captions sit at the very top and bottom edges, so check the preview to make sure they aren’t covering the part of the image that matters.
Choosing and preparing the image
Pick a picture where the main subject sits in the middle with some space above and below it — that’s where the captions go. If it’s cluttered or off-centre, crop it first with the free Image Cropper. Very large photos are scaled down to 1,000 pixels wide in the download, which keeps the file small but is still plenty sharp for social media and group chats. If you want to cut a person or object out of its background first, see how to remove the background from a photo.
The Meme Generator makes still images. For an animated meme, you can turn a set of images into a GIF with the GIF Maker instead.
Can you use someone else’s photo in a meme?
Altto never sees or checks the images you use, which also means the responsibility for having the right to use them sits with you, as with any image editor. Your own photos and screenshots are no issue. A copyrighted photo, film still or someone else’s artwork is worth a moment’s thought before you post it publicly. UK copyright law does have an exception for caricature, parody and pastiche, but it only covers but it’s limited to fair use of the original, so it isn’t a blanket permissionldquo;fair dealingbut it’s limited to fair use of the original, so it isn’t a blanket permissionrdquo; with the original, so it isnbut it’s limited to fair use of the original, so it isn’t a blanket permissionrsquo;t a blanket permission — and it matters most if you’re using a meme commercially, for example in marketing.
