😂 Meme Generator

What is the Meme Generator?

A meme in the everyday sense is an image with a short, punchy caption laid over it, usually one line across the top and one across the bottom. The look that became standard online uses the Impact typeface (a heavy, condensed sans-serif), set in white capitals with a solid black outline so the words stay readable over any background, light or dark. This tool reproduces that style: it draws your photo to an HTML canvas, then strokes each line in black and fills it in white on top, the same layering that gives the lettering its signature outlined edge.

The text is sized as a percentage of the image height rather than a fixed point size, so the caption looks right whether your picture is a small thumbnail or a large photo. Each line is also measured against the image width and wrapped onto extra lines if it is too long, which stops a wordy caption from running off the edge. You control the relative size with a slider, choose uppercase (the classic look) or as-typed casing, and the top block grows downward from the top edge while the bottom block grows upward from the bottom edge.

Because everything happens locally with the FileReader and canvas APIs, your image never leaves the browser, which matters when you are memeing a private photo or a screenshot. The download is generated with canvas.toBlob, so the file you save is exactly what you see in the preview at full original resolution. Export as PNG for a lossless result on graphics and screenshots, or JPEG and WebP (with an adjustable quality) for smaller files on photographic images.

When to use it

• Turning a reaction photo or screenshot into a shareable meme with top and bottom captions.
• Adding a bold, readable headline or label to an image for social media without opening an editor.
• Captioning a private or sensitive photo locally, so the picture never gets uploaded anywhere.
• Quickly mocking up a meme idea to see how the wording fits before posting it.

How to use the Meme Generator

1. Choose an image from your device using the file picker.
2. Type your top text and bottom text in the two fields.
3. Adjust the font size slider and pick uppercase or as-typed casing if you want.
4. Pick an output format (PNG, JPEG or WebP) and, for JPEG or WebP, a quality.
5. Check the live preview, then click Download meme to save the finished image.

When to use each output format

Common mistakes to avoid

• Typing very long captions and expecting one line. A long sentence is wrapped onto several lines so it fits the width. If you want a single line, shorten the wording or lower the font size slider so more text fits across.
• Exporting JPEG and wondering where the transparency went. JPEG has no transparency, so any transparent areas of a PNG source are filled with white on export. Choose PNG or WebP if you need to keep transparent regions.
• Assuming the preview is downscaled. The preview may be shrunk to fit the page, but the download is rendered at the image's full original resolution, so the saved file is sharper than the on-screen preview suggests.
• Worrying the photo is uploaded somewhere. It is not. The file is read with the browser FileReader and drawn to a canvas on your own device. No image or text is sent over the network.
