How to add text to an image

A few words on a photo can turn it into a greeting card, a meme, a quote card, or a product label. Adding text is one of the simplest edits you can make: type the words, pick a size and a color, choose where the text sits, and download the result. The steps below do it in your browser on ImageTool.us, with no upload and no signup.

1. Step 1: pick a photo and keep the original

Start with the photo you want to write on — any common format works (JPG, PNG, or WebP). Keep a clean copy of the original before you begin: the text is baked into the downloaded copy, so the only way to change the words later is to start over from the original. The original on your device is never changed; the tool only makes a new copy with your text for you to download.

2. Step 2: open the tool and upload your photo

Open the Add Text to Image tool and upload your photo — click to choose it, or drag and drop it onto the page. The original appears in the preview on the left. Nothing is uploaded: the file stays on your device and the work happens in your browser.

3. Step 3: type your text and set the size, color, and position

Type your words in the text box — up to 120 characters. Then set the font size with the slider, from 16 to 200 pixels (the default is 64), pick a text color with the color picker (white is the default), and choose a position: top, center, or bottom. The text is always centered across the width of the photo. Try a large size for a poster or a greeting card, and a small size for a caption or a label. If the photo is busy, white text works best: the tool adds a soft dark shadow behind the letters automatically, which keeps them readable even over bright or detailed areas.

4. Step 4: click Add Text and save the result

Click Add Text. The result appears next to your original so you can compare them before saving — check the spelling and the size while you still can, because the text cannot be edited after you download. When you are happy with it, tap Download below the result to save the new copy — it is called text-image.png. The result is always saved as a PNG, which keeps the letters crisp, and transparent areas in your image stay transparent.

What adding text is good for

Text on a photo works for social media captions, quotes, names on greeting cards, labels on product photos, and watermarks made of plain words — a name, a website, or a short credit line across the bottom of a photo. Because the text is drawn on the image itself, it shows up everywhere the photo is shared, with no special app needed to see it. It also works for birthday and announcement images: a photo plus a few words is a card in seconds, and a short quote over a landscape makes a shareable post for any feed. The key is that the words are part of the picture, not attached to it — they travel with the file wherever it goes.

How to make text readable on a photo

The first rule is contrast: the text color should stand out from the photo behind it. White text over a dark area and black text over a light area are the two combinations that almost always work, and the tool's automatic dark shadow helps white text stay readable even over bright or busy parts of the photo. The second rule is placement: put the text on a plain area of the photo — a sky, a wall, a shadow, or any stretch with little detail — instead of over a face or a busy pattern. The third rule is length: a few words read better than a paragraph, so keep it short and let the photo do the talking. A long sentence in a large font can also overflow a small image, so shorten the text or pick a smaller font size if the words run off the edges.

Text, watermarks, and memes — how they differ

Adding text, adding a watermark, and making a meme all put words on a photo, but they serve different goals. Plain text is a caption or a message: short, readable, and meant to be read. A watermark is a claim of ownership — a name or a logo placed in a corner so the photo cannot be reused without credit, usually small and unobtrusive. A meme is a joke: bold text at the top and bottom of an image, sized for quick reading and sharing. The Add Text to Image tool can do all three in a basic way, but if you want the classic meme layout, the Meme Generator is built for it, and if you want a repeated watermark across many photos, the Add Watermark tool does that faster. Use this tool when the words are the message itself.

Combine text with other edits

Text pairs well with the other tools on ImageTool.us. If the photo needs a quick fix first, the Image Editor handles cropping and rotating before you add the words — a tighter crop often leaves a cleaner space for the text. If the photo needs to be a specific size for a post, resize it with the Image Resizer first, then add the text at a size that fits the final dimensions. And if the file is too large to share afterward, run the result through the Image Compressor — just remember that converting the PNG to JPG also removes transparency, so compress it only after you are happy with the text.

Honest limits

• The text is flat, drawn on top of the photo. It does not bend around objects, follow a curve, or sit behind a person in the picture — it is a straight line of letters across the image, centered horizontally.
• There is one font: a clean, bold system sans-serif (Arial / Helvetica). There is no font choice, no italic, and no outline option beyond the automatic dark shadow that helps readability.
• The tool does not pick a color from the photo automatically. You choose the text color yourself, so if the color clashes with the photo, the text can be hard to read — check the preview before downloading.
• Text cannot be edited after the image is downloaded. The words are baked into the copy, so check the spelling, the size, and the position in the preview first, and keep your original if you may want different words later.
• Very long text may overflow small images. The text box accepts up to 120 characters, but a long line in a large font can run off the edges of a small photo — shorten the text or pick a smaller font size.

Common mistakes

• Writing a paragraph instead of a few words — a long block of text is hard to read on a photo and often overflows the image. Keep it short.
• Choosing a color that matches the photo — light text on a light sky or dark text on a dark background disappears. Pick a high-contrast color, and use the white default when in doubt.
• Placing text over a face or a busy pattern — the letters get lost in the detail. Put the text on a plain area of the photo instead.
• Downloading without checking the spelling — the text is baked into the copy, so a typo means starting over from the original.
• Forgetting to keep the original — if you want different words later, you need the clean photo. Keep it before you add the text.

Quick checklist

• Original clean copy kept before adding text.
• Text typed: short, spelled correctly, and checked in the preview.
• Font size picked: large for posters and cards, small for captions and labels.
• Color and position chosen: high contrast with the photo, placed on a plain area.
• Downloaded as text-image.png (PNG, so the letters stay crisp).
• File too large to share? Compress the result afterward, or convert it to JPG.
