About adding text to images
Adding text to an image lets you turn a photo into a quote graphic, a labelled diagram, a social post, a watermark or a simple caption. The key to readable text is contrast: a light colour with a dark outline (or vice-versa) stays legible over almost any background.
This tool centres your text at the top, middle or bottom, wraps long captions automatically, and lets you set the size and colour. Everything is rendered in your browser, so your image is never uploaded.
Size the text for where the image will be seen, not for your editing screen. A caption that reads comfortably at full size can vanish when a social feed shrinks the image to a thumbnail a few hundred pixels wide. A rough rule: if you view the result scaled down to phone size and can still read it, you are safe. Short punchy lines survive shrinking far better than full sentences.
Mind the edges. Many platforms crop images to fit — a wide photo becomes a square in a grid, stories lay interface buttons over the top and bottom of the frame, and video thumbnails get timestamps in a corner. Text placed hard against an edge is the first thing lost. When a platform decorates the top and bottom, the middle position is the safe choice — and it is worth checking the posted result once before sharing widely.
Frequently asked questions
How do I add text to an image?
Upload your image, type your text, then set the position (top, middle or bottom), size and colour. Turn on the outline for legibility over busy backgrounds, and download.
Will the text be readable over any background?
Yes — keep the outline on and the text gets a dark edge that keeps it legible over light, dark or busy areas. You can also change the text colour to suit.
Can I add a long caption?
Yes. Long text wraps automatically to fit the image width, across as many lines as needed.
Is my image uploaded?
No. The text is drawn entirely in your browser, so your photo never leaves your device.
Will the text stay sharp if I resize the image later?
The caption is drawn into the image's pixels, so it scales with the photo. Shrinking is safe — text stays crisp. Enlarging softens it along with everything else, because there is no vector layer to re-render. So do any upscaling first and add the caption as the final step, at the dimensions you actually intend to publish.
