Add Text to Image

Captions, prices, dates, names, quotes or a quick label on a screenshot — adding text to a picture should not need a design app. This tool writes one or several lines onto your images with the font, size, colour, outline, shadow and background box you choose, in any of nine positions with optional rotation. The same text can be stamped on a whole batch, and the images never leave your browser.

How to use this tool

1. Choose one or more images and type your text (Enter starts a new line).
2. Pick a font and size. The size is a percentage of the image width, so it looks the same on large and small pictures.
3. Choose a text colour and an outline for contrast, or a semi-transparent background box for text over busy photos.
4. Place it with one of nine positions, fine-tune with the move and rotation fields, then save as the original format, JPG, PNG or WebP.

Formula

Text size (px) = size % × image width ÷ 100; margin = 4% of the shorter side

The text block (plus box padding of 0.3 × text size) is placed inside the margins by its anchor: left = margin + (W − 2·margin − block width) × a, where a is 0, 0.5 or 1 for left, centre and right, and likewise for the top. The move fields shift it by a percentage of the width and height; rotation turns it around its own centre. The outline is drawn first with rounded joins, so the letters themselves keep their full shape.

Example

On a 1080 × 1080 px photo, a size of 8% gives text 86 px tall (8 × 1080 ÷ 100 = 86.4). With bottom-centre placement the margin is 43 px, so the baseline area sits just above the bottom edge — a typical caption. An 8% outline adds a 7 px black edge that keeps white letters readable on bright skies.
