How it works
Upload an image, type the text you want, and adjust its position, color, opacity, and size — the tool draws it directly onto the image and downloads the combined result.
Add Watermark
Overlay custom text on an image — no sign-up, no upload, no file size limit.
Drop an image here, or click to browse
Your files never leave your device. Everything runs locally in your browser — nothing is uploaded to a server, so there's no file size limit, no subscription, and no one but you ever sees what's in your file.
Frequently asked questions
Can I add a logo/image watermark instead of text?+
Not currently — this tool adds text only. For an image watermark, you'd need a more advanced editor.
Why does my watermark barely show up on some photos?+
Light-colored text can be hard to see on a light background, and vice versa. Try switching the color between white and black, or increasing the opacity, to find what's visible against your specific photo.
Does the text size scale with the image?+
Yes — text size is set as a percentage of the image's width, so it stays proportional whether your photo is a small thumbnail or a large original.
Is my image uploaded anywhere?+
No. This tool runs entirely in your browser using JavaScript — your image is read, watermarked, and downloaded without ever being sent to a server.
Keep a backup of your original file. This tool processes everything locally in your browser, and we've tested it carefully — but no conversion tool handles every PDF perfectly. Always keep your original file and double-check important results before relying on them.
