Caption text on images, not pin-style annotations

Text Overlay adds caption text blocks on a client-side canvas — not arrows, pins, or numbered callouts. You type your caption, drag it into place, and tune font, size, color, alignment, and optional shadow or background box for contrast. For screenshot callouts with pins and labels, use Pix-8 Image Annotator instead. It does not include pins, arrows, or multi-annotation layers.

Why add captions to images online in the browser?

Caption tools that rely on cloud processing upload your file before you describe what's in the frame. Pix-8 keeps captions local — the direct fit when you need to add captions to images online with on-device positioning and export that never routes pixels through a remote server.

Client-side captioning

Your image is read and composited locally in your browser tab while you add captions. Pix-8 does not receive your pixel data.

Caption layout you control

Type captions, drag them into place, and adjust font, color, and left/center/right alignment on a client-side canvas so they stay legible over the image.

Flattened local export

Download or copy one image with captions baked in, with optional EXIF stripping before you share or archive.

Frequently asked questions

Can I add captions to images online without uploading them?

Yes. Pix-8 Text Overlay runs entirely in your browser. Your image is read locally, caption text is rendered on a client-side canvas, and you export from your device. It is never transmitted to Pix-8 or any third-party server.

Is this for captions or full image annotations with pins?

This landing focuses on typed captions — one or more lines of text you place on the image with font, size, color, alignment, and optional shadow or background box controls. For pin-style callouts, arrows, or numbered markers on screenshots, use Pix-8 Image Annotator instead. Text Overlay does not include pins, arrows, or multi-layer annotation workflows.

What kind of caption styling does this tool support?

You can drag captions into position, choose font family and size, set color, align left/center/right, and toggle optional shadow and background box opacity. Then download or copy the flattened output, with optional EXIF stripping before export. It does not include curved text, outline strokes, or rich multi-line text layouts.
