About this tool

Prepare images for social posts and other fixed-size layouts without installing an editor. BorderLab combines border width, background style, crop position, aspect-ratio presets, zoom, outlines, and batch export in one live preview. Your source image remains visible while settings change, making it easier to compare framing before downloading the finished file.

How to use it

Upload one image or a batch, or load the sample image.

Choose an output preset and adjust the border, background, crop, and image position.

Check the preview, choose PNG or JPG, and export the finished image or batch.

Good to know: Keep the browser tab open until a large batch finishes exporting.
