A border adds space or a frame around a picture. Brodidit's Add text tool does not currently provide that feature.
An outer border increases canvas dimensions, while an inner frame covers image edges. A square crop removes content. These are different results and should not be described as interchangeable ways to preserve a whole photo.
Brodidit's caption controls set top and bottom wording, size, colour, outline and uppercase. A text outline is not a photo border. The tool has no frame thickness or border-colour setting and does not expand the canvas.
Collage maker offers spacing and a background for two or more photos, but its cells crop pictures square. It is useful for multi-photo layouts, not a substitute for framing a single uncropped image. Existing URLs remain available while these limitations are clarified.
There is no frame option in Text & stickers, and it is better to say so than to suggest it can do something it cannot. What the site can do is leave a gap between photos on a coloured background.
Collage maker places photos in a grid with spacing and a background colour, which gives a mat-like border around each picture when you use several photos. Merge images does the same with a row or a column. For a single photo with a plain border, an image editor is the right tool.
No. It only overlays captions.
Not necessarily. Square cells can crop the source photos.
Not at the moment. The closest options are the spacing and background colour in Collage maker and Merge images, which need at least two pictures.
