This page converts a JPG (or JPEG — the same format with two spellings) into an SVG. A JPG is a grid of pixels compressed so photos stay small. SVG stores shapes as coordinates and curves. A JPG to SVG conversion therefore has to redraw every edge, not rename the file.
Wrapping the JPG inside an SVG with an image tag keeps the pixels. Enlarge that file and the stairs come back. This tool runs an AI tracer on the uploaded JPG, fits smooth curves to the colour areas, and writes a standard SVG of filled paths.
JPG has no transparency. A white box around a logo becomes a shape unless you drop it on the result page. The box also accepts PNG and WebP, but a file that already has a clear background is better on the PNG to SVG page. The watermarked preview is free; a clean download costs 10 credits.
