Inkscape builds drawings from vector objects rather than painting a fixed grid of pixels. A logo, map, diagram, or page can contain rectangles, text, curves, groups, and reusable clones. Inkscape stores the geometry and styling of those objects, so the artwork can grow or shrink without the blocky edges that appear when a small bitmap is enlarged. It changes the drawing document, not the photographs or fonts installed elsewhere on the computer. A PNG export is a pixel copy of the result; it does not replace the editable vector source.
Objects and paths
Inkscape keeps rectangles, ellipses, stars, and spirals as live shapes. Their handles control properties that belong to that shape, such as rounded rectangle corners or the number of points on a star. A path works differently. Its nodes and segments can form almost any outline, but it no longer has the original shape controls.
Converting a shape to a path makes every node available for direct editing. That conversion has no reverse command. A star converted to a path may still look like a star, but Inkscape no longer knows it as a star object, so the star handles and point-count field disappear. Keeping an untouched copy matters when later edits may need those controls.
Shape tools also remember their latest parameters. Changing a star and then drawing another can carry the altered point count or rounding into the new object. Simply selecting an existing shape with its matching tool can update those remembered values. This behavior saves repeated setup, but it can also make the next shape arrive with unexpected settings.
Groups and stacking
Every object occupies a position in the stacking order. Raising an object moves it above overlapping artwork; lowering it can hide it behind another object without deleting it. When several objects overlap at the same point, repeated Alt-click actions cycle through the stack. Some Linux desktop environments reserve that shortcut for moving windows, so the window manager may intercept it before Inkscape receives it.
A group lets several objects move and scale as one unit while preserving the objects inside. Groups can contain other groups. The ordinary Ungroup command removes only the outer level, so deeply nested artwork may need several ungroup actions. Inkscape can instead enter a group or select one member inside it, which avoids dismantling a layout merely to change one fill or line.
Duplicating an object places the new copy directly on top of the original. The duplicate can look like a single unchanged object until it moves or changes color. The stacking order and status bar help distinguish the selected copy from the source.
Clone links
A clone is linked to one original object. Changes to the original shape or style appear in every clone, while each clone can keep its own position, rotation, and scale. This suits repeated symbols whose design should stay consistent across a drawing.
Inkscape does not let the node tool reshape a clone independently. Unlink Clone converts it into a separate object, after which later edits to the original stop reaching it. Unlinking too early removes the shared relationship; leaving it linked prevents a one-off shape change.
Output copies
Inkscape recommends keeping the working document as Inkscape SVG and using Save a Copy for delivery formats. That separation preserves objects, guides, and editing information even when the recipient needs a PDF or raster image.
PDF output has different rules from the canvas. Filters such as blurs and shadows may need rasterization, which turns that region into pixels inside the PDF. Decorative text can be converted to paths to preserve its visible outlines on another computer, but the result is no longer ordinary editable or searchable text. These choices belong in an output copy rather than the only editable source.
