Editing SVG Online: Recolor and Remove Backgrounds Without Installing Software

1. What the online SVG editor can do

The first reaction to editing SVG is often to install Illustrator, but for light tasks such as recoloring, removing a background or deleting elements an online editor is more than enough. PolySVG's online SVG editor runs in the browser, is free, needs no installation or registration, and supports path-level operations: click to delete, one-click background removal, painting with the brush, erasing with a mask, recoloring, undo and redo, and finally exporting SVG or PNG. You can upload an SVG directly or bring in a conversion result with one click from the image to SVG tool. For designers it is a good way to do the final cleanup before delivery; for developers it is a quick way to adjust icon colors and sizes before they go into a page, without going back and forth to a design tool.

2. Recoloring: give an icon a new theme color

Click a color block on the canvas to select the matching path, then change the fill in the color panel. Typical scenarios: switching one icon set between light and dark themes, calibrating a vectorized logo to its brand color, and unifying palettes across assets from different sources. Compared with hunting for the fill attribute in code, clicking to recolor is far more intuitive and much less likely to damage other paths.

3. Removing backgrounds: automatic plus manual cleanup

Click "one-click background removal" and the engine detects the dominant border color and removes the background layer, turning a white-background SVG transparent in seconds. Any leftover background path can be selected with the mouse and deleted. If you still have a bitmap, use the image to transparent vector tool to convert and remove the background in one step, then finish the cleanup in the editor.

4. Brush and eraser: painting and erasing

The brush is additive: it paints missing strokes, and the strokes are vectorized into new paths automatically, blending into the original artwork — ideal for repairing broken strokes in a vectorized logo. The eraser is subtractive: it hides an area with a mask without destroying the original path data, and you can undo it if you erase too much. Both work together with undo and redo, so you can experiment freely. Brush strokes are added to the file as independent paths and can be recolored later by clicking them; the eraser's mask effect is applied at export time, so the exported SVG matches what you see on the canvas.

5. Undo, redo and export

The editor keeps a complete history of your actions: undo a mistake and redo it if you change your mind. When you are done, export SVG for the web or for further editing, or export PNG to place in documents or use as a preview image. For ways to open and view SVG files, see How to open an SVG file; the editor's direct link is /editor. When exporting a PNG, pick a resolution high enough to stay sharp in a document; for the web, export SVG to keep the vector properties.

6. Quick reference for common editing tasks

• Recolor icons for a theme: click a path and change its fill, then export one version for light and one for dark themes;
• Make a white-background asset transparent: one-click background removal, delete the leftover paths, export a transparent SVG;
• Repair broken strokes in a logo: paint along the gap with the brush so the strokes are vectorized automatically, then recolor uniformly;
• Delete unwanted elements: click each color block you do not need and delete it, and use the eraser for edge details;
• Images for documents: export a PNG when the editing is done and drop it into Word, PowerPoint or a chat window.
