Bolt
In-browser creative suite: image compressor, SVG optimizer, palettes, audio visualizer.
Bolt is a set of small creative tools that run entirely in the browser. Optic compresses images on the user's device — nothing is uploaded — using Canvas encoding to WebP. Vector optimizes SVG markup and shows the result as both a rendered preview and code. Palette extracts a scheme from an image or generates one, with HEX, RGB, RGBA and HSL readouts.
Two audio tools are in preview: Wave takes MP3, WAV or AAC files, and Visualizer renders bars, a wave or a circle over artwork with title text, in 9:16, 1:1 or 16:9, and exports the clip as video. Dark by default with a light toggle, a collapsible sidebar grouped into Images and Audio, and a root URL that drops you straight into the compressor — there is no landing page.
Built on Next.js with React 19, Tailwind v4 and lucide icons; published under the Ryvio name and kept free with ads.
Highlights
- Optic: on-device image compression, no server round trip
- Vector: SVG optimizer with side-by-side preview and code output
- Palette: extract or generate schemes in HEX / RGB / RGBA / HSL
- Visualizer (preview): bars, wave or circle; 9:16, 1:1, 16:9; video export
- Tool-first: the root URL is the compressor, not a landing page
