How to batch recolor SVG icons in seconds (free, no signup)
Inherited an icon set in the wrong colors? Need to match a brand palette across 50 SVGs? Doing it one-by-one in Figma takes hours — open file, select path, change fill, save, repeat.
Here's a faster way using Color Swap — upload your SVGs, the tool auto-detects every color, you pick replacements, it exports a ZIP. Free, no signup.
The problem with existing methods
Manual (Figma / Illustrator)
→ Open each file individually
→ Click every path, change fill
→ Miss elements, discover later
→ 30+ icons = an afternoon gone
→ No undo across files
Color Swap
→ Upload all SVGs at once
→ Every color detected automatically
→ One click replaces across every file
→ Live preview before export
→ ZIP download, free forever
Files never leave your browser — processing happens locally. No signup, no upload limits within reason (50 files, 5MB each).
Step-by-step: batch recolor SVG icons
1. Drop your SVGs
Open swap.ohiyo.app and drop an SVG file — or a whole folder. The tool handles batches up to 50 files at once.
2. Every color appears in a palette
Color Swap scans every fill and stroke across all your files and lists the unique colors. If 20 icons share a shade of blue, it shows up once.
3. Click a color to replace it
Pick any color in the detected palette, choose a replacement. The preview updates for every file instantly. Replace multiple colors before exporting — perfect for converting a light-mode icon pack to dark mode.
4. Download the ZIP
Hit Export. You get a ZIP with all your recolored SVGs, original filenames intact. Drop straight into your Figma library or project folder.
Common use cases
- Brand palette match — downloaded a free icon pack but the colors don't match your brand? Swap in one click.
- Light mode → dark mode — invert all dark icons to light variants for your dark theme.
- Theme variants — generate blue / green / purple versions of the same icon set for product themes.
- Unify from multiple sources — combined icons from Lucide, Heroicons, and custom SVGs into one consistent palette.
- Client work — client asks "can we see this in our brand colors?" — 30 seconds vs 2 hours.
About the pricing
Straight-up: Color Swap is free. No Pro tier, no upgrade prompt, no trial. Upload, recolor, download.
Why free: it's a simple tool that doesn't take much to run, and it doubles as a way to show you what AutoKit and IsoKit do if you ever need more than just recoloring.
