What each setting does

Sketchy gives you four sliders and a mode switch. Here is exactly what each one controls and when to adjust it.

01

Colors

How many colours appear in the output. 2–6 for flat logos and icons, 12–32 for illustrations with more depth. More colours = larger file.

Start at 6 for logos, 12–16 for illustrations.
02

Detail

Controls edge sensitivity and region granularity. Lower values ignore subtle variations and produce cleaner, more graphic results. In Line Art mode, lower = fewer edges detected.

70% default. Drop to 40–50% for cleaner logos.
03

Min Region

Filters out regions smaller than this size in pixels. Removes stray pixels, antialiasing artefacts, and JPEG noise from the output.

Raise to 20–40px for noisy photos.
04

Smoothing

Blurs the image before conversion to reduce noise and compression artefacts. Higher values = cleaner region edges, less fine detail.

Level 1 for clean art. Level 3–5 for photos.
Auto — Flat Color Regions

Quantises the image into a colour palette and fills each region with a flat colour. Best for logos, icons, illustrations, and any image with distinct colour areas. Produces compact SVG files with grouped colour layers. Adjust Colors and Min Region for the best balance of fidelity and cleanliness.

Line Art — Edge Detection

Runs Canny-style edge detection on the image and traces the result as black strokes on a white background. Best for hand-drawn sketches, pencil drawings, diagrams, and outlines. The Detail slider controls edge threshold — lower values catch more edges including faint ones. Smoothing reduces noise before detection.

Built for speed, privacy, and quality

No subscriptions, no sign-ups, no file size limits. Just fast, clean SVG output that scales infinitely.

Zero-Upload Privacy

Your images are processed entirely inside your browser. Nothing is ever sent to a server — not even a single pixel. You can disconnect from the internet and it still works.

Background Processing

Conversion runs in a dedicated background thread so the page stays responsive. Progress updates in real time and you can cancel at any point without freezing your browser.

Infinite Scalability

SVG files scale to any resolution — from 16px favicon to billboard — without pixelation. Perfect for logos, icons, illustrations, print, and web graphics.

Multiple Formats

Upload PNG, JPG, WEBP, GIF, or BMP. Sketchy reads them all natively through the browser's built-in image decoders and converts to clean SVG every time.

Tunable Quality

Four independent parameters give you precise control over colour depth, detail level, region filtering, and noise reduction — for output that matches your exact needs.

Clean SVG Code

Output is standard SVG 1.1 XML — no proprietary encoding, no embedded rasters. Copy the code directly, embed it in HTML, or open it in any vector editor.

Who uses Sketchy — and why

From logo designers to developers to content creators — anyone working with images on the web benefits from scalable vector output.

Logo & Brand Design

Convert scanned hand-drawn sketches or low-res logos into clean SVG vectors ready to scale to any size for print or digital use.

Web Development

Replace heavy PNG assets with lightweight inline SVGs that render crisply on retina displays and improve Core Web Vitals scores.

App UI & Icons

Turn any reference image into an icon-friendly SVG. Reduce colour count to get clean, flat single-pass vector icons for iOS, Android, or PWAs.

Print & Merchandise

Prepare artwork for sublimation printing, vinyl cutting, or screen printing. SVG files scale to any size without quality loss.

Illustration & Sketches

Use Line Art mode to extract crisp outlines from photographs or scanned drawings. Import the SVG into Inkscape or Illustrator for further work.

Sensitive & Private Work

Working with confidential documents or proprietary artwork? Sketchy never uploads anything — convert with complete peace of mind.

Frequently asked questions

Is Sketchy really free with no limits?
Yes, completely. There are no file size limits, no daily conversion limits, no watermarks, and no account required. Sketchy is part of the RuntimeHub suite of free browser-native tools.
Does my image get uploaded to a server?
Never. Sketchy runs entirely in your browser. When you select a file it is read into browser memory only — no data is transmitted over the network at any point. You can verify this by opening the Network tab in Developer Tools before converting — you will see zero outbound requests containing image data.
What image formats are supported?
Sketchy accepts any image format your browser can decode: PNG, JPG/JPEG, WEBP, GIF (first frame), and BMP. If your browser can display it, Sketchy can convert it.
Why does my conversion look blocky or noisy?
For noisy photos or JPEG images, try increasing Smoothing to 3–5 and raising the Min Region slider to 20–40. This filters out compression artefacts before conversion and removes tiny stray regions from the output. Reducing the Detail slider also helps by ignoring minor colour variations.
Which mode should I use for a logo?
Use Auto mode with a low colour count (2–6) and a high Min Region value (20–40). This produces clean flat colour regions with no noise. If the logo is a black line drawing on white, Line Art mode will give the sharpest outlines.
How many colours should I use?
For icons and logos, 2–6 colours produce the cleanest flat vector graphics. For illustrations, 8–16 colours balance fidelity and file size well. For stylised photo results, 20–32 colours preserve more visual complexity. More colours means a larger SVG file.
Can I edit the SVG output?
Yes. The output is standard SVG XML that opens in any vector editor including Inkscape (free), Adobe Illustrator, Affinity Designer, and Figma. You can also embed it directly in HTML.
Can I use the SVG output commercially?
Sketchy places no restrictions on the output files — the SVG belongs to you. However, ensure you own or have the rights to the source image. Converting a copyrighted image to SVG does not transfer ownership of the underlying content.
