AI 업스케일링: 벡터화 전에 이미지를 확대해야 할 때와 방법

The quality of an SVG conversion depends heavily on the input image quality. A 100x100 pixel logo produces rough, blocky vectors. The same logo at 800x800 produces clean, smooth curves.

AI upscaling bridges this gap by generating a higher-resolution version with added detail.

When Upscaling Helps

• Small logos from websites (favicons, avatars) — often 32x32 or 64x64 pixels
• Thumbnails from e-commerce catalogs or social media
• Screenshots of text or UI elements
• Old scans of printed materials at low DPI
• Cropped portions of larger images

When Upscaling Does NOT Help

• Already high-resolution images (1000px+) — the vectorizer has enough data
• Photos traced as simple shapes — the vectorizer simplifies anyway
• Heavily compressed JPEGs — upscaling amplifies artifacts

Rule of thumb: under 500px, upscale first. Over 1000px, go straight to vectorization.

How VectoSolve Upscaling Works

VectoSolve offers a 4x crisp upscale optimized for images that will be vectorized afterward — preserving sharp edges unlike generic upscalers.

Using the Web App

1. Go to vectosolve.com
2. Upload your image and select Upscale
3. Download, re-upload, and select Vectorize

Using the SDK (Chain Operations)

import VectoSolve from '@vectosolve/sdk';
const client = new VectoSolve({ apiKey: process.env.VECTOSOLVE_API_KEY });

// Step 1: Upscale ($0.15)
const upscaled = await client.upscale('./tiny-logo.png', { scale: 4 });
// Step 2: Vectorize ($0.20)
const svg = await client.vectorize(upscaled.data.image);
// Total: $0.35 for high-quality SVG from tiny input

The Optimal Workflow

1. Assess the input. Under 500px? Visible pixelation? Upscale first.
2. Upscale to 4x. A 200x200 image becomes 800x800.
3. Choose the right vectorization mode. Standard for general use, Cricut for cutting machines, Laser for engraving.
4. Review and edit. Use SVG Studio to fine-tune.

Batch Upscaling

Use the batch API endpoint:

POST /api/v1/batch
{"images": [
  {"url": "https://example.com/icon1.png", "operation": "upscale"},
  {"url": "https://example.com/icon2.png", "operation": "upscale"}
]}

Upscaling uses 0.15 credits per image and vectorization 0.20 credits, so the full pipeline for 100 SVGs uses 35 credits. API credits are sold in lots on the developers page, from $19.99 for 100 conversions.

Comparing Upscaling Services

VectoSolve combines upscaling and vectorization on the same platform.
