Method 1: imagetosvg.com Pro Batch API

imagetosvg.com Pro offers a batch conversion API for high-volume workflows.

Upload multiple images via the API endpoint with API key authentication
Specify per-image settings (preset, color count) or apply defaults
Results returned as SVG download URLs or base64 SVG data
Rate limits: up to 100 concurrent conversions per batch
Webhook support: get notified when batch completes, no polling needed

Method 2: Inkscape CLI Batch Script

Inkscape's command-line interface enables scripted batch conversion from any raster format.

Shell: for f in *.png; do inkscape "$f" --export-plain-svg="${f%.png}.svg"; done
PowerShell: Get-ChildItem *.png | ForEach-Object { inkscape $_.Name --export-plain-svg "$($_.BaseName).svg" }
Control settings: add --export-dpi=300 or specific Inkscape parameters
Parallel processing: use GNU parallel or xargs -P4 for 4 simultaneous conversions
Limitation: Inkscape's built-in tracer (Potrace) â€” use imagetosvg.com API for VTracer quality

Method 3: Python Script with imagetosvg.com API

Automate batch conversion using the imagetosvg.com API in Python.

import requests, pathlib
for img_path in pathlib.Path('./images').glob('*.png'):
response = requests.post('https://imagetosvg.com/api/convert', files={'image': open(img_path,'rb')}, headers={'Authorization': 'Bearer YOUR_KEY'})
svg_path = img_path.with_suffix('.svg')
svg_path.write_text(response.json()['svg'])
Add error handling, retry logic, and checkpointing for >50 images

Frequently Asked Questions

Is there a free batch conversion option?

Free accounts are limited to 5 conversions per day, one at a time. Pro accounts include the batch API for automated multi-image conversion workflows.

How do I handle errors in batch conversion?

Implement retry logic with exponential backoff. Save successful conversions to a checkpoint file. Log failed files for manual review. Never assume all conversions succeed in batch workflows.

What's the maximum number of images I can batch convert?

imagetosvg.com Pro supports batches of up to 100 images per API call with no daily cap. For larger volumes, paginate your batch calls or use the streaming API.

Can I batch convert with different settings per image?

Yes via the API â€” each request in a batch can specify different preset, colorMode, and colorCount parameters per image.

How do I maintain folder structure when batch converting?

In your script, replicate the input directory structure for output. Use os.makedirs(output_path, exist_ok=True) in Python before writing each SVG to mirror the input folder hierarchy.
