What changes

  • ICO pixels are decoded and encoded as JPEG by our image engine for ico-to-jpg; no OCR is performed.
  • EXIF, color profiles, layers, animation frames, and camera metadata may be stripped unless the destination requires minimal metadata.
  • Transparency stays for PNG and WebP but is filled with the selected background for JPEG, BMP, PDF, and other opaque targets.
  • Animated inputs such as GIF are flattened to a still frame unless a server codec explicitly supports animation for that output.
  • SVG input is rasterized at the requested dimensions or DPI, producing pixels rather than editable vector paths.
  • This pair runs in a browser worker first, so standard web conversion does not upload the file.

A real ICO → JPEG run

We converted our ICO sample (12 KB) with Image engine on 2026-10-20. It took 9 ms and produced a 5 KB JPEG file, 53% smaller than the input. The engine raised 2 warnings, listed below.

  • Transparency filled with #ffffff for JPG output.
  • Image metadata stripped from output.

Options

width
Set the output width in pixels.
height
Set the output height in pixels.
fit
Contain, cover, or fill within the requested dimensions.
quality
Set lossy output quality where the codec supports it.
background
Fill transparency with this color for opaque formats.
stripMetadata
Remove source metadata when writing the output.
dpi
Rasterize SVG or PDF-derived pixels at the requested scale where supported.

Example

input
ICO image, 1200 × 800 pixels
output
JPEG image resized or re-encoded without OCR text extraction

Do it in code

python
from PIL import Image
img = Image.open("input.ico")
img.save("output.jpg")

ICO to JPEG by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Image engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=ico&to=jpg.

curl
curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.ico" -F "from=ico" -F "to=jpg" \
  -F 'options={"dpi":96}' \
  --output output.jpg
