Single-file browser tool that decodes a base64 string and saves the
result back out as a file. No server, no dependencies, nothing uploaded.
Input cleanup covers data URIs, URL-safe alphabet, missing padding,
line wrapping, percent-encoding and wrapping quotes. Type detection
runs magic bytes (~30 signatures), then the data URI's declared MIME,
then UTF-8 content sniffing for SVG/HTML/XML/JSON/PEM; unrecognised
payloads fall back to .bin with a hex dump. Images, audio, video, PDF
and text are previewed inline before download.
C++ WebView2 host app driving a Python/rembg engine as a JSON-stdio
sidecar, with live before/after preview for images and video frames.
Also includes the original CLI (removebg.py) built on the same
core/ engine.
The WebView2 SDK is fetched on demand via
native/third_party/fetch-webview2.ps1 (wired into the Makefile)
rather than vendored, since it's ~15MB of prebuilt/generated
Microsoft SDK content. A Makefile provides make sync/build/run/clean
as the standard entry points.
Add tool description covering auto-detection behviour, the ComfyUI and
Ollama model payload, skip-if-present logic, build/run instructions, and
the Windows requirement.
