What it does
-
Remove background — a neural network separates
the subject from any background, or an instant threshold mode for
line art on plain backgrounds.
-
Resize — to exact dimensions, a scale factor,
or a whole set of square sizes at once, using Lanczos or bicubic
resampling.
-
Favicon — packs every standard icon size into
a single
.ico file.
Nothing leaves your machine
Romendil does all its work locally. Your images are never uploaded, there
is no account, no telemetry, and no network connection is required. The
neural network model ships inside the app, so it works offline from the
first launch.
Notes
-
The download is large because the app carries its own Python runtime
and the background-removal model. Nothing needs installing separately.
-
On Linux, mark the AppImage executable before running it:
chmod +x Romendil-*.AppImage
-
Windows SmartScreen may warn on first run, as the installer is not
code-signed. Choose More info → Run anyway.
