v1.0 — LocalPix replaces LocalConvert.
The first release under the LocalPix name. Same one-job-done-well utility, renamed and grown a little.
What it is
LocalPix is a local, offline image converter for macOS and Windows.
Drag images into the drop zone, pick an output format from the
row of buttons, click Convert. Output lands in
~/Documents/LocalPix/ by default, or wherever you tell
it to.
The whole product is a single hand-written HTML file wrapped by Electron, with a Node Express server handling the actual conversion. You can audit it in an afternoon.
Supported formats
Inputs: JPEG, PNG, WebP, AVIF, GIF, HEIF/HEIC, TIFF, BMP, SVG, PSD.
Outputs: JPEG, PNG, WebP, AVIF, GIF, TIFF, BMP, ICO. (JPEG XL was added in v1.1.)
What's in v1.0
- Initial release of LocalPix (rename from LocalConvert).
- Drag-and-drop with thumbnail previews.
- Segmented format selector, alphabetically ordered.
- Per-format options: JPEG quality + alpha background, PNG compression level, WebP quality + effort, AVIF quality + speed, GIF dithering + palette size, TIFF compression, ICO multi-size.
- Batch convert with a single button.
- User-selectable output folder via the Electron folder picker.
- Dark mode that follows the system, with a manual override.
- Menu actions: ⌘O Open files, ⌘⇧O Change output folder.
- SVG density control for rasterizing at the right resolution.
- Animated source flattening for GIF and animated WebP inputs.
Why the rename?
The app started as WEBPConvert — a single-format
command-line script. It outgrew the WebP-only name and became
LocalConvert. Then it outgrew that too: "convert"
isn't the differentiator. Local
is. The new name says what makes this thing different from the
fifty online converters you'd find with one search.
WebP output is byte-identical across all three names, so existing users with pinned hashes don't need to change anything.
Privacy
No analytics, no telemetry, no upload, no account. The same as every release before it; the same as every release after. Disconnect from the internet — LocalPix keeps working.
Install
Download the macOS .dmg or Windows .exe, then follow the platform-specific install steps. macOS and Windows will both warn about an unsigned app — that's because LocalPix hasn't paid for a $99/$300 certificate, not because the app is doing anything questionable.
