 ## Why DropSlim
 
 - **Drag & drop** — drop files or folders on the window; whole folders are processed recursively
 - **Small and fast** — lightweight app, fast compression; built with imagequant, oxipng, zenjpeg, OXVG, gifsicle, WebP, and AVIF encoders
-- **Runs offline** — no internet required; compression runs entirely on your Mac
+- **Runs offline** — no internet required; compression runs entirely on your computer
 - **Privacy** — no upload, no tracking; your images never leave your machine
 - **Batch processing** — hundreds of files in one go; new file alongside the original, or replace in place
-- **All common formats** — PNG, JPEG, HEIC, GIF, SVG, WebP, and AVIF
-- **Open with DropSlim** — right-click an image in Finder → **Open With** → DropSlim
-- **Review results** in a simple list and reveal outputs in Finder
+- **Common formats** — PNG, JPEG, GIF, SVG, WebP, and AVIF. **HEIC on macOS only**
+- **Open with DropSlim** (macOS) — right-click an image in Finder → **Open With** → DropSlim
+- **Review results** in a simple list and reveal outputs in Finder or File Explorer
 - **Open source** — [MIT](LICENSE.md)
 - **Languages** — English, German, French, Spanish, Italian, Japanese, Brazilian Portuguese
 
 ### Where the optimized file is saved depends on your settings
 
 - **`.min` suffix on** (default): writes a new file next to the original, e.g. `photo.png` → `photo.min.png`. The source file stays untouched.
-- **`.min` suffix off**: replaces the original file in place with the optimized version.
+- **`.min` suffix off**: overwrites the original in place when saving in the same folder and **`minified` subfolder** is off. With the subfolder on, the optimized file goes into `minified/` under the original filename and the source stays untouched.
 - **`minified` subfolder**: saves into a `minified/` folder (with or without `.min`, depending on the suffix setting).
 - **Custom save folder**: turn off **Save optimized files in same folder** in Settings — **Choose folder** appears; click **Open** to pick a destination.

 ## A Frustrating Side Note
 
-DropSlim is open source and free. Nevertheless, in the Apple ecosystem, it apparently costs money just to download an app, drag it into the “Applications” folder, and open it without any further hassle.
+DropSlim is open source and free. Nevertheless, it appears that on both major desktop platforms, it costs developers money to allow users to simply download, install and open an app without any further hassle.
 
-That’s because Apple requires me to join its paid Developer Program, which costs 99 EUR per year. On top of that: identity verification with a wait time of 5 days, certificate signing requests, Developer ID certificates, app-specific passwords, authorizations, and a registration process that feels like the administration from “Asterix Conquers Rome” digitized the A38 pass to make breathing fresh air subject to approval.
+**On macOS**, Apple requires a paid Developer Program (99 EUR per year). On top of that: identity verification with a wait time of 5 days, certificate signing requests, Developer ID certificates, app-specific passwords, authorizations, and a registration process that feels like the administration from "Asterix Conquers Rome" digitized the A38 pass to make breathing fresh air subject to approval. This project covers that fee, so Mac users get a normal install.
 
-None of this makes the app any better. It merely serves to satisfy Gatekeeper so that app users aren’t greeted with _“Apple couldn’t verify…”_ and a useless “Done” button, only to then have to click an “Open Anyway” button buried deep in the security settings.
+**On Windows**, SmartScreen treats unsigned installers as suspicious. A commercial code-signing certificate (roughly 100+ EUR per year, from a certificate authority or cloud signing service) is the paid entry ticket to a smoother path; even then, reputation builds slowly and rarely helps a small open-source project. This project does not pay for Windows signing — use **More info** → **Run anyway** (steps above). The installer is still safe if you download it from this repository or the [project website](https://dropslim.app/).
 
-This project covers that fee, so you don’t have to worry about it. If any developer knows a trick to bypass the Developer Program without compromising the installation process, I’d be very happy to hear from you :)
+None of this makes the app any better. It only buys a smoother install experience. If you know a legitimate way around either gate without compromising security, I’d be happy to hear from you :)
