Convert files from the right-click menu
Installing wandeln adds a Wandeln entry to File Explorer’s right-click menu. Only the actions that fit the selected files are shown.
| Action | What it does |
|---|---|
| Merge PDFs (PDFを結合) | Combines two or more selected PDFs into one. |
| Split into pages (PDFを1ページずつに分割) | Saves each page as its own PDF. |
Images
Section titled “Images”| Action | What it does |
|---|---|
| Convert to PNG / JPG / WebP | Changes the image format. |
| Shrink to 50% / to 1920px wide | Makes images smaller. |
| Combine into PDF (PDFにまとめる) | Turns the selected images into one PDF. |
| Action | What it does |
|---|---|
| Convert to MP3 (audio only) | Extracts just the audio. |
| Convert to GIF (first 15 s) | Turns the start of the video into an animated GIF. |
| Compress to 10 / 20 / 50 MB | Re-encodes to fit the size — handy for chat uploads. |
Output files are saved next to the originals (PDF splits go into a <name>_分割 folder). Selecting several files processes them together, with progress shown on the top bar.
If wandeln isn’t running, it does just the conversion without showing the bar, and quits when it’s done.
Video conversion uses the ffmpeg bundled with the installer — nothing extra to install.
