Convert files
The main window has three parts: categories on the left, your files in the middle, and Output settings on the right.
Convert in four steps
- Choose a category on the left: Images, Audio, Video, Documents, PDF Tools or Compress.
- Drag files or whole folders into the window, or press Browse files. Files of another kind go to their own category automatically.
- On the right, pick a Format (for example JPG, MP4 or PDF) and adjust the options.
- Press Convert. The button shows how many files will be converted.
When it's finished, the Conversion complete screen shows every new file, how much space you saved, and buttons to open them or show them in their folder.
Output settings
| Setting | Where | What it does |
|---|---|---|
| Format | all | The file type to make |
| Quality / Max size | Images, Compress, Video | Quality of the result, or a maximum file size |
| Bitrate | Audio | Sound quality for MP3, AAC and similar |
| Resolution | Video | 4K, 1080p, 720p, 480p or 360p, or the original |
| Max width | Compress | Make large photos smaller in pixels too |
| Edit | Images, Video, Audio | Trim, watermark and rename |
| Save location | all | Next to the originals, or one folder you choose |
Where converted files go
By default, new files are saved next to the originals with SC added to the name, for example Holiday.heic → HolidaySC.jpg. Nothing is ever overwritten. Switch off Save at source folder to save everything into one folder instead, and press Change to pick it.
One-click presets
When files are added, a One-click row appears above the list: Email, Instagram, Web, Compress, Thumbnail, Private copy, Under 100 KB, Form photo for images, and similar presets for video, audio and documents. A preset converts straight away with settings made for that job. See Presets and recipes.
Preview
Press Preview to look at a file before converting. For watermarks, the preview shows the watermark exactly where it will be.
Pause and cancel
While converting you can Pause (the current file finishes first) or Cancel. When you cancel, the half-made file is removed, and files that already finished are kept.
Tips
- Drop a folder to add every supported file inside it.
- iPhone HEIC and camera RAW photos convert to JPG, PNG, WebP and others.
- For video, S Converter uses your NVIDIA, Intel or AMD graphics card automatically, which is usually several times faster.
