Resize and compress photos in bulk on Windows
Phone photos are often 5–10 MB each. Make a whole folder small enough to email or upload, in one go.
How to do it with S Converter
- Open S Converter and choose Compress in the sidebar.
- Drag in your photos or a folder.
- Pick a Max width (1920px suits most screens) and adjust Quality.
- Press Convert. You’ll see how much space you saved.
Or use a one-click preset
- Select the photos in File Explorer and press Ctrl + Alt + C.
- Switch to Presets on the wheel and click Email, Web or Compress.
The shortcut works while S Converter is running (it waits in the system tray). In the version from GitHub you can also right-click files and choose S Converter; on Windows 11 it's under Show more options.

Questions
Will my originals be changed?
No. Smaller copies are saved next to them; the originals are never overwritten.
Which size should I pick?
1920px wide is plenty for screens and email; 1280px is lighter still for websites.
