Getting Started

This guide walks you through compressing your first batch of images.

1. Install the app

Download and install Batch Compress Image from the Microsoft Store. Once installed, launch it from the Start menu.

2. Select your input folder

Click Browse next to Input Folder and choose a folder containing your source images.

Supported formats: JPG, PNG, WebP, TIFF

The app scans the folder, counts supported images, and loads sample files for the preview panel.

3. Choose your output format

You can keep each file in its original format or convert the whole batch.

Format Best for
Same as Input Keep the current format of each image
JPG Small files for photographs and general sharing
PNG Lossless output for graphics, screenshots, and transparency
WebP Strong compression with good quality for modern workflows

See Output Formats for the details.

Note: TIFF input is supported, but TIFF files are exported as JPG when you choose Same as Input.

4. Set compression quality

Use the Quality slider to control how aggressively the app compresses the images.

  • Higher values keep more detail and produce larger files
  • Lower values create smaller files but may add visible artifacts
  • The slider applies to JPG and WebP output
  • PNG output is lossless, so the slider does not apply
  • In Same as Input mode, quality only affects JPEG and WebP source files

A good starting point is 80%, which is the app default.

5. Configure output options

The Output card lets you control where the compressed files go and how they are named.

  • Folder - subfolder created inside the input folder. Default: compressed
  • Suffix - optional text added before the file extension
  • Skip already compressed files - prevents reprocessing files that already exist in the output folder

Example:

photo.jpg -> compressed\photo.jpg
photo.jpg with suffix _web -> compressed\photo_web.jpg

6. Decide whether to strip EXIF metadata

Turn on Strip EXIF metadata if you want to remove embedded metadata such as camera details, timestamps, and GPS data from exported files.

Leave it off if you want to preserve the original metadata.

7. Check the preview

The preview panel shows a sample image from the selected folder using your current settings.

  • Compressed shows the exported result
  • Original shows the source image
  • Split shows both side by side

Use Previous, Next, and Refresh to inspect other files before running the full batch.

If the selected sample can be previewed, the panel also shows a Preview estimate line so you can see the likely size change before processing the whole folder.

8. Compress the folder

Click Compress Images to start.

While running:

  • A progress bar shows overall completion
  • The current filename is displayed
  • You can cancel the batch at any time
  • The Activity Logs panel records per-file success, skipped files, and errors

When the run finishes:

  • Review the final summary line for original size, final size, and total bytes saved
  • Open Activity Logs if you want the detailed per-file history
  • Click Open Output Folder to see the results

Tips

  • Start with 80% quality and preview a few representative files before compressing a large folder
  • Use the preview estimate as a quick sanity check before you commit the whole folder
  • Use PNG for screenshots, UI captures, logos, or text-heavy graphics
  • Use JPG or WebP for photographic content
  • Turn on Skip already compressed files if you are retrying a partially completed batch
