Basic Image Compression

Zipic supports compressing multiple images and all images in specified folders. Currently supported formats include JPEG, PNG, WebP, GIF, HEIC, AVIF, TIFF, ICNS, with more formats planned.

General Steps

Follow these steps to compress images with Zipic:

1. Set compression options: This step can be skipped if you want to use the last saved settings.
2. Choose compression method: Select a method to start compression.
3. View compression results: Check the results in the history list. Click the thumbnail to see a comparison preview. If unsatisfied, repeat steps 1 and 2.

Tip

Usually, we click the Compression Settings button at the bottom left of the main window for quick settings instead of opening the settings window.

Compression Options

Click the Compression Settings button at the bottom left of the main window to open the compression options window.

In this window, you can set four groups of compression options:

Compression Level

Set a reasonable compression level to balance image size and quality. We recommend level 2 or 3. Higher levels mean lower quality but smaller size.

Save To

Configure where to save the compressed images, whether replacing the original, saving to a specified directory, or adding a suffix. See Save Options for details.

Save Format

Set the target format for compression. Supports converting to JPEG, WebP, HEIC while compressing. See Compression Formats for details.

Resize

Set the target size for compressed images. By default, the original aspect ratio is maintained. Setting width will auto-adjust height and vice versa. See Resizing Images for details.

Tip

First-time users should start by setting the compression level and get familiar with the process. Other options can remain default.
