4.Converter Images

After installation, launch PiCode on your computer. You can choose to import files or folders from the menu.

You can also directly drag and drop files into the software, dragging images directly into the application.

After successfully importing the images, choose the desired format and compression settings in the bottom left corner.

In the Compression Settings dialog, you can configure image quality and various additional attributes.

Click the ‘Set Output Folder‘ button to configure the output directory.

Click the dropdown arrow in the directory bar to choose from your history paths.

If the ‘Save to Original Folder‘ option is selected, the images will be saved to their respective original directories. If the formats are the same, they will be overwritten.

When the ‘Copy Original Folder Structure‘ option is selected, the images will be output to a new directory following the original directory structure. This will only apply to images directly imported from folders.

Once the settings are configured, you can directly click the ‘Convert‘ button to start the image format conversion.

5.Merge Images

Use your mouse to draw a selection box around the images you want to merge, or hold down the CTRL key to individually select images. Then click the ‘Merge Images’ button to perform the merging operation.

Open the ‘Merge Images‘ dialog box, where you can adjust the image order using arrows. There are two export options:

• ‘Adapt to size (A4)‘: All page sizes will be A4 paper size, and images will be proportionally scaled to fit the page.
• ‘Original Size‘: Page sizes are not fixed, but generated based on image sizes.

Once the settings are configured, click the ‘OK‘ button to start the image-to-PDF merging process. After the merging is complete, the output directory will open automatically.
