To make digital artwork ready for sharing online and in portfolios, there are several important things to consider:

1. Pick the Right File Type

• JPEG: Great for photos and detailed images. It reduces file size a lot (up to 90%), which is helpful.
• PNG: Good for images that need a transparent background. It keeps high quality without losing any details, but the file sizes are usually bigger than JPEG.
• GIF: Good for simple pictures and animations. It can only show up to 256 colors, though.
• TIF/TIFF: Best for high-quality prints, but these files can be large and not the best for sharing online.

2. Resolution is Important

• For online use, pictures should be set at 72 DPI (dots per inch). This quality is enough for screens.
• For printing, images should be saved at 300 DPI or higher to keep them looking good.

3. Compression Methods

• Lossy compression (like JPEG) can make the file size smaller but may lose about 10–30% of the quality.
• Lossless compression (like PNG) keeps all the details but usually means bigger file sizes.

4. File Size Guidelines

• Try to keep file sizes under 1 MB for faster loading times. This is really important for online portfolios.
• Research shows that 40% of people leave a page that takes longer than 3 seconds to load, so keeping file sizes small is a must.

5. Use Metadata

• Add metadata (like title, artist name, and copyright info) to your art files. This adds context and helps protect your work.

By choosing the right file formats, using the best resolutions, carefully applying compression, and adding metadata, artists can get their digital artwork ready for online sharing. This helps them stand out and look professional in the digital world.
