This guide will teach you everything there is to know about optimizing the file size of your images, while still maintaining a visually high-quality image that loads quickly.

Why Image Size Matters

Website Performance and User Experience

This can hugely impact on loading time of your website in today, users want the moments transition and If you have very big images than your site took too much time to load then user will leave before they see what actually in side it.

If you reduce the Image resolution, then file size is reduced drastically. The larger the resolution, the bigger file size. Depends on where your image will appear, if it is digital you can forget about print resolution (300 DPI). While the screens will display them fine, this might not result in a poor screen quality as opposed to print ppi or dpi.) But lowering resolution down to 72 DPI can be great for keeping file sizes low.

Steps to Adjust Resolution:

Open the image in your editing software.
Go to the “Image Size” or equivalent menu.
Reduce the resolution (measured in DPI).
Save or export the image.

Reducing the resolution is particularly useful for web images, where high resolution is unnecessary. However, if you’re printing the image, it’s important to maintain a higher resolution to ensure print quality.

4. File Format Conversion

Choosing the right file format can also help reduce image size. Different formats offer varying levels of compression and quality retention.

JPEG: Good for photos and images with gradients. It is a lossy compression that sheds some image data to lease memory. This may result in a small drop in quality, which is often undetectable unless the image has been compressed greatly.
PNG: Meanwhile, this is best for images that has transparency and images with sharp edges enough so you could put texts on it. It is quite obvious that PNG uses only lossless compression, thus it will preserve al image data and cutting with nowhere the file size like JPEGs. The choice for logos, icons and images that need high quality.
WebP: Developed by Google, WebP is a relatively newer format that provides better compression over JPEG and PNG high quality. Versatile, supports lossy and lossless compression: An all-around good choice for web images
