How Images Are Formatted

Digital pictures are made out of millions of tiny squares called pixels. Every pixel holds information about its color and transparency. When you change an image from one format to another, you change how this pixel data is saved and stored on your device.

Lossy vs. Lossless Formats

Choosing the right format depends on whether you want to save space or keep original quality:

• Lossless Formats (PNG, TIFF, BMP): These keep every single pixel exactly as it was originally made. They do not lose any quality, which makes them perfect for screenshots, text, and logos.
• Lossy Formats (JPEG, WEBP, AVIF, HEIC): These make image files much smaller by removing minor color details that the human eye can barely see. This lets you save a lot of storage space while keeping the picture looking clear.

Why Modern Formats Are Better

Older formats like BMP or TIFF usually create massive files that take up too much storage and slow down websites. Switching to newer image styles like WEBP or AVIF can cut file sizes down by 30% to 50% compared to old JPEGs. This helps web pages load much faster and saves your internet data.

Most online converters make you upload your photos to their servers, which can put your privacy at risk. The AKeyUP image converter works 100% inside your own browser. Your files are never sent to the internet, keeping your personal photos private, safe, and completely secure.
