How to Compress JPEG Images and Balance Quality
Go to the JPEG compressorWhat Is JPEG Compression?
JPEG is a common image format for photographs. Litemio decodes a selected JPEG and encodes the pixels as a new JPEG, with a quality value you can adjust.
Why Compress JPEG Images?
A smaller image can be easier to store, send, or use on a page. The size change depends on the image and chosen quality; there is no guaranteed reduction.
How JPEG Compression Works
The browser decodes the image to pixels, then the JPEG encoder writes those pixels using the selected quality. Litemio keeps the image dimensions and uses a baseline, progressive JPEG encoding.
What Does JPEG Quality Mean?
Quality is the encoder setting from 1 to 100. Lower values usually create smaller files with more visible changes; higher values usually preserve more detail but may produce larger files. The default is 80.
How to Reduce JPEG File Size
Add one or more JPEG or JPG files, adjust Quality, and inspect the side-by-side preview. Apply the preview you want; if the encoded file is not smaller, Litemio keeps the original.
JPEG vs PNG
JPEG is often suitable for photographs when some image change is acceptable. PNG is lossless and supports transparency, which can suit screenshots, diagrams, and images with sharp edges. PNG compressor.
JPEG vs WebP
Both formats can encode photographs. WebP can also represent transparency and animation; JPEG is widely used for still photographs. Compare actual files and consider where they will be displayed. WebP compressor.
When Should You Use JPEG?
Use JPEG when you need a broadly recognized format for still photographs and do not need transparency or animation. Choose another format when those properties matter.
