JPG Compressor
Reduce JPG file size with adjustable quality and instant browser-side processing.
ℹ️ About JPG Compressor
JPG Compressor is a focused version of our image compression tool built specifically for JPG and JPEG photographs. Photos from phones and cameras are often several megabytes in size, which is far more than most websites, forms or messaging apps need. This tool re-encodes your JPG at an adjustable quality level entirely in your browser, letting you shrink file size dramatically while keeping the photo looking sharp. A live before-and-after preview shows you the trade-off as you adjust the slider, so there's no guesswork involved.
🛠️ How to Use JPG Compressor
Choose your JPG or JPEG photo, then adjust the quality slider while watching the live preview and estimated file size above it. Lower values produce smaller files with more visible compression; higher values keep more detail. Once the result looks right, click Download to save the compressed JPG.
