Compress multiple images quickly in your browser without waiting for uploads.
All processing happens locally on your device, so your files stay private.
Adjust the quality slider to balance file size and visual quality for each workflow.
Lossy compression removes some image data to create a smaller file, while lossless compression keeps all original data. JPG and WebP often benefit most from a quality slider, while PNG usually stays lossless.
PNG is designed for lossless quality, so the browser quality parameter does not affect it. PNG compression gains are usually smaller unless metadata is removed or the image is converted to another format like WebP.
The quality slider controls JPEG and WebP re-encoding quality. Lower values usually create smaller files, while higher values preserve more detail.
For most web images, 70% to 85% is a strong starting point. It usually reduces size noticeably while keeping the image visually sharp.
You can add multiple files in one session. Very large batches depend on your device memory and CPU, since everything runs inside your browser.
