Image utility
Compress images
Reduce image file size locally in your browser. Choose quality, format and optional resizing.
Select images
JPEG, PNG and WebP. You can choose multiple files.
Selected files
Compression settings
Quality applies to JPEG and WebP. PNG is re-encoded without a quality slider.
Lower values usually create smaller files with more visible loss.
Resize and format details
Aspect ratio is preserved. Images smaller than both limits are not enlarged.
JPEG cannot store transparency; transparent pixels are filled with white.
Re-encoding may remove or change metadata, embedded profiles and DPI information. The visible EXIF orientation is applied when decoding.
Animated PNG or WebP files are rejected because this compressor outputs a single still image.
How local processing works
Selected image bytes are decoded and re-encoded by browser APIs on this device. This tool does not send the selected file, its bytes, a Base64 copy or derived image data to a processing server.
