Supports JPG, PNG, WebP
PNGs are converted to WebP for effective compression. JPEG/WebP stay as-is.
How to Use This Image Compressor
Reduce image file sizes quickly and easily without losing noticeable quality. All compression happens directly in your browser -- your images never leave your device.
- Drag and drop one or more images into the upload area, or click to browse files
- Adjust the quality slider to control the compression level (lower = smaller file)
- Click "Re-compress All" to apply a new quality setting to existing images
- Download each compressed image individually
Lower quality values produce smaller files but may introduce visible artifacts. For most use cases, a quality of 70-85% provides an excellent balance between size and quality.
FAQ
Is my image uploaded to a server?
No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device and are not sent to any server.
What image formats are supported?
This tool supports JPEG, PNG, and WebP images. The compressed output will match the original format.
Why is the compressed file sometimes larger?
This can happen when using "Keep Original" format with PNG images, since PNG uses lossless compression. The default "Auto" format avoids this by converting PNGs to WebP for effective compression.
Can I compress multiple images at once?
Yes. You can drag and drop or select multiple images simultaneously. Each image will be compressed individually with the same quality setting.
