Frequently asked questions
How can I compress an image without uploading it?
Open your photo on this page. Compression takes place in your browser, and the resulting file downloads directly to your device.
Can I reduce image size without losing quality?
JPG and WebP compression in this tool can lose detail. Compare the preview and choose a balance between quality and file size. We do not promise lossless compression.
Why is my compressed image sometimes larger?
Re-encoding an already optimized file can make it larger. We show the actual file size and flag results that are not smaller. Try reducing quality or dimensions.
What happens to transparency?
WebP preserves transparency. JPG does not support it, so the tool adds a white background. Animated files are not supported.
