Frequently Asked Questions
Is my image uploaded to a server?
No. This tool is 100% private. All image compression, resizing, and conversion happens client-side directly in your browser. Your images never leave your device.
What image formats are supported?
You can upload JPEG, PNG, and WebP images. You can also convert between these formats (e.g. convert a PNG into a WebP).
Does compressing reduce image quality?
Slightly, but we use smart canvas-based compression algorithms. Setting the quality to 70-80% usually reduces the file size by 50-80% without any noticeable loss in visual clarity.
Can I resize the width and height?
Yes, you can scale the image size by percentages or input a specific custom width and height. We also provide common social media presets.
