Frequently Asked Questions
How does client-side compression work?
When you drop an image into Utility Den, HTML5 Canvas API decodes the image data locally. It adjusts the quantization tables and applies discrete cosine transform algorithms in your browser before re-encoding the result into optimized WebP or JPEG formats.
Why should I convert to WebP?
WebP is supported by all modern browsers (Chrome, Safari, Firefox, Edge, iOS Safari). It delivers 25%β35% smaller file sizes than JPEGs and 26% smaller than PNGs while supporting full transparency.
Is there any file size limit?
No. Because there are no backend server bandwidth costs or upload quotas, you can compress images of any size limited only by your computer or phone's available RAM.
Does this tool strip EXIF GPS location data?
Yes. Re-encoding on an HTML5 canvas discards all embedded EXIF metadata tags including camera serial numbers, exposure info, and GPS coordinates, ensuring complete privacy before publishing photos online.
