Frequently Asked Questions — WebP Converter
Clear answers to common questions about methodology, edge cases, and privacy.
Why does Google PageSpeed recommend WebP?
WebP typically delivers 25%–35% smaller file sizes than comparable JPEG images and 26%+ smaller sizes than PNGs.
Are my images uploaded to any cloud server during processing?
Never. The WebP Image Converter decodes and re-encodes images directly inside your browser using the HTML5 Canvas API and local Blob URLs, ensuring complete privacy and zero upload latency.
Does client-side conversion strip EXIF metadata automatically?
Yes. Rendering an image onto an HTML5 Canvas and exporting a new JPEG, PNG, or WebP file naturally strips embedded camera EXIF and GPS location metadata.
