Are images uploaded to a server?
No. UploadReady V1 processes selected images locally in your browser and does not store them.
Does WEBP keep transparency?
Yes, WEBP supports transparency, and the browser preserves it for many PNG files.
Why convert PNG to WEBP?
WEBP is often smaller than PNG for web graphics and screenshots.
What formats are supported?
V1 supports JPG, PNG, WEBP and best-effort HEIC/HEIF conversion where your browser and file allow it. PDF tools are intentionally not included in this first image-focused release.
