Are images uploaded to a server?
No. UploadReady V1 processes selected images locally in your browser and does not store them.
Can I resize by percentage?
V1 uses pixel dimensions. Percentage resizing can be added later if users ask for it.
Can I keep transparency?
Choose PNG or WEBP output to keep transparency where the browser preserves it.
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.
