Notes

Images are decoded, resized, and re-encoded inside your browser; the page never sends an upload request.
Compression strips EXIF metadata (including location) and keeps only pixel data.
Browsers cannot decode HEIC photos from iPhones; export as JPG first.
With “Keep original format”, PNG goes through lossless optimisation and pixels do not change; converting to WebP or JPEG is lossy.
