No signup is required. Images are processed locally and are never uploaded. JPG, PNG, WebP, HEIC and AVIF still images are supported, including batches of up to 50 files.

Are my images uploaded?

No. Processing happens locally in your browser. PlainImage never receives your images, filenames or embedded location data.
