Optional preparation: 10 images, 10 MB each, 40 MB total, 12 MP per image / 24 MP total before decode, 40 MB output. Preparation applies browser EXIF orientation and downsizes without upscaling. JPEG is lossy and fills transparency white; PNG preserves transparency. Image size uses prepared dimensions as PDF points. No HEIC or OCR; limits are not a total memory guarantee.
