Why Compress an Image to 800KB?
An 800KB target is ideal for high-quality email photo attachments, Squarespace and Wix image uploads (recommended under 1MB for performance), Airbnb listing photos, real estate marketing images, and ecommerce product photos where quality matters. At 800KB and 1920×1080px, JPEG photos retain excellent visual quality — skin tones, fabric texture, and product details remain accurate — while loading in under 1 second on standard broadband.
Reaching 800KB from a modern smartphone photo (5–20MB) or DSLR RAW export (20–50MB) requires quality 80–85. This tool starts at quality 82, which compresses a 12MP smartphone JPEG (4032×3024px) to 400–750KB for most subjects. All compression runs in your browser — no upload required.
