Private Processing

💡 Compressing to 20KB: What to Expect
Very small target (20KB): Files under 30KB are extremely compact. Only simple graphics, icons, and tiny thumbnails compress well to this size. Photographs will show visible artifacts at this target — consider whether the use case truly requires 20KB, or if 100KB would work.
Best format: WebP is essential at this size — it produces significantly better quality than JPEG at the same file size. Resize to the smallest acceptable dimensions first (e.g., 200×200 for icons, 400×300 for email thumbnails).
Use cases: Email signature images, favicon alternatives, lightweight placeholder thumbnails, and bandwidth-constrained mobile applications where every kilobyte matters.
