Everything runs on-device in your browser, so files are never uploaded and processing starts immediately.
For best output quality, keep source images close to their target display size and avoid repeated re-encoding cycles.
If file size matters, test WEBP output and lower quality gradually until text and edges remain visually clean.
This workflow is useful for social posts, blog uploads, CMS media libraries, and messaging attachments.
