Client-Side JPEG Encoding & Alpha Flattening
Joint Photographic Experts Group (JPEG / JPG) remains the gold standard format for digital photography, web publishing, and document upload portals. However, PNG and WebP files often contain transparent alpha channels, which JPEG does not support. Safeshot automatically handles transparent pixel flattening during client-side encoding.
When you export a transparent PNG or WebP file to JPEG using Safeshot, our canvas engine draws a clean solid white background layer underneath your artwork before running Discrete Cosine Transform (DCT) quantization. This prevents dark or distorted background boxes on final JPEG image exports while maintaining 100% data privacy inside your browser sandbox.
