Calculation Methodology & Formula
Decodes bitmap rasters into an HTML5 Canvas context and re-encodes pixel streams through browser-native encoders. Alpha-channel transparency is automatically composited over white for JPEG outputs.
OutputBlob = Canvas.toBlob(ImageRaster, TargetMime, Quality)Worked Example: PNG Transparency to Compact WebP Conversion
Convert a 1.8 MB transparent PNG logo into a modern, lightweight WebP image.
WebP retains full 8-bit alpha transparency while reducing file size by up to 80%.
Technical Constraints & Limitations
- Converting transparent PNGs to JPEG composites transparent pixels against a solid background because JPEG lacks an alpha channel.
- True PDF conversion requires vector document container generation; this tool converts raster web formats (PNG, JPG, WebP) and does not output fake PDF wrappers.
