DPX (Digital Picture Exchange) is the SMPTE 268M cinema standard for film scanning and VFX, encoding 10-bit or 16-bit per channel imagery with logarithmic color. DPX is native to professional tools like DaVinci Resolve, Nuke, and Flame. WebP is Google's modern image format offering 25-34% better compression than JPEG and 26% better than PNG, with both lossy and lossless modes and universal browser support.
Converting DPX to WebP produces the most storage-efficient frames from cinema-grade source material. WebP's superior compression is particularly valuable when DPX frames need to be served on the web — production review platforms, portfolio websites, VFX breakdown pages, and streaming service marketing sites all benefit from WebP's fast loading and low bandwidth usage compared to JPEG or PNG alternatives.
Web delivery of cinema content demands efficient compression. WebP delivers 25-34% smaller files than JPEG at equivalent visual quality, which translates to faster page loads on portfolio sites, VFX breakdown galleries, and production review platforms. For a gallery of 50 film stills, WebP saves 30-40% of bandwidth compared to JPEG — meaningful for both hosting costs and viewer experience.
WebP's lossless mode provides an alternative to PNG for frame stills where quality cannot be compromised. Lossless WebP files are 26% smaller than equivalent PNG files, making them the most efficient lossless web format available. For production review platforms where every pixel matters but files need to be web-deliverable, lossless WebP is the optimal choice.
The DPX data is decoded with log-to-linear color space conversion using a Cineon-to-sRGB LUT. The high-bit-depth source is tone-mapped to 8-bit per channel. Sharp or ImageMagick encodes the result as WebP — lossy mode uses VP8 encoding with configurable quality (default 88 for cinema stills), lossless mode uses VP8L. ICC color profile embedding is supported. Full spatial resolution of the DPX frame is maintained unless resizing is requested. Alpha channel transparency is supported in both lossy and lossless modes.
Lossy WebP at quality 88-92 produces cinema frame stills visually indistinguishable from equivalent JPEG quality 95, at 25-30% smaller file sizes. Skin tones, atmospheric effects, and subtle color gradations are preserved well at these settings. Lossless WebP preserves every pixel after the log-to-linear conversion, with smaller files than PNG. The log-to-linear conversion quality — determined by the LUT used — is the primary quality factor, not the WebP encoding itself.

DPX to WebP conversion produces the most bandwidth-efficient web-ready frames from cinema source material. Lossy mode delivers smaller-than-JPEG files with equivalent quality; lossless mode outperforms PNG. WebP is the optimal choice for web delivery of film content.
