How PGM Handles JPG Data
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. JPEG Image may clip extreme values. PGM Grayscale maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the PGM Grayscale format supports it. Format-exclusive metadata fields that have no equivalent in PGM Grayscale are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality JPEG Image input produces an excellent PGM Grayscale output. Since the target format is lossless, output quality matches your input exactly.
Converting between image formats is one of the most common file operations. When moving from JPEG Image to PGM Grayscale, key considerations include color depth preservation, transparency support, and compression artifacts. Since JPEG Image is lossy while PGM Grayscale is lossless, the conversion will perfectly preserve your current image data without further degradation — though it cannot restore details lost during the original JPEG Image compression.
Important: Converting from lossy JPG to lossless PGM does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original JPG encoding cannot be recovered.
