How ebookconvert optimizes images step-by-step

Scan and Analyze Images

ebookconvert scans your manuscript, detects all embedded images, reads resolution and color profiles, and flags large or unsupported formats for optimization.

2

Choose Smart Compression

Apply lossless or perceptual (lossy) compression, downscale oversized images to recommended EPUB/MOBI resolutions, and optionally convert to WebP for smaller file sizes.

3

Embed, Validate, Export

Reinsert optimized images into your ebook, update the manifest and metadata, run a validation check for e-reader compatibility, and export EPUB/MOBI ready for distribution.

Practical tips and a quick checklist for image optimization

Start by identifying images that drive file size—high-resolution photos and large PNGs are common culprits. Use ebookconvert to automatically recommend target resolutions per device.

Keep illustrations at native resolution when detail matters; downscale photographs to match typical e-reader pixel density and use compression profiles to retain perceived quality.

Optimization Checklist

  • Remove unnecessary metadata and color profiles
  • Resize images to 150–300 DPI depending on content type
  • Convert photos to WebP when supported for smaller files
  • Run final EPUB/MOBI validation before publishing
