Everyday use cases and practical tips to achieve the optimal balance between image sharpness and file size:
Convert your photos to WebP at 75–80% quality. This achieves up to 70% reduction in bandwidth consumption with imperceptible visual difference.
For icons and UI badges, use WebP or PNG format to preserve sharp vector-like boundaries and crisp alpha transparent backgrounds.
Compress heavy JPG or PNG attachments down to under 500 KB at 60–70% quality to avoid email bounce limits and slow download times.
Use 85–90% quality with original pixel dimensions to preserve smooth gradients in skies, shadows, and skin tones for client showcases.
