Compress HEIC Images for Print

Print-ready images require higher resolution than web images. At 300 DPI, images must be much larger in pixel dimensions to produce sharp, professional-quality physical prints. High Efficiency Image Format — the default photo format on iPhones and modern Apple devices. Excellent compression. Use ImageSmith to compress your HEIC images to the ideal file size for Print — target under 50,000KB for optimal performance. Processing is fully browser-based — no server uploads, no privacy risk.
