HEIC Compression Tips
Combine with Format Conversion
For maximum compatibility, compress your HEIC photos while converting them to JPG or WebP. This gives you smaller files in a universally supported format.
Quality 80-85 for iPhone Photos
iPhone photos contain a lot of detail. At quality 80-85, compressed photos look identical to originals on phone and laptop screens while being significantly smaller.
Batch Process Vacation Photos
Select all your trip photos at once. Compressing hundreds of HEIC photos in one batch saves hours compared to processing them individually.
100% Private Compression
Unlike online compressors that upload your images to their servers, PhotoFormatLab processes everything locally in your browser. Your files are never transmitted anywhere — they stay on your device.
Safe for personal photos, business documents, and confidential images.
