Compress HEIC to 1MB

1. Upload your HEIC (up to 50 MB).
2. The compressor automatically targets 1 MB or under.
3. Download the compressed HEIC — virtually identical to the original.

1 MB is generous for HEIC — high-resolution photos and HDR images both fit. iPhone photos compressed to 1 MB HEIC typically retain 95%+ of their original quality while being 2-4x smaller.

1 MB is the target for high-resolution iPhone photos where quality matters most — HDR data, fine detail, and print preview. Modern iPhones produce 2-4 MB HEIC photos; compressing to 1 MB reduces size 50-75% while preserving 95%+ of original quality. This is useful for archival, high-quality email, and any platform that accepts up to 1 MB.

The compressor decodes the HEVC-compressed HEIC image and re-encodes it using libheif at a lower quality setting. If the output exceeds 1 MB, it reduces quality (and if necessary, dimensions) until the target is met. At 1 MB, a HEIC is typically 3000-4000px wide with quality 92-96% — visually identical to the original.

• Archiving high-resolution iPhone photos.
• Preparing HEIC for print preview (medium format).
• High-quality email attachments (under 25 MB).
• Preserving HDR photos with minimal size reduction.
• Reducing iCloud storage without losing visible quality.
• High-quality portfolio delivery.
• Any platform with a 1 MB HEIC limit.

1 MB is very high-quality for HEIC — the photo is visually identical to the original. Expect 3000-4000px wide with quality 92-96%. HDR metadata is often preserved at 1 MB.

• 1 MB is large — not ideal for web performance or email.
• For web use, 100-200 KB is usually sufficient.
• For high-quality email, 200-500 KB is more appropriate.
• HDR preservation is not guaranteed at all quality settings.
• For maximum quality, keep the original HEIC.

• Compressed HEIC opens natively on iOS 11+, iPadOS, macOS High Sierra+.
• Windows 10/11 supports HEIC with the free HEIF Image Extensions.
• Syncs with iCloud Photos.
• Accepted by most CMS platforms (with HEIC support).
• Standard HEIC — no special software needed on Apple devices.

• 1 MB is best for archival and high-quality preservation.
• HDR metadata is often preserved at 1 MB.
• For web use, 100-200 KB is usually sufficient.
• HEIC opens natively on Apple devices.
• Batch-compress up to 50 MB of HEIC files at once.

HEIC is still over 1 MB after compression

Very large originals may need resizing. Try cropping, or use the general HEIC compressor.

File is larger than needed for web

For web use, 100-200 KB is usually sufficient. Use those variants instead.

HDR metadata is lost

At 1 MB, HDR is often preserved. If it's lost, use 'Low' quality in the general HEIC compressor, or keep the original.
