Quick fact about HEIC

500 KB is generous for HEIC — high-resolution iPhone photos and print preview both fit well. iPhone HEIC photos compressed to 500 KB typically retain 90%+ of their original quality while being 3-5x smaller.

Why compress HEIC?

500 KB is a good target for high-resolution iPhone photos that still need to be a manageable size. Modern iPhones produce 2-4 MB HEIC photos — compressing to 500 KB reduces storage use by 75-90% while keeping the photo sharp on screens and acceptable for small prints.

How the conversion works

The compressor decodes the HEVC-compressed HEIC image and re-encodes it using libheif at a lower quality setting. If the output exceeds 500 KB, it reduces quality (and if necessary, dimensions) until the target is met. At 500 KB, a HEIC is typically 2000-3000px wide with quality 85-92%.

When to compress HEIC

Quality considerations

500 KB is high-quality for HEIC — iPhone photos look essentially identical to the original on screens. Expect 2000-3000px wide with quality 85-92%. Great for archival, portfolio, and small-format print.

File is larger than needed for web
For web use, 100-200 KB is usually sufficient. Use those variants instead.
