HEIC Compressor

Use our free online HEIC compressor to reduce HEIC file size for iPhone photos, form uploads, sharing, and storage. HEIC is already efficient, but compression is still useful when you need to meet a target-size requirement for portals, email, or mobile workflows.

How to Compress HEIC Files Online

HEIC is Apple's default photo format since iOS 11. It is already highly compressed, but our tool can reduce file size further for sharing and uploading.

Upload HEIC Photos

Select HEIC files from your iPhone, iPad, or Mac photo library. You can also AirDrop files to your computer first. Batch upload up to 50 photos at once.

Choose Target Size

HEIC already uses efficient H.265 encoding, so aggressive targets may introduce visible artifacts. We recommend moderate compression — 100 KB to 500 KB typically works well for iPhone photos.

Download Compressed Files

Download your optimized HEIC photos individually or as a ZIP. If you need broader compatibility, consider converting to JPG after compression using our image converter.

Why Choose Our HEIC Compressor

H.265 Encoding

HEIC uses the same H.265 (HEVC) codec found in 4K video, delivering roughly 50% smaller files than JPEG at equivalent visual quality.

Apple Ecosystem Native

Every iPhone since the iPhone 7 shoots HEIC by default. macOS, iPadOS, and iCloud Photo Library all use HEIC natively, saving significant storage space.

Container Format

HEIF is a container that can hold multiple images, depth maps, Live Photo sequences, and HDR data. Our compressor targets the primary image within the container.

Cross-Platform Sharing

Compress HEIC files for smaller size, then convert to JPG for universal compatibility. Our two-step workflow gives you the smallest file in a format everyone can open.

iPhone Storage Saver

Batch-compress your entire camera roll to smaller HEIC files to free 30-50% of photo storage without switching away from Apple's native format.

Web Upload Ready

Most web forms do not accept HEIC. Compress to reduce size, then convert to JPG or PNG before uploading for a universally accepted format at the smallest possible size.

The compression physics

How HEIC compression works at this target

HEIC uses HEVC/H.265 intra-frame encoding — the same codec that runs 4K video on Apple devices. It starts roughly 2× more space-efficient than JPG at equivalent visual quality, which means aggressive size targets (under 200 KB) are physically harder to hit than they would be for a JPG. Our compressor tunes HEIC's quality parameter downward and, where necessary, reduces the tiled-encoding grid; the format degrades more gracefully than JPG at low quality (fewer blocky artefacts) but shows visible noise in shadow areas of low-light photos.

Real portals mapped to size targets

Which target size to pick for HEIC

Different portals cap HEIC uploads at different sizes. Pick the target that matches where you’re uploading rather than shrinking blindly — over-compressing wastes visible quality, under-compressing gets rejected.

50KB

Email preview inline images

Compressing a HEIC to 50 KB is aggressive — the format is already 2× more space-efficient than JPG, so you're asking for the equivalent of a 100 KB JPG.

100KB

Instant-message-safe iPhone photos

A standard iPhone HEIC photo is 1.2-2 MB; compressing to 100 KB shrinks it by ~15×.

150KB

Email attachment sweet spot

Corporate mail servers commonly enforce a 20-25 MB total-message cap; at 150 KB per HEIC you can attach 100+ photos in one email without hitting the cap or triggering "large attachment" warnings.

200KB

iPhone-to-Aadhaar/passport uploads

Indian passport, Aadhaar and PAN portals cap uploads at 200 KB but expect JPG rather than HEIC.

500KB

Social media & messaging (high-quality)

At 500 KB, a HEIC photo retains near-source quality for Instagram Stories, Snapchat, and iMessage forwarding — 500 KB HEIC ≈ 1 MB JPG in perceived quality.

1MB

iCloud photo library optimisation

The "Optimise iPhone Storage" mode caches HEIC photos at ~1 MB locally while keeping the full-res version in iCloud.

2MB

Archive-quality for Apple ecosystem

At 2 MB, a HEIC photo is essentially indistinguishable from the original iPhone capture.

HEIC Compressor FAQ

Quick answers about compression targets, upload limits, format behavior, and the best cases for compressing HEIC files.

What is a HEIC compressor?

A HEIC compressor reduces the file size of HEIC images, which are commonly created by iPhones and other Apple devices.

Why do people compress HEIC files?

People usually compress HEIC files to meet form limits, reduce mobile upload size, and make iPhone photos easier to share.

Will compressing HEIC reduce image quality?

It can if the target size is aggressive. Moderate targets often work best because HEIC is already efficient.

Can I compress HEIC to exact sizes like 100KB or 200KB?

Yes. Exact-size HEIC compression is useful when iPhone users need to upload photos under a strict limit.

Should I compress HEIC or convert it first?

If the destination accepts HEIC, compressing it directly is usually simplest. If not, converting it after compression may be the better workflow.

Can I batch compress HEIC files online?

Yes. Batch compression is useful for groups of iPhone photos that all need to meet a submission or sharing limit.

Is online HEIC compression safe to use?

Yes. The compressor uses temporary browser-based processing with automatic cleanup after compression.
