Compress HEIC

Free, private, and instant — your files never leave your device.

HEIC (High Efficiency Image Container) is the default iPhone photo format since iOS 11, using HEVC compression to store images at roughly half the file size of an equivalent JPEG. It is already an efficient format — but if you need to reduce the file size further, or need a universally compatible output, re-encoding to JPEG or WebP at a lower quality setting is the most practical path. JPEG at quality 80 is universally compatible and typically 40–60% smaller than the decoded source; WebP at quality 80 goes further still, producing files 25–34% smaller than the JPEG equivalent with full browser support. The conversion and compression happen entirely in your browser — your iPhone photos never leave your device.

When you’d want to compress

  • Reducing iPhone photo file sizes before emailing, texting, or sharing on a limited-data connection
  • Hitting a file-size limit on a platform that does not accept HEIC
  • Batch-converting a folder of HEIC photos to a smaller, universally compatible format
  • Preparing iPhone photos for a website or CMS that needs compact web-ready images

What to watch for

EXIF metadata — GPS location, capture date, and camera settings — is not preserved in the output. If you need to keep this data, use a tool that explicitly supports EXIF transfer.
HEIC uses HEVC compression, which is very efficient. The output JPEG or WebP will typically be larger than the original HEIC — you are trading compression efficiency for compatibility and controllable quality.

How to Use

  1. 1

    Drop your HEIC or HEIF files onto the upload area or click to browse.

  2. 2

    Select the output format: JPEG for universal compatibility, WebP for smaller files in modern browsers.

  3. 3

    Set the quality slider. Quality 80–85 is a good starting point for most iPhone photos.

  4. 4

    Download the compressed output — your photos never leave your browser.

Frequently Asked Questions

How much can I reduce the file size of a HEIC photo?

HEIC is already compact, so the comparison depends on the output format. Re-encoding to JPEG at quality 80 typically produces a file of similar size or slightly larger than the original HEIC — HEIC's HEVC compression is very efficient. The value is compatibility, not aggressive size reduction. WebP at quality 80 is usually closest in size to the original HEIC.

What format should I compress HEIC to?

JPEG if you need the result to open everywhere — email clients, older apps, print services, all devices. WebP if the image will be used on a website and modern browser support is acceptable (all major browsers since 2020). PNG if you need lossless output for editing, at the cost of a much larger file.

Are my iPhone photos private?

Yes. All HEIC decoding and re-encoding runs entirely in your browser. Your photos are never uploaded to any server — they are processed locally on your device using JavaScript and the browser's built-in capabilities.
