Compress HEIC online
Reduce HEIC file size while keeping the output as HEIC. FormatGo works as an online HEIC compressor for iPhone photos and other HEIC images that need a smaller file without converting to JPG, PNG, or WebP.
For multi-image HEIC files, the current version compresses the primary image.
Why use a HEIC compressor
HEIC is already efficient, but iPhone photos and high-resolution images can still be too large for uploads, storage, forms, email, or fast sharing. This page focuses on reducing HEIC file size while keeping the file in HEIC format.
Adjust the HEIC compression quality to balance smaller file size with image detail.
Compress HEIC files without changing them into JPG, PNG, or WebP when you need to keep the original format family.
Use the compressor for common iPhone HEIC images when the file is larger than your upload or sharing workflow allows.
Built for practical HEIC compression
The compressor is designed for the simple job behind the main search intent: upload a HEIC file, choose the compression level, and download a smaller HEIC result.
Use a lower quality value for stronger compression or a higher value when preserving detail matters more.
Reduce HEIC file size before sending photos through forms, storage tools, email, or services with upload limits.
The output remains a HEIC file, so this page is for compression rather than format conversion.
HEIC compression FAQ
Quick answers about compressing HEIC files, reducing file size, quality settings, and what the current compressor supports.
Upload your HEIC or HEIF file, choose a compression quality level, start the task, and download the smaller HEIC result when it is ready.
Yes. This compressor is designed to output a smaller HEIC file instead of converting the file to JPG, PNG, or WebP.
Use a lower compression quality value when you need a smaller file. A lower value usually reduces file size more, while a higher value keeps more visual detail.
The quality setting controls the HEIC encoder quality. Lower values usually make smaller files, while higher values keep more image detail.
The default quality is a practical starting point. If the file is still too large, lower the value; if the image loses too much detail, raise the value and compress again.
V1 compresses the primary image from the HEIC container. Multi-image preservation can be added in a later version.
Yes. FormatGo is designed for common iPhone HEIC photos and other HEIC files that can be decoded by the server pipeline.
Yes. HEIC is already an efficient image format, but large camera photos can still be compressed further when you need a smaller file for upload, transfer, or storage.
Use HEIC compression when you want a smaller file but still need HEIC output. Use HEIC to JPG when compatibility with more apps, websites, or devices matters more than keeping HEIC.
