Compress an HEIC Photo for Upload on iPhone
Check an HEIC file against an upload limit, then create a smaller photo copy locally on iPhone with SendShrink.
When an HEIC photo is too large to upload, check its actual file size against the destination limit before changing it. The free checker can compare HEIC file size even when the browser cannot preview the image. SendShrink then creates a smaller photo copy locally on iPhone while leaving the original unchanged. Confirm whether the destination accepts HEIC or requires another image format.
HEIC size and HEIC compatibility are different problems A destination can reject a file because it is too large, because HEIC is not accepted, or because both rules apply. Read the error message or upload instructions before compressing so you solve the correct problem. The checker works from the saved file size Some browsers cannot display an HEIC preview, but they can still report the file size selected from the device. The checker uses that saved size for PASS or TOO LARGE and does not upload the photo to Kamnevapps. Use a local iPhone workflow for the smaller copy SendShrink processes selected photos on device and creates smaller copies for forms, email, messages, and other uploads. The original remains unchanged, and the final saved result should be checked against the destination requirements before submission.
Workflow steps: Find the destination file-size limit and accepted image formats. Use the free checker to compare the HEIC file with the KB or MB limit. If it is too large, create a smaller copy locally with SendShrink. Check the new file size and format before uploading it.
Common questions: Can the checker read an HEIC file size without previewing it? Yes. File size can be checked even when a browser does not decode an HEIC preview. Why does a website reject HEIC even when the file is small? The website may accept only JPEG, PNG, or another listed format. File-size and file-format rules are separate. Does SendShrink upload HEIC photos to a server? No. Selected photos are processed locally on the iPhone according to the current SendShrink privacy information.
