JPEG vs HEIF vs PNG for an Extracted Video Frame
Compare JPEG, HEIF, and PNG for still frames saved from iPhone videos. Choose an export format in Frame Grabber based on file size, compatibility, and quality.

Short answer
Choose JPEG for broad compatibility, HEIF for a smaller file with good quality on modern Apple devices, or PNG when you want lossless export and accept a larger file. None can restore detail missing from the video. Keep the source if you might need another export.
You have found the frame, and the export screen offers three file types. Choose by where the picture is going: a website, your Apple photo library, or an editor. The largest file will not necessarily show more detail.
We make Frame Grabber, which exports all three formats discussed here. The destination and the source image determine which one makes sense.
Choose by the destination
| Format | Main reason to choose it | Check first |
|---|---|---|
| JPEG | Broad compatibility | Quality setting and visible artifacts |
| HEIF | Efficient storage | Whether the recipient accepts it |
| PNG | Lossless image compression | File size and upload limits |
JPEG for everyday sharing
JPEG is the safest choice when the image will move between websites, messages, documents, and non-Apple devices.
Its compression can introduce small artifacts, especially after repeated saves. A higher quality setting keeps more detail at the cost of a larger file.
HEIF for efficient storage
HEIF can retain similar visual quality to JPEG in a smaller file. iPhone, iPad, and Mac handle it well.
Check the destination before relying on HEIF. Some upload forms, older editors, and third-party services still expect JPEG or PNG.
Apple’s HEIF guidance explains compatibility and conversion on Apple devices. Test the app or website that will receive the image before exporting a large set.
PNG for a lossless export
The PNG specification defines lossless image compression. PNG export avoids adding another lossy compression step. It is useful when you plan to edit the image repeatedly or need predictable pixel values.
The file may be much larger, and the source frame still contains the compression and blur of the original video. Lossless export is not the same as a lossless source.
Choose the format before you save
Frame Grabber exports JPEG, HEIF, and PNG. JPEG and HEIF include adjustable quality controls.
