MPG to HEIF Converter

MPG to HEIF Converter

An MPG is a video file (MPEG-1, the format standardized in 1993); HEIF is a modern still-image format. This tool does not turn a movie into a video — it decodes one frame from your MPG at the moment you choose and saves it as a single HEIF picture. HEIF (High Efficiency Image File Format) stores that frame with HEVC compression, so the file is typically much smaller than the equivalent JPEG at similar quality. The trade-off is reach: HEIF opens natively only in the Apple ecosystem and recent Safari, so if you need a still that opens everywhere, grab it as JPG or PNG instead. By default the frame is taken at time 0 — the opening frame — and you can set any timestamp to capture a different moment.

How to Convert MPG to HEIF

1. Upload Your MPG File: Drag and drop your video onto the page or click "+ Add Files" to pick it from your device. Both .mpg and .mpeg files are accepted, and you can queue several at once.
2. Choose the Frame: In "Frame Selection", keep "Specific Frame" and set "Time (seconds)" to the exact moment you want (for example, 0 for the opening frame or 2.5 for 2.5 seconds in), or switch to "Multiple Screenshots" to export several frames across the clip as separate files.
3. Set Quality and Size (Optional): Pick a "Quality Preset" (Very High is the default), and optionally shrink the still with "Resolution Percentage", a "Preset Resolutions" size, "Width", "Height", or a "Specific file size".
4. Convert and Download: Click "Convert" and download your HEIF. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

Frequently Asked Questions

Does this turn my MPG video into a HEIF video or extract a single frame?

It extracts a single frame as a still image. The output is one picture, not a video or an animation. By default the grab is taken at time 0, so you get the opening frame; set "Time (seconds)" under "Frame Selection" to capture any other moment. If you want a sequence of stills, switch to "Multiple Screenshots", which samples several frames across the clip and returns each as its own HEIF. To turn an MPG into an animated image instead, use MPG to GIF.

Why won't my HEIF file open on Windows or in Chrome?

Because HEIF support is narrow. Native HEIF decoding ships in Safari 17 and later on macOS and iOS, but Chrome, Firefox, and Edge do not display HEIF, and Windows needs the HEIF Image Extensions (and the HEVC codec) installed from the Microsoft Store before Photos or File Explorer will preview it. Per caniuse, only about 14% of browsers worldwide support HEIF at all. If you need a still that opens anywhere without extra software, convert to JPG with our MPG to JPG converter or to PNG with MPG to PNG instead.

What is the difference between HEIF and HEIC?

They are the same underlying format with different extensions. HEIF (.heif) is the general High Efficiency Image File Format defined by ISO/IEC 23008-12, while HEIC (.heic) names the specific case where the image inside is encoded with HEVC — the variant Apple writes from the iPhone camera. In practice the files are structurally the same family; the .heic extension just signals an HEVC payload. If you specifically want the .heic extension, use our MPG to HEIC converter.

How do I grab a specific moment instead of the first frame?

Leave "Specific Frame" selected in "Frame Selection" and type the timestamp into "Time (seconds)" — for instance 8 for eight seconds in, or 8.5 for halfway through that second. The decoder seeks to that point in the MPG and writes exactly that frame as your HEIF, so you are not stuck with whatever the opening frame happens to be.

Will converting to HEIF lose quality?

Some, but HEIF is efficient about it. HEIF stores the frame with HEVC compression, which generally preserves more detail at a given file size than JPEG. The bigger limit here is the source: MPG (MPEG-1) clips are themselves lossy and usually standard-definition — often around 352x240 (NTSC) or 352x288 (PAL) for Video CD content — so the frame already carries pre-existing compression artifacts before HEIF is applied, and HEIF cannot add detail that was never recorded. Keep "Quality Preset" at Very High to minimize added artifacts. For a pixel-exact frame with no further lossy compression, grab it as a lossless PNG with our MPG to PNG converter.

Does the output include any audio from the MPG?

No. HEIF is an image format and holds no audio. Only the visual content of the selected frame is saved; the MPG's audio track is discarded during conversion.

What happens to my files after conversion?

Your MPG is uploaded over an encrypted connection, processed on our servers, and both the upload and the generated HEIF are deleted automatically a few hours after conversion. There is no account, no sign-up, and no watermark, and files are never shared or made public. In our testing, a 352x288 PAL MPG frame produced a sharp HEIF still in the 15-40 KB range at the Very High preset, noticeably smaller than the equivalent JPEG of the same frame.
