AVCHD to HEIC Converter

AVCHD to HEIC Converter

This tool takes a single frame out of a camcorder clip and saves it as a HEIC image. AVCHD is the high-definition recording format Sony and Panasonic introduced in 2006 — H.264/AVC video multiplexed into an MPEG transport stream, written to the card as .MTS and usually renamed .m2ts after import. HEIC is the other end of the timeline: a still image coded with HEVC inside the HEIF container standardised as ISO/IEC 23008-12, and the format iPhones have written by default since iOS 11 in 2017. The reference tables below cover what each format is before the steps show how to pick your frame.

What You Get, and the Interlacing Catch

The output is one still image decoded from the timestamp you choose, encoded as HEVC and wrapped as HEIC. Nothing else in the clip is touched, and the video is not re-encoded. Image resolution starts on Keep original, so the still carries the recording's native frame size — 1920x1080 for most modern AVCHD footage, 1440x1080 on older or lower-bitrate modes, where the anamorphic pixels are stretched to a 16:9 display shape.

The one artefact worth planning around is interlacing. AVCHD's 60i and 50i modes build each frame from two fields captured a fraction of a second apart, so a frame grabbed during fast motion can show fine horizontal comb lines along moving edges. It is a property of the recording, not of the conversion — the fix is to pick a timestamp where your subject is comparatively still, then convert again.

How to Convert AVCHD to HEIC

1. Upload Your AVCHD File: Drag and drop the .mts, .m2ts, or .avchd clip onto the page or click "+ Add Files". No software to install.
2. Set the Time (seconds) Under Frame Selection: With Specific Frame selected, type the moment you want — 2.100 grabs two seconds and 100 milliseconds in. Switch to Multiple Screenshots instead to sample frames across the whole clip at a chosen interval.
3. Pick Quality Preset and Image Resolution: Leave Quality Preset on "Very High (Recommended)" for a near-transparent still, and Image resolution on Keep original for the camera's full frame size; choose a Preset Resolution or an exact Width x Height when you want something smaller.
4. Convert and Download: Click Convert and download the HEIC. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours later. No sign-up, no watermark.

Frequently Asked Questions

What exactly is a HEIC file?

An image stored in the HEIF container defined by ISO/IEC 23008-12, with the picture itself coded using HEVC. That combination is what Apple adopted for the iPhone camera in iOS 11, which is why HEIC is everywhere on Apple devices and comparatively rare elsewhere. The container can also hold image sequences, depth maps, and auxiliary layers, though a frame grab like this uses a single still image item.

Which frame does the tool grab if I change nothing?

The very first one. We checked this page's own option data: Frame Selection starts on Specific Frame with the time set to 0 seconds, so a conversion launched without adjusting anything returns the frame at the start of the clip. Type a value into Time (seconds) — decimals are accepted — to land anywhere else in the recording.

Why is my still striped or combed along moving edges?

Because the clip was recorded interlaced. AVCHD supports 60i and 50i modes in which each frame is woven from two fields captured moments apart, so anything moving quickly does not line up between them and appears as fine horizontal teeth. Nudge the Time (seconds) value a fraction of a second either way to land on a calmer frame; static subjects show no combing at all.

What resolution will the extracted still be?

Whatever the recording holds, as long as Image resolution stays on Keep original. Most AVCHD footage is 1920x1080; older and lower-bitrate modes use 1440x1080 with non-square pixels, and 1280x720 appears on some camcorders. If you want something smaller for the web, pick a Preset Resolution or set an exact Width x Height rather than shrinking the file afterwards.

Will the HEIC open on Windows or in a browser?

Not reliably. Browser support is essentially Safari 17 and later — roughly 15% of tracked traffic — while Chrome, Firefox, and Edge do not decode HEIC at all. On Windows the Photos app needs Microsoft's HEVC extension installed first. If the still is going anywhere outside the Apple ecosystem, AVCHD to JPG or AVCHD to PNG saves a lot of explaining.

Can I get several stills from one clip?

Yes — switch Frame Selection from Specific Frame to Multiple Screenshots and choose a capture rate, from one frame every ten seconds down to ten frames a second. That is the right mode for contact sheets, for finding the one usable frame in a fast sequence, or for building a rough storyboard from an event recording.

Does extracting a frame re-encode the whole video?

No. The clip is decoded only as far as your chosen timestamp, and that single frame is encoded as a HEIC image. The source file is untouched and nothing else in the recording is re-compressed, which is why a frame grab from a long clip is quick compared with a full video conversion.

HEIC or JPG for a camcorder still?

HEIC when the destination is an iPhone, iPad, or Mac and you want the smaller file at equal quality; JPG when anyone else has to open it. HEVC-coded stills genuinely beat JPEG on size for the same visual quality, but that advantage is worth little if the recipient's software shows a grey box. For a still destined for email, a document, or a website, JPG remains the safe answer.

My clip is named .m2ts, not .avchd — is that a problem?

No, they are the same recordings. .MTS is what the camcorder writes to the memory card, .m2ts is the usual name once the file is copied to a computer, and .avchd describes footage from the same folder structure. Upload whichever you have; MTS to HEIC is the same extraction under the camera's own naming.

How are my uploaded files handled?

They are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion, along with the images they produced. Nothing is shared or made public, there is no watermark, and no account is required.
