AVCHD to TIFF Converter

AVCHD to TIFF Converter

AVCHD is the HD camcorder recording format Sony and Panasonic introduced in 2006 — H.264/MPEG-4 AVC video multiplexed into an MPEG-2 transport stream and written to the card as .MTS files. TIFF is a much older still-image container, created at Aldus in 1986 for desktop publishing and frozen at revision 6.0 since 1992, which is precisely why archives, print shops, and scientific workflows still standardise on it. This tool decodes a single frame out of the camcorder video and writes it as a TIFF still — one picture, not the moving clip.

How to Convert AVCHD to TIFF

1. Upload Your AVCHD Stream File: Drag the individual .MTS or .M2TS clip onto the page, or click "+ Add Files" to browse into the camera's STREAM folder. Several clips can be queued with the same settings.
2. Pick the Frame Under Frame Selection: Specific Frame is already selected and Time (seconds) starts at 0, the first frame of the clip. Type the timestamp you actually want — 4.5 grabs the frame at four and a half seconds — or switch to Multiple Screenshots to sample frames across the whole recording.
3. Set Compression Type and Extension (Optional): Open Compression Type and change it from its JPEG starting value to LZW or Deflate for a lossless still. Use File extension to write .tif instead of .tiff, and Image resolution to scale the frame down.
4. Convert and Download: Click Convert and save the TIFF. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.

Compression Type: the Setting That Decides Lossless

The Compression Type dropdown starts on JPEG, and JPEG compression inside a TIFF is lossy — it re-compresses the frame and discards detail on the way in. For anything archival or print-bound, change it before you convert.

Frequently Asked Questions

Does this convert the whole AVCHD video to TIFF, or just one frame?

Just one frame. The decoder reads the H.264 video inside your clip, takes the single frame sitting at the timestamp you set under Frame Selection, and writes that as a static TIFF; the motion is discarded. Choosing Multiple Screenshots samples several moments across the clip, but each one arrives as its own separate TIFF rather than as a single multi-page file. If you want the moving footage in a modern container, use AVCHD to MP4.

Which compression should I pick for an archival still?

LZW or Deflate. Both are lossless, both are defined for TIFF 6.0, and both keep the saved pixels identical to what the video decoder produced. LZW has the broadest reader support and is the conservative choice for anything going into a long-term archive; Deflate typically writes a slightly smaller file on natural-image content. Pick None only if some legacy application refuses every compressed TIFF you feed it.

Is the TIFF really lossless if the AVCHD source was already compressed?

The TIFF adds no further loss, but it cannot undo the loss that already happened. AVCHD records lossy H.264, so the frame the decoder reconstructs is your ceiling — a lossless Compression Type preserves those exact pixels and nothing more. Think of TIFF here as a faithful, re-editable wrapper around whatever the camcorder's codec produced. Leave the dropdown on its JPEG starting value and you stack a second lossy pass on top of the first, which is exactly what you do not want for archival work.

Which version of the TIFF specification does this output, and is it still maintained?

The output conforms to TIFF 6.0, published on 3 June 1992 and still the current revision of the format. TIFF was created at Aldus Corporation in 1986; Adobe acquired Aldus in 1994 and has held the specification since. That long stability is a feature rather than neglect — it is why a TIFF written today opens in Photoshop, GIMP, ImageMagick, and essentially any imaging or archival tool, and why memory institutions keep choosing it for masters.

Can I get one multi-page TIFF containing several frames?

Not from this tool. TIFF as a format certainly supports multiple images in one file — that is how multi-page scans and faxes are stored — but Multiple Screenshots here writes each sampled frame as an independent TIFF. If you need them bound into a single multi-page document afterwards, combine them with an imaging tool such as ImageMagick, or assemble them into a PDF.

How big is a single extracted TIFF frame from HD footage?

Larger than most people expect, because AVCHD frames are high definition and lossless TIFF stores every pixel. As a floor, a 1920×1080 frame at 8 bits per channel of true colour is 1920 × 1080 × 3 bytes, or roughly 6.2 MB before any compression is applied. LZW and Deflate bring that down on natural imagery with no quality cost, which is why a lossless compressed scheme beats writing the file uncompressed. If the file must be small, that is what JPEG or AVCHD to JPG is for.

Why won't my browser display the downloaded TIFF?

Because outside Safari, browsers do not render TIFF natively — MDN's image-format guide states that other than Safari, browsers only handle TIFF through special libraries or add-ons, and recommends TIFF as a downloadable format for precision editing and printing rather than for web display. Open the file in an image editor or a desktop viewer instead. If you specifically need an on-screen image, convert to PNG or JPG.

How are my files handled, and how long do you keep them?

Your camcorder clip is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public. If your source carries the raw camera extension rather than an .avchd wrapper, MTS to TIFF and M2TS to TIFF are the tuned routes and behave identically.
