Supports: MP4, M4V
MP4 is the universal video container; TIFF is the professional standard for still images that need to survive editing, printing, and long-term archival. The TIFF 6.0 specification was published by Aldus in 1992 and is now maintained by Adobe — it has stayed compatible across three decades of imaging software, which is exactly why archives, prepress shops, and scientific labs still default to it. Common reasons to pull frames out of an MP4 as TIFF:
If you only need web-ready stills, MP4 to JPG or MP4 to PNG produces much smaller files. Use TIFF when "lossless" is non-negotiable.
| Property | TIFF | JPEG | PNG |
|---|---|---|---|
| Compression | Lossless (LZW / Deflate / PackBits) or lossy (JPEG-in-TIFF) | Always lossy | Always lossless |
| Bit depth per channel | 1, 8, 16, 32 | 8 | 8 or 16 |
| Typical size, 1080p frame | 2–6 MB (LZW) | 200–500 KB | 1–3 MB |
| Re-save degradation | None | Compounds each save | None |
| Color spaces | RGB, CMYK, Lab, grayscale | RGB, CMYK | RGB, grayscale |
| Multi-page in one file | Yes | No | No |
| Max file size (classic) | 4 GB | 4 GB | No practical cap |
| Best for | Print, archival, editing | Web sharing, email | Web with transparency, screenshots |
The 4 GB ceiling is a TIFF-format limitation from its 32-bit offsets; for larger images, software writes BigTIFF (64-bit offsets, files up to ~18 EB). A single 4K frame is nowhere near either cap.
| Type | Lossless? | Typical ratio on photo content | Notes |
|---|---|---|---|
| LZW | Yes | ~30–50% | Default. Best balance of speed and compatibility. Defined in TIFF 5 (1988). |
| Deflate (ZIP) | Yes | ~35–55% | Slightly tighter than LZW, slower to write. Adobe extension (TIFF Supplement 2, 2002). |
| PackBits | Yes | ~0–20% | Fastest. Run-length encoding; barely shrinks photos but is in baseline TIFF — every reader supports it. |
| JPEG (in TIFF) | No | 80–95% | Smallest, but throws away pixel data. Don't use for archival. |
| CCITT Group 4 | Yes | Very high | Black-and-white only (1 bit). Designed for fax / document scans. |
| None | Yes | 0% | Largest output. Use only for legacy software that chokes on compressed TIFF. |
MP4 with H.264 or H.265 uses inter-frame compression — only "I-frames" (keyframes) are encoded as complete images, while "P" and "B" frames store only the differences from neighbouring frames. When you grab an arbitrary moment, the converter reconstructs that frame from a chain of references, which on motion-heavy content can show softer detail than a true keyframe. If sharpness matters, scrub to a moment where the camera is still, or use Multiple Screenshots and pick the cleanest still.
Both are lossless — no quality difference between them. LZW is the historical default and is supported by virtually every TIFF reader (defined in TIFF 5 back in 1988). Deflate (a.k.a. ZIP) usually produces files about 10–20% smaller than LZW on photographic content but is slightly slower to write and is technically an Adobe extension from 2002. Pick LZW if your downstream tools are older or unknown; pick Deflate if you've confirmed your workflow supports it and you want the smallest lossless file.
No — the bytes inside are identical. ".tif" is the legacy 3-character DOS-era convention; ".tiff" is the full name. Some Windows tools historically defaulted to ".tif"; macOS and modern image software accept either. Choose whichever your downstream tool, asset manager, or print workflow expects.
A 1080p (1920×1080) frame at 8-bit-per-channel RGB is roughly 6 MB uncompressed, ~2–4 MB with LZW or Deflate, and ~200–500 KB if you choose the JPEG-in-TIFF option (lossy). A 4K (3840×2160) frame is roughly 4× those numbers. If you set "Multiple Screenshots" and extract 50 frames, plan on a ZIP in the 100–300 MB range for 1080p LZW output.
Yes — set Multiple Screenshots and increase the count. Be aware that a 30 fps, 60-second MP4 contains 1,800 frames, which at 1080p LZW would be roughly 4–7 GB of TIFF data. For full-sequence extraction at that scale, lower the resolution, switch to PackBits (faster encode), or consider MP4 to PNG instead — PNG files are typically 30–50% smaller than TIFF LZW at the same quality.
The pixel dimensions are what determine print size; DPI is just metadata. A 1080p frame (1920×1080 pixels) at 300 DPI prints at 6.4 × 3.6 inches; a 4K frame (3840×2160) at 300 DPI prints at 12.8 × 7.2 inches. For larger prints, either start from higher-resolution source video or accept a lower print DPI (180–240 DPI is typical for posters viewed from a distance).
TIFF supports 1, 8, 16, and 32 bits per channel, but most consumer MP4 footage (8-bit H.264 from phones, action cams, screen recorders) is captured at 8-bit. The output TIFF will preserve whatever bit depth the source delivers — promoting an 8-bit source to 16-bit gains no real information. 10-bit HDR MP4 footage (HEVC Main 10) preserves more tonal range in the TIFF if your decoder and downstream editor both handle 10/16-bit pipelines.
No. TIFF is a still-image format only — it has no concept of audio tracks, subtitles, chapter markers, or duration. Those streams in the MP4 are dropped at extraction time. If you need to keep the audio or chapter data, convert the MP4 separately (for example, extract audio as MP3 or WAV) before pulling stills.
Yes. Open the extracted TIFF in any image editor and re-save with stronger compression (Deflate, or JPEG-in-TIFF if you'll accept lossy), or run it through compress TIFF to drop file size without changing dimensions. If you need a much smaller still and don't need TIFF specifically, exporting to JPEG or WebP cuts size by 5–10×.
