Supports: TIFF, TIF
.tif / .tiff images. Batch is supported — name your files in shot order (frame_0001.tif, frame_0002.tif,...) so the sequence assembles correctly.TIFF (Tagged Image File Format, Revision 6.0 published by Aldus in 1992 and now an Adobe-stewarded spec) is the standard container for high-bit-depth, lossless still images — photographers, scanners, GIS workflows, and microscopy all produce TIFFs. Matroska (MKV) is an open, extensible container that wraps essentially any video codec the FFmpeg ecosystem supports. Converting a TIFF sequence into MKV turns a folder of stills into a single playable file you can scrub, share, or hand to a video editor.
| Property | TIFF | MKV (Matroska) |
|---|---|---|
| Type | Raster still image (single or multi-page) | Multimedia container |
| First released | 1986 (TIFF 3.0); Revision 6.0 in 1992 | 2002 |
| Steward | Adobe (post-1994 acquisition of Aldus) | Matroska / CELLAR (IETF) |
| Stores motion | No (multi-page TIFF is still images) | Yes — any number of video, audio, and subtitle tracks |
| Typical bit depth | 1, 8, 16, or 32 bits per channel | Depends on inner codec (H.264 8-10 bit, H.265 8-12 bit, FFV1 up to 16 bit) |
| Compression | Optional: LZW, ZIP/Deflate, PackBits, JPEG, none | Codec-level (H.264, H.265, VP9, AV1, FFV1, ProRes wrapper, etc.) |
| Browser playback | Limited (Safari/Firefox via plug-ins; not in Chrome by default) | Limited natively; universal in VLC, MPV, Plex, and editors |
| Lossless option | Native (PackBits, LZW, ZIP, or uncompressed) | Native via FFV1 codec |
| Typical use | Photography, scanning, GIS, archival stills | Movies, archival masters, image sequences, slideshows |
| MIME | image/tiff | video/x-matroska |
| Codec | Bit depth | Best for | Trade-off |
|---|---|---|---|
| H.264 (AVC) | 8-bit (10-bit Hi10P) | Maximum playback compatibility — every browser, every TV | Larger files than HEVC/AV1 at the same quality |
| H.265 (HEVC) | 8/10/12-bit | ~50% smaller than H.264 at the same visual quality | Patent licensing; not universal in browsers |
| VP9 | 8/10/12-bit | Open, royalty-free, plays in Chrome/Firefox/Edge | Slower encode than H.264 |
| AV1 | 8/10/12-bit | Best compression (≈30% smaller than HEVC); royalty-free | Slowest encode; newer hardware decode |
| FFV1 (v3) | up to 16-bit | Lossless archival (Library of Congress Preferred Format in MKV) | Files much larger than lossy codecs |
| MJPEG | 8-bit | Frame-accurate intra-only editing | No inter-frame compression — large files |
| MPEG-4 / DivX / Xvid | 8-bit | Legacy device targets | Outclassed by H.264 for the same use case |
MKV's Matroska container is far more permissive about which codecs it accepts. MP4 (ISO BMFF) is officially specified for a narrow codec set — H.264, H.265, AV1, AAC, MP3, and a handful of others. MKV will happily wrap FFV1 (the archival lossless codec the Library of Congress upgraded to Preferred in December 2023), MJPEG, ProRes, and codecs MP4 won't touch. MKV also supports multiple subtitle tracks, chapters, and attachments natively. If you only need YouTube/iPhone playback, MP4 is fine; if you need archival, multi-track, or unusual codecs, MKV is the right container.
It depends on the source. VFX and animation TIFFs are typically rendered at 24, 25, 29.97, or 30 fps — pick "Image Duration" of 1/24, 1/25, 1/30 second to match. Microscopy or time-lapse sequences can use any rate (1 fps and up) depending on how dense your sampling is. Slideshow-style decks of photos look natural at 2-5 seconds per image. The xconvert "Image Duration" control in Advanced Options exposes both image-sequence rates (down to 1/60 sec per frame) and slideshow rates (1-10 seconds per frame).
It depends on the codec you pick. H.264 8-bit and H.265 8-bit truncate to 8 bits per channel, so banding can appear in skies and gradients that were smooth in your 16-bit TIFF master. H.265 10-bit, VP9 10/12-bit, AV1 10-bit, and FFV1 all preserve more of the original depth. For archival or grading work, choose FFV1 (lossless) or one of the 10/12-bit lossy codecs; for streaming/sharing, H.264 or H.265 at "Very High" quality is fine.
Two likely causes. First, if you picked FFV1 it's lossless — expect roughly 30-70% of uncompressed size, which is still huge versus H.264. Second, if your Image Duration is short (1/24 sec) but your TIFFs are very high resolution (e.g., 4K or 6K scans), each second of MKV holds 24 frames of fine detail; encoders need bitrate to keep that quality. Lower the resolution preset, raise the Image Duration, or switch from FFV1/MJPEG to H.265 or AV1 to shrink the file. See compress MKV if you need to shrink the result further.
This converter is image-only — the resulting MKV is silent. If you need a soundtrack, generate the silent MKV here, then mux audio in with a desktop editor (DaVinci Resolve, Shotcut, kdenlive) or via FFmpeg (ffmpeg -i video.mkv -i audio.flac -c copy out.mkv). MKV happily accepts FLAC, AAC, Opus, and Vorbis audio tracks alongside the video.
Yes. The converter resizes each frame to a single output resolution (either "Keep original" of the first frame, a Resolution Preset like 1080p/4K, or your Width × Height). Frames whose aspect ratio doesn't match the output are letter- or pillar-boxed using your chosen Background Color. To avoid that, crop or resize your TIFFs to a uniform size before upload — compress TIFF can also batch-resize them.
A multi-page TIFF (where one .tif file contains several images, common in fax and document scanning) is read as a single image by most converters — the additional pages are dropped. For true image-sequence conversion, export each page as a separate numbered TIFF first, then upload the folder. If you have a multi-page TIFF and want a PDF instead, merge image to PDF preserves every page.
Yes. Use MKV to TIFF to extract each video frame as a numbered TIFF, which is the typical VFX round-trip: render TIFFs → MKV proxy → review → re-extract TIFFs for final colour grade. The TIFF to MP4 and TIFF to WebM routes exist if you need a different container, and PNG to MKV covers the lossless-still alternative when your source is PNG instead of TIFF.
