Supports: MKV
Pull a pixel-exact still out of an MKV (Matroska) video and save it as a TIF (Tagged Image File Format) image — the lossless, high-bit-depth raster that print, archival, scientific, and forensic workflows standardize on. Grab one frame at an exact timestamp, or capture a whole sequence of separate TIF files across the clip. Every frame is reconstructed straight from the decoded video, so nothing is re-compressed the way a JPG screenshot would be. .tif and .tiff are the same format and produce identical files here; pick whichever extension your software expects.
.mkv onto the page or click "+ Add Files". You can queue several videos and convert them with the same settings.| Property | TIF / TIFF | PNG | JPG |
|---|---|---|---|
| Compression | Lossless (LZW, Deflate, ZSTD, PackBits) or none | Lossless (Deflate) | Lossy |
| Pixel-exact to source frame | Yes | Yes | No — recompressed |
| Bit depth | 8 or 16 bit per channel | 8 or 16 bit per channel | 8 bit per channel |
| Color models | RGB, CMYK, grayscale, more | RGB, grayscale | RGB, grayscale |
| Embedded metadata | EXIF, IPTC, XMP, ICC profiles | Limited | EXIF |
| Typical file size | Largest | Medium | Smallest |
| Best for | Archival, print, editing, forensics | Web-friendly lossless | Quick preview / sharing |
If you want the same lossless quality in a smaller, web-friendly file, convert MKV to PNG instead. Need the identical output under the .tiff extension, or want the full-resolution archival write-up? See Convert MKV to TIFF. To pull frames from a different container, use the video-to-TIF converter, which accepts MP4, MOV, AVI, WebM, and more.
Yes. The frame is decoded from the video and written to TIF without lossy re-compression, so it is pixel-for-pixel identical to what the MKV decodes to at that moment. A JPG screenshot, by contrast, re-encodes the frame with lossy compression and softens fine detail. TIF is why print, archival, and forensic workflows prefer it over a screenshot for stills that will be edited or examined.
Specific Frame extracts a single still at the timestamp you enter in the Time (seconds) field, producing one TIF. Multiple Screenshots walks the whole clip and saves a separate TIF for each frame at the Capture Rate you choose — for example, "1 second per frame" yields roughly one image per second of video. The higher the capture rate, the more individual TIF files you get back.
Because TIF stores each frame as a full, lossless (or uncompressed) raster, while the MKV holds the whole video using inter-frame video compression that only records what changes between frames. A single 1080p frame can be several megabytes as TIF, and a long sequence at a high capture rate adds up quickly. If size matters, choose the LZW, Deflate, or ZSTD Compression Type — all still lossless — or export to PNG instead.
LZW is the most widely supported and opens in virtually every image editor, so it is the safe default for sharing. Deflate (zip) and ZSTD usually produce smaller lossless files but need a reasonably modern reader. Choose None only when a downstream tool requires fully uncompressed raster data. All of these keep the frame lossless — they only change file size and compatibility, not image quality.
Use 8-bit for ordinary footage and general editing; choose 16-bit when you need maximum precision for heavy color grading or scientific analysis. In our testing, a standard 8-bit 1080p frame is plenty for print and web, while 16-bit roughly doubles the file size for headroom most projects do not need. Note that most consumer MKVs are 8-bit; 16-bit output cannot invent detail the source never recorded, though it does preserve everything a 10-bit or HDR MKV provides without further clipping.
Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion finishes. There is no sign-up, no watermark, and your files are never shared or made public. MKV (Matroska) is an open, royalty-free container — formally published as RFC 9559 in October 2024 — that can hold almost any codec, commonly H.264, H.265/HEVC, VP9, or AV1, and all of those decode here before the frame is written to TIF.
