Initializing... drag & drop files here
Supports: TIFF, TIF
.tiff or .tif files, or click "+ Add Files" to select them. Batch upload is supported — drop a whole sequence and the converter assembles them in alphanumeric order, which matches how cameras and scientific instruments name frames (img_0001.tif, img_0002.tif...).1/24 second to play TIFFs as a true 24 fps timelapse, or stretch it to 10 seconds for a slow gallery walkthrough..avi downloads when ready. No watermark, no sign-up, and uploads are deleted from the server after processing.TIFF is a 32-bit Tagged Image File Format originally developed by Aldus (now Adobe) and capped at 4 GB per file — fine for one master scan, but unwieldy when you have hundreds of frames from a microscope time-lapse, a DSLR image sequence, or a flatbed batch scan. Bundling those frames into a single XviD-encoded AVI gives you a playable timeline, dramatically smaller storage, and a file format that DVD players, hardware media boxes, and Windows machines from the 2000s era will recognize on sight.
| Property | TIFF (.tiff / .tif) |
XviD AVI (.avi) |
|---|---|---|
| Type | Still raster image (one or more pages) | Video container + codec |
| Container / codec | TIFF baseline + extensions (LZW, ZIP, JPEG, ZSTD compression) | RIFF/AVI container with Xvid (MPEG-4 Part 2 ASP) video |
| Specification owner | Adobe (TIFF 6.0, 1992) | Microsoft AVI (Nov 1992) + Xvid open-source project |
| Max file size | 4 GB (classic TIFF); 18,000 PB with BigTIFF 64-bit offsets | ~4 GB practical with OpenDML extensions for AVI 1.0 indexes |
| Bit depth | 1–32 bits per channel, up to 16-bit grayscale or 48-bit color | 8-bit 4:2:0 YUV (MPEG-4 ASP) |
| Compression | Lossless (LZW, Deflate, ZSTD, PackBits) or lossy (JPEG, WebP) | Lossy inter-frame (I/P/B frames, quarter-pel motion compensation) |
| Frame count | Multi-page possible but no playback timing | Native video timeline with frame rate metadata |
| Playback support | Image viewers (Preview, Photos, IrfanView) — no native browser TIFF | VLC built-in; Windows Media Player needs the Xvid codec installed; most hardware DivX/XviD players |
| Typical use | Print, archival, medical imaging, GIS rasters | Legacy DVD rips, P2P video circa 2003-2012, hardware-player archives |
Xvid (MPEG-4 ASP) uses a quantizer-based quality scale internally; on this page that's surfaced as named presets. Pick by what the file is for:
| Preset | Best for | Tradeoff |
|---|---|---|
| Lowest / Low | Quick proof clips, email attachments | Visible blocking on detailed TIFFs, motion mush |
| Medium | Casual playback on legacy DVD players | Good size/quality balance for 480p–720p output |
| High | Most archive use cases | Crisp text and edges on scanned pages |
| Very High (default) | Scientific imaging, timelapses you'll re-grade | File ~2-3x larger than Medium, near-transparent quality |
| Highest | Archival masters | Approaches I-frame-only sizes; minimal Xvid advantage over MJPEG |
If you need a hard file-size cap rather than a quality target, switch the mode to Constraint Quality and the converter will solve for a bitrate that fits.
Use Xvid when the playback device requires it — vintage standalone DVD players with DivX/Xvid certification, older Windows XP/7 machines without a modern codec pack, in-car head units from 2005-2012, and some industrial display panels. For any new project meant for web, phones, or modern TVs, H.264 in MP4 is more efficient and more compatible; convert your TIFFs to MP4 via TIFF to MP4 instead.
No. Chrome, Firefox, Safari, and Edge do not ship with Xvid or AVI container support. AVI files have to download and play in a desktop player such as VLC (which has Xvid built in) or Windows Media Player with the Xvid codec installed. If you need browser playback, choose WebM or MP4 as your output.
Both are MPEG-4 Part 2 Advanced Simple Profile codecs and produce broadly interoperable streams. Xvid is open-source under GPL and gives more low-level encoder controls; DivX was historically commercial with closed-source binaries and tighter hardware certification. A hardware player labeled "DivX Certified" will almost always play Xvid files too, but the reverse isn't guaranteed for the oldest devices.
Three common reasons: (1) Very High is the default Quality Preset — drop to Medium for a 2-3x smaller file. (2) The merge default holds each TIFF on screen for several seconds; shortening Image Duration to 1/24 second packs the same content into far less runtime. (3) If your TIFFs are 16-bit grayscale or 48-bit color, Xvid still has to downsample to 8-bit 4:2:0 YUV — high source contrast can defeat the quantizer until you raise the preset back up.
The pipeline assembles separate TIFF files into one video. If you have a single multi-page TIFF (common with fax archives and document scanners), split it into individual pages first — most desktop image tools (GIMP, IrfanView, ImageMagick convert in.tif out-%03d.tif) do this in one command — then upload the page files together.
Frame rate is derived from Image Duration: 1/24 second per frame produces a 24 fps video, 1/30 second yields 30 fps, 1 second per frame produces a 1 fps slideshow. For scientific time-lapses where each TIFF was captured at a real interval, pick the duration that matches your acquisition cadence; for cinematic playback of a DSLR timelapse, use 1/24 second.
The image-to-video pipeline produces video-only AVIs. If you need a soundtrack, convert the TIFF sequence to AVI first, then mux audio in a desktop editor (VLC's convert/save, FFmpeg, Shotcut, or DaVinci Resolve) — or use TIFF to MP4 and add audio in any modern editor that accepts MP4.
No. Xvid 1.3.7 shipped in December 2019 and the project has been dormant since. The encoder is mature and stable — there's no quality benefit to a newer version — but choose Xvid only when you specifically need MPEG-4 Part 2 AVI for legacy compatibility. For new archives, use a more modern codec.
Yes — if you want a flippable document rather than a playable video, Merge TIFF to PDF combines a folder of .tif/.tiff files into one multi-page PDF that opens in any reader. If the AVI you produce here is too big, run it through Compress XviD to shrink it without re-running the assembly.
