AVI to TIFF Converter

How to Convert AVI to TIFF Online

1. Upload Your AVI File: Drag and drop or click "Add Files" to select an .avi video. DV-AVI camera captures, OBS / VirtualDub recordings, surveillance exports, and AVI screen captures all work. Batch upload is supported.
2. Pick the Frame Selection Mode: Choose Specific Frame (default) and enter a timestamp in seconds to grab a single still — useful for cover frames or evidence stills. Choose Multiple Screenshots to extract a sequence at a chosen rate, from every 0.1 s (10 fps) up to every 10 s. A 60-second clip at 1 frame per second yields 60 TIFFs.
3. Set Quality Preset and Compression Type (Optional): Quality Preset defaults to Very High; drop to High / Medium / Low only if you need smaller files. Compression Type controls the TIFF encoding: LZW (lossless, widest support), DEFLATE (lossless, smaller than LZW), PackBits (lossless RLE, simple decoders), CCITT Fax 4 (bilevel only), NONE (uncompressed, maximum compatibility), JPEG / JP2K / WebP (lossy, much smaller), or ZSTD (modern lossless, fastest).
4. Resize, Pick Extension, and Convert: Optionally pick a resolution preset (144p–4320p), enter custom width × height, or scale by percentage. Choose .tiff or .tif as the file extension. Click Convert and download. Files process in your browser session — no sign-up, no watermark.

Why Convert AVI to TIFF?

AVI is Microsoft's RIFF-based container, introduced with Video for Windows on November 10, 1992. It's still the lingua franca for older camcorders, scientific capture cards, surveillance DVRs, and legacy Windows software — but you can't open an AVI in Photoshop, send a frame to a print shop, or hand a still to a forensic analyst. TIFF, designed by Aldus in the late 1980s and now maintained by Adobe (TIFF 6.0 spec, June 1992), is the lossless image format those workflows expect. Common reasons to convert AVI → TIFF:

• Forensic and evidence stills — Pulling a frame for chain-of-custody work needs a format that records exactly what came off the source. TIFF with NONE or LZW compression preserves every pixel; JPEG would re-encode and add quantization artifacts that defense experts can challenge.
• Print-ready stills from video — Magazines, books, and large-format prints want 300 DPI uncompressed images. A frame from an AVI saved as a print-bureau TIFF skips the JPEG generation loss entirely.
• VFX and compositing image sequences — After Effects, Nuke, DaVinci Resolve, and Blender all consume TIFF / DPX / EXR sequences as native input. Multiple Screenshots mode at the source frame rate produces a frame-accurate sequence ready for the timeline.
• Scientific and medical imaging — Microscopy, ultrasound, and high-speed camera capture rigs often export AVI but demand TIFF for analysis in ImageJ / Fiji / MATLAB. MATLAB's imread and ImageJ's TIFF importer both round-trip pixel data without modification.
• Archival of CCTV and surveillance frames — In 2010 the U.S. National Archives designated AVI as an acceptable preservation wrapper, but stills extracted for case files are usually stored as TIFF for cross-software compatibility decades from now.
• Reverse pipeline for TIFF to JPG or TIFF to PNG — Once you have the lossless master, you can encode smaller deliverables without ever touching the AVI again.

AVI vs TIFF — What You Are Trading

A 1080p uncompressed TIFF is roughly 1920 × 1080 × 3 bytes ≈ 5.9 MB per frame. Extract every frame of a 30-second 30 fps clip uncompressed and you'll generate ~5.3 GB across 900 files — pick LZW or DEFLATE if disk space matters.

Frequently Asked Questions

Will the extracted TIFF be truly lossless?

If you pick NONE, LZW, DEFLATE, PackBits, or ZSTD for compression, the saved TIFF is a bit-exact copy of the decoded video frame — no quantization, no chroma subsampling beyond what the source codec already applied. The catch: most AVI files use a lossy video codec (Xvid, DivX, Cinepak, MJPEG), so the TIFF can only be as faithful as the codec's decoded output. To get a fully lossless chain, the AVI itself must use an uncompressed or lossless codec like Lagarith, HuffYUV, or FFV1. JPEG / JP2K / WebP TIFF compression is additionally lossy and should be avoided for forensic or archival work.

Why is my TIFF so much larger than the original AVI?

Because video codecs use temporal compression — a 30-second 1080p AVI at 5 MB stores frames as small differences from neighbors. TIFF stores every pixel of every frame independently. Uncompressed 1080p RGB is ~5.9 MB per frame, so 30 seconds at 30 fps becomes ~5.3 GB. Use LZW or DEFLATE to shave 40-65% off that, drop resolution to 720p, or extract fewer frames (every 5 seconds instead of every frame).

Should I pick .tif or .tiff for the extension?

Functionally identical. Both contain the same TIFF byte stream — .tif is the original 8.3 DOS extension; .tiff is the four-letter modern variant. Some legacy Windows tools and old print workflows expect .tif; macOS, Linux, Photoshop, and every modern application accept both. If you're feeding a specific pipeline, match what it expects; otherwise either is fine.

How do I extract one frame at an exact timestamp?

Use Specific Frame mode and enter the timestamp in seconds (the timestamp box accepts decimals, so 12.5 picks the frame at 12.5 seconds). The extracted frame is the closest source frame to that timecode — for a 30 fps source, that's accurate to ±33 ms. For sub-frame accuracy (e.g., motion-interpolated mid-frame stills), no online tool can do it from a compressed AVI; you'd need optical-flow software like Twixtor or RIFE.

What's the difference between TIFF and PNG for video frames?

Both are lossless raster formats. PNG is locked to RGB or RGBA at 8 or 16-bit, uses DEFLATE, and is universal on the web. TIFF is more flexible — it carries arbitrary bit depths up to 32-bit float, supports CMYK / L*a*b* / multispectral color spaces, holds multiple images per file, and embeds richer metadata for print and scientific workflows. Pick PNG for web-bound stills; pick TIFF when the destination is print, forensics, scientific analysis, or a VFX pipeline. See AVI to PNG for the PNG path.

Can I extract every frame as a numbered TIFF sequence?

Yes — use Multiple Screenshots at a rate matching your source frame rate (24 / 25 / 30 / 50 / 60 fps presets are available, or set a custom interval). The output is a set of TIFFs you can download as a ZIP. Compositing apps will read the sequence by selecting the first frame and enabling "TIFF sequence" in the import dialog.

Does TIFF support transparency from the source?

TIFF supports an alpha channel (RGBA). However, AVI frames are almost always opaque — RGB or YUV without an alpha channel, since video codecs don't carry transparency outside niche formats like WebM with VP9-alpha or specialized ProRes 4444. So in practice your AVI-sourced TIFFs will be flat RGB. If you need alpha, the source needs to be a format that carries it.

Is there a hard file-size limit on a single TIFF?

Classic TIFF uses 32-bit offsets and tops out at 4 GB per file. For larger images — gigapixel scans, hyperspectral cubes, microscopy mosaics — the BigTIFF extension (LibTIFF 4.x, stable since 2011) replaces those offsets with 64-bit values and effectively removes the cap. Single video-frame TIFFs from a 4K or below source will never come close to 4 GB, so the limit only matters if you're embedding many pages into one multi-page TIFF.

Can I batch convert several AVI files at once?

Yes. Drop in multiple AVIs and each converts in parallel within your browser session. Settings can apply to all files or be set per file. Download individually or as a single ZIP. For a single multi-clip job — for example, pulling cover stills from 50 surveillance AVIs — Multiple Screenshots at every 30 seconds with LZW compression typically finishes in a few minutes.
