WebM to TIFF Conversion FAQ
How do I extract frames from a WebM video as TIFF images?
+
Upload the WebM and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as an individual TIFF file and the full set is bundled into a ZIP archive for download. WebM is a strict subset of Matroska that Google published in 2010 specifically to give HTML5 video a royalty-free container. TIFF is the Tagged Image File Format from 1986, and it is the format scanning, publishing and archiving industries standardised on.
Will subtitles show up in the TIFF frames I extract?
+
Not if they are a real subtitle track. A WebM keeps subtitles as their own stream and the player draws them over the picture at playback time, so the decoded frame the converter writes out as a TIFF has clean pixels underneath. Subtitles that were burned into the video before it ever became a WebM are a different matter — by then they are part of the image and every extracted frame keeps them.
Does the TIFF output support transparency?
+
The format does, but the source has no alpha to give it — video frames and rendered pages are fully opaque by nature, so every pixel arrives solid. The alpha channel is still useful afterwards: it means you can cut a subject out of the TIFF later without changing format again. TIFF handles CMYK, 16-bit depth, embedded ICC profiles and multi-page documents, which is exactly what print and archival workflows require.
How big will the TIFF files be?
+
Larger than you might expect, because TIFF keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page. TIFF is a container more than a codec: it can hold uncompressed, LZW, ZIP or even JPEG data, at up to 32 bits per channel, with multiple pages in one file.
At what resolution does each extracted TIFF frame come out?
+
The same resolution as the WebM video — a 1080p WebM produces 1920×1080 TIFF frames; a 4K WebM produces 3840×2160 TIFF frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Can I extract every single frame from WebM as TIFF?
+
Yes, but be careful with file count — a 30fps 1-minute WebM produces 1,800 TIFF frames. We pack them into a ZIP automatically. For longer clips, the "1 per second" option (60 frames) or specific timestamps gives a manageable result.
Will the extracted TIFF images preserve the WebM color grading?
+
Yes — colour is decoded with the matrix the source WebM uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR on extraction to TIFF because most TIFF formats (PNG, JPG) cannot store HDR pixel ranges natively.
What is the file size of one extracted TIFF frame?
+
Depends on resolution and TIFF codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p WebM produces ~50 GB total.
Does the extracted TIFF retain EXIF camera metadata?
+
The WebM container does not store per-frame EXIF the way a still camera does, so the TIFF files come out with empty EXIF. We embed a `creation_time` field pointing at the source frame timestamp so you can re-sort the bundle by capture order.
How long does frame extraction from WebM to TIFF take?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute WebM → TIFF bundle finishes in about a minute regardless of frame count, because the bottleneck is the TIFF encoder, not the WebM demuxer.
Can I extract frames at specific timestamps in the WebM?
+
Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one TIFF file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
Is my WebM video private during frame extraction?
+
Yes — same privacy model as every conversion. Source video and extracted TIFF frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
