TS to AVIF Converter

How to Convert TS to AVIF Online

1. Upload Your TS File: Drag and drop or click "+ Add Files" to select the MPEG transport stream. Batch upload is supported, and conversion settings apply to every file in the queue.
2. Pick Quality Preset and Frame Selection: Defaults to Very High quality. Drop to High, Medium, Low, or Lowest to shrink output, or switch to Specific file size for a hard byte/kilobyte/megabyte target. Under Frame Selection, set Specific Frame and enter the timestamp in seconds (for example 12.5) to grab the still you want; otherwise the first frame is captured.
3. Resize the Output (Optional): Use Resolution Percentage to scale (10-100%), pick a Preset Resolution (144p through 4320p), or enter custom Width x Height in pixels. Aspect ratio locks by default when only one dimension is set.
4. Convert and Download: Click "Convert". Frames are decoded from the TS container and re-encoded with AV1, then packaged as AVIF. No watermark, no sign-up, files auto-delete from our servers.

Why Convert TS to AVIF?

TS (MPEG Transport Stream, ISO/IEC 13818-1) is the broadcast and IPTV container — it's what HLS uses for streaming, what DVB/ATSC tuners record, and what most IP camera DVRs spit out. The footage inside is video, but the moment you want to share a single still, a thumbnail, or a poster image, you need an image format. AVIF (AV1 Image File Format, released February 2019 by the Alliance for Open Media) gives you that still at roughly half the file size of JPEG at matched perceptual quality, with HDR and 10/12-bit color support built in.

• HLS / IPTV thumbnails — pull a representative frame from a .ts segment and ship it as a 5-15 KB AVIF preview. Cuts your CDN bandwidth for poster art versus a 30-50 KB JPEG.
• Security camera evidence snapshots — DVR/NVR exports often land as TS. Extract the exact second of an incident and store it as a tiny lossless or near-lossless AVIF for archival.
• Broadcast & news desk stills — capture a key frame from a DVB recording for a story graphic; 10-bit AVIF preserves the gradient skies and skin tones that 8-bit JPEG posterizes.
• Web hero images from video — designers grabbing a cinematic frame from a captured TS feed get a sub-50 KB hero image that Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+ render natively (caniuse.com/avif, ~94% global support).
• AI training datasets — extract specific frames at known timestamps to build a labelled image corpus; AVIF saves 40-50% of disk vs JPEG with no perceptual loss.
• Photographer contact sheets from video — pick the sharpest moment from a clip without dragging a 4 GB master video into Lightroom.

TS vs AVIF — Format Comparison

AVIF Quality Preset Guide

Per Netflix's published benchmarks against representative JPEG and WebP test sets, AVIF averaged roughly 50% file-size reduction over JPEG at matched perceptual quality, with the largest gains on skin tones, skies, and smooth gradients.

Frequently Asked Questions

How do I extract a frame at a specific timestamp from my TS file?

Expand Advanced Options, scroll to Frame Selection, choose Specific Frame, and enter the Time in seconds (decimals allowed, for example 47.25 for 47 and a quarter seconds). The decoder seeks to the nearest I-frame and then steps forward to your exact timestamp. If you leave this blank, the first decodable frame is exported.

Why does my AVIF look slightly different from VLC's snapshot of the same TS frame?

Two reasons. First, MPEG-TS often uses B and P frames that reference adjacent frames — seek-to-second decoders can land on a neighbouring frame depending on GOP structure. Second, AVIF's AV1 encoder applies its own filtering and quantization, so a Quality preset below Very High will show subtle differences in gradient-heavy regions. Pick Very High or enable Lossless for a pixel-faithful match.

Can I extract multiple frames from one TS file?

Not in a single click on this page — the still-image converter outputs one AVIF per upload. If you need a sequence (every Nth frame, an animation), use our TS to GIF page for an animated output, or upload the same TS multiple times with different Specific Frame timestamps.

Will all browsers display my AVIF?

Chrome 85+ (Aug 2020), Firefox 93+ (Oct 2021), Safari 16.4+ (March 2023), and Edge 121+ (Jan 2024) decode AVIF natively. Per caniuse.com that's roughly 94% of global browser traffic as of 2026. For the remaining ~6% (mostly older Safari and corporate-locked browsers), use a <picture> element with a JPEG or WebP fallback.

Why is my TS file so much larger than the resulting AVIF?

A .ts stream is a full video — 30 or 60 frames per second of motion data, plus audio, plus PSIP metadata, often 1-10 Mbps. The AVIF is one still frame stripped from that stream. A 500 MB hour-long TS recording becomes a single 20 KB AVIF when you extract one moment.

Should I pick AVIF or stick with JPEG for archival stills from a TS recording?

If your archive will be read in 2026+ by software you control (Lightroom, ImageMagick, modern browsers), AVIF saves ~50% storage and preserves more dynamic range with 10/12-bit color. If the archive must open in legacy tools or be emailed to recipients on Windows 10 without modern image viewers, JPG is still the safer interchange format. Many teams store the AVIF master and generate JPEG on demand.

Does this support HDR TS recordings (HLG, PQ)?

The converter extracts the frame's pixel data; if the source TS carries HDR metadata (HLG from a broadcast feed or PQ from a UHD Blu-ray rip), 10-bit AVIF can preserve the wider color volume. Choose a higher Quality Preset to avoid banding in the brightest highlights and deepest shadows. SDR sources are tone-mapped normally to 8-bit.

What if I just want the whole TS as a playable video, not a still?

Use TS to MP4 to repackage the transport stream into the more universally playable MP4 container, or TS to WebM for an AV1/VP9 video output that pairs naturally with AVIF stills on a modern site.
