Need help?JPEG to AV1 Converter
This tool takes a JPEG still image and encodes it as an AV1 video — a single frame held on screen for a duration you choose, with no motion and no audio. AV1 (AOMedia Video 1) is a modern, royalty-free video codec, so the result is a short clip, not a photo. If you actually want a smaller still image, you almost certainly want AVIF instead — see the format comparison below before you convert.
AV1 vs AVIF — Don't Confuse Them
AV1 and AVIF are easy to mix up because AVIF is built from AV1, but they are not interchangeable. AVIF is "one frame of AV1 compression stored as an image" inside the HEIF container, per the AV1 Image File Format specification. AV1 on its own is a video stream.
| AV1 (this tool's output) | AVIF | |
|---|---|---|
| Type | Video codec / clip | Still-image format |
| Based on | AV1 bitstream | AV1 intra-frame coding in HEIF |
| Plays / opens as | A video (single still, fixed duration) | A photo |
| Has a duration | Yes — you set it | No |
| Use when | You need a video container target | You need a smaller photo |

.av1 output here |
AV1 video in a Matroska wrapper with a non-standard .av1 extension; VLC and mpv open it, extension-keyed players need it renamed to .mkv |
| Audio in this tool | None — a still image carries no audio track |
How to Convert JPEG to AV1
- Upload Your JPEG File: Drag and drop or click "+ Add Files". JPG, JPEG, and JFIF inputs are accepted; you can add several images at once.
- Set the Duration: Open Advanced Options and use Duration to choose how long the still is held — the default is 5 seconds per frame.
- Pick Merge or Per-image and a Background Color: Choose Merge images to combine multiple stills into one clip or Video per image for separate files; set the Background Color used to pad to the video frame (default White). The codec is fixed to AV1, and Quality Preset defaults to Very High.
- Convert and Download: Click "Convert" to get your AV1 clip. No sign-up, no watermark.
Frequently Asked Questions
Is the output a real video file or a still image?
A video. The tool encodes your JPEG as an AV1 clip that displays the single frame for the duration you set. There is no motion and no audio — it is a static image rendered as a video stream. If you wanted a compressed photo, use JPG to AVIF instead.
Why would I turn a JPEG into an AV1 video at all?
It is a niche need. The usual reasons are creating a fixed-length title or filler card for a video timeline that already uses AV1, producing a still "slide" to concatenate with other AV1 clips, or testing an AV1 decode pipeline with a known single frame. For everyday photo compression, AVIF is the right target.
Will the .av1 file play in my media player?
Not always. The output is AV1 video in a Matroska wrapper, but the .av1 extension is non-standard: FFmpeg-based players like VLC and mpv open it directly, while consumer players that judge files by extension refuse the unfamiliar name (renaming it to .mkv — same bytes — usually fixes that). If you need broad playback, convert to a container target such as JPEG to MP4 or JPEG to WebM — WebM and MP4 both carry AV1.
Does AV1 keep the full color and detail of my JPEG?
AV1 supports 8 and 10-bit color (up to 12-bit in its Professional profile), so it has more than enough range to hold an 8-bit JPEG. With Quality Preset at the default Very High, the visible difference from the source frame is minimal; lower presets trade fidelity for a smaller file.
Does the AV1 clip include sound?
No. A JPEG has no audio, so the resulting video has no audio track. If you need a soundtrack over a still, create the clip here and add audio in a separate video-editing step.
Is AV1 actually free of licensing fees?
Yes. AV1 was created by the Alliance for Open Media specifically as a royalty-free codec, which is the main reason it was developed as an alternative to patent-licensed codecs like HEVC. Anyone can encode, decode, and distribute AV1 without per-use royalties.
Which players and browsers can decode an AV1 file?
Software support is broad; hardware support is where it varies. On desktop and Android, Chrome 70+, Firefox 67+, Opera, and Chromium-based Edge all decode AV1, and VLC and mpv open it locally. Apple is the gap: Safari plays AV1 only on devices with a hardware AV1 decoder — recent iPhones (A17 Pro onward) and Apple-silicon Macs from the M3 generation — with no software fallback, so older Macs and iPhones can't. That patchiness is another reason AV1 video is a niche target for a single still; JPG to AVIF uses the same compression as a photo and opens far more widely.
How long do you keep my uploaded file?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, and your files are never shared or made public.
