Supports: PSD
A .psd is a layered Photoshop document — a still image with editing state attached. AV1 is a video codec published by the Alliance for Open Media. Converting between them therefore does something specific and slightly unusual: the document is flattened to one rendered frame, that frame is held on screen for a fixed duration, and the result is encoded as a short, silent video clip. This page exists mainly for people feeding stills into a video pipeline, and for anyone who was handed an .av1 file and needs to understand what it actually is.

Three details explain most of what people find surprising about the result.
The clip runs at 1 frame per second. A still has nothing to animate, so the encode holds one picture for the duration you chose at a 1 fps rate — a 5-second clip is five identical frames — and B-frames are switched off, because predicting between identical pictures buys nothing and adds a start-time offset. That is why the files are so small: after the first frame, there is almost nothing left to code.
Transparency is flattened, not preserved. Video frames are stored as YUV and cannot carry an alpha channel. Anything transparent in the PSD is composited onto the "Background Color" before encoding, and the same colour fills any letterbox bars introduced by a fixed resolution. White is the preselected fill.
Colour is subsampled. The output is 8-bit 4:2:0, which halves the chroma resolution horizontally and vertically for player compatibility. On photographic artwork this is invisible; on saturated flat colour and thin coloured type — exactly what a lot of Photoshop work is — edges soften slightly compared with the source. If a design needs pixel-exact colour, it belongs in an image format, not a video one.
Large documents are also brought down: images wider or taller than 4096 pixels are scaled to fit before the encode, because that is the limit the frame-input stage handles reliably.
Because AV1 is a video codec, not an image format. There is no way to write "an AV1 picture" here: the pipeline flattens the PSD to one frame, loops that frame for the chosen duration, and encodes it as a clip. If you wanted a still, use PSD to PNG for lossless artwork, PSD to JPG for photographs, or PSD to WebP for the web.
The bytes are fine; the name is the problem. The output is AV1 video inside a Matroska container, and most players decide what a file is from its extension — .av1 is not a container extension anyone registers. Rename it to .mkv and it opens normally. VLC and mpv sniff the contents and will play it either way. For something that plays everywhere without renaming, run it through AV1 to MP4 or AV1 to WebM.
No, and there is no audio control on this page — the audio codec group is hidden for image sources because there is no audio track to convert. Add music or narration afterwards in a video editor.
No. Everything is read from the document's flattened composite — the single merged picture Photoshop stores alongside the layer data. Layers, masks, adjustment layers, smart objects and live text are baked in and cannot be recovered from the video. Keep the original .psd. If the composite looks wrong or empty, re-save from Photoshop with the "Maximize compatibility" preference enabled so a correct composite is embedded.
Three modes render here: "Quality Preset" (preselected, and the right choice for almost everyone), "Constant Quality" with a CRF slider on AV1's 16-63 scale where lower is better, and "Constraint Quality", which pairs a CRF with a maximum bitrate. Bitrate and target-file-size modes are deliberately hidden for image sources, because a still has no source bitrate to scale from. For a single frame, leave the preset alone — the file will be small regardless.
It is exactly the "Image Duration" you pick, preselected at 5 seconds. The dropdown spans single-frame durations such as 1/30 s and 1/24 s all the way up to 10 seconds per frame. Upload several PSDs with the "Merge images" strategy and each contributes its own duration to one continuous clip; choose "Video per image" to get a separate clip per document instead.
AV1 is an open codec published by AOMedia and is the modern efficiency leader, which matters when the clip is going onto a platform that re-encodes or streams it. For a single held frame the practical difference is small — the file is dominated by one keyframe either way — and H.264 plays on far more devices. Pick AV1 when the destination is a modern browser or a pipeline that already expects it, and H.264 when it just needs to play.
Partly. Safari has only partial AV1 support from version 17, and on Apple devices decoding generally depends on hardware AV1 support rather than software. Chrome from 70, Firefox from 67, Edge from 121 and Opera from 57 decode it, which caniuse puts at roughly 94% of tracked traffic once partial support is counted. If the audience is broad, convert to MP4 with H.264 instead.
