How to Extract PNG and JPG Frames from AV1 Video

Practical guide to extracting still PNG and JPG images from AV1 video files, including output settings, quality limits, and common conversion problems.

Before you start

This workflow turns a selected frame from an AV1 video into a PNG or JPG image. AV1 is a compressed video format, so the result will always be based on decoded video frames rather than original camera stills. You need the video file available locally and a media tool that can decode AV1 and export still images. Some desktop video editors and command-line utilities can do this directly; browser-based converters may require uploading the file to a service, which affects privacy and file handling.

Before converting, confirm the source file actually contains AV1 video. Check the file properties or media information panel for the codec name. Also note the recording format and pixel dimensions, because these determine the maximum resolution of the extracted image. A still frame cannot gain detail that was not present in the compressed video.

Step-by-step instructions

Open the AV1 file in your media tool. Move through the timeline one frame at a time until you reach the frame you want. Avoid choosing a frame that is fast-moving or heavily compressed, because AV1 encoding can soften fine detail and create blocking artifacts that become more visible in a still image.

Find the still-image export or snapshot function. Most video tools call this something like snapshot, export frame, save frame, or capture still. If the tool offers a choice, select PNG when you need lossless output or plan to edit and save the image again. PNG preserves the decoded frame without adding JPG compression artifacts, but the file can be noticeably larger.

Choose JPG when you need a smaller file for sharing, web upload, or email. For JPG, set the quality or compression level if the tool exposes it. A quality of around 90 or a high-quality preset usually keeps the image acceptable while reducing file size. Lower quality settings can introduce additional artifacts beyond those already present in the AV1 source.

If the tool shows resolution options, keep the native pixel dimensions of the video frame unless you have a specific reason to resize. Changing the aspect ratio by scaling width and height separately will distort the image. For ordinary exports, use the source frame size or scale both dimensions proportionally.

Save the image to a known folder. Do not overwrite the original video file. Use a descriptive file name that includes the source clip or time position so that you can find the same frame again if needed.

Check the output

Open the exported image in an image viewer and compare it side by side with the paused video frame. Check the pixel dimensions to confirm that the image has the expected resolution and aspect ratio. Look for visible blocking, banding, blur, or color shifts, especially in dark areas or around moving objects. These may come from AV1 compression and cannot be fixed by converting to another image file format.

PNG exports do not introduce JPG artifacts, but they also do not remove artifacts that were already encoded into the video. If the image contains a logo or overlay, verify that it is complete and positioned correctly. For JPG output, view the file at full size to make sure compression has not blurred small text or edges too much.

Common problems and next steps

If the media tool cannot open the AV1 file, the local AV1 decoder may be missing. On many systems, the same application can play the video only when a suitable decoder is installed or when the file is in a compatible container. Try a current version of the tool or a different local application that lists AV1 support.

When an AV1 to JPG conversion service is used instead of a local export, the output depends on the service settings and its decoder. Keep in mind that JPG is an image format, not a video format, so converting at a specific AV1 bitrate or frame rate is not meaningful for a still image. A service that claims to convert the whole video to JPG is usually extracting frames rather than creating one JPG per video frame by default.

If the exported image appears darker or flatter than the video on screen, check whether the player applies color adjustments that the still export does not include. High dynamic range or wide-gamut sources may look different after export because the image path changes how tone and color are mapped. In that case, export from a tool that preserves the same color handling as the preview.

For a subtle frame, repeat the export from the same timeline position. If you need several frames, export them individually and keep the original video unchanged. Avoid repeatedly saving a JPG as JPG, because each generation can add compression noise. Use PNG for intermediate editing work and create the final JPG from that lossless copy.
