How to use the batch video converter
Add videos
Select multiple files from your device or drag them into the drop area. You can add more files in a second selection. Click a filename to preview that source, or use the remove button beside it to take it out of the queue before conversion.
Set the output for the batch
Choose one output format for all files. By default, the batch video converter exports MP4 at the original resolution with quality set to 65. To produce audio files, choose an audio format in the same menu. The video resolution and quality controls then disappear.
Convert and download
Start the batch. Files are processed in list order on your device. Each successful conversion adds a download link showing the output name and file size. You can save that file while the remaining items are still running.
Which output format will every file in the batch use?
| Output | Encoding | When to choose it |
|---|---|---|
| MP4 · M4V | H.264 + AAC | MP4 is the default. Choose M4V if the receiving app asks for a .m4v file. Both presets write the same kinds of video and audio streams in an MPEG-4 container. |
| MOV | H.264 + AAC | For a QuickTime viewing copy. Check the requested video codec before using this for an editing handoff. A ProRes master needs a ProRes encoder. |
| MKV | H.264 + AAC | Choose MKV for a player or library that accepts Matroska. The batch controls do not include a track selector. If a particular language, commentary track or subtitle is essential, check the streams in the downloaded copy before replacing anything in your library. |
| WebM | VP8 + Opus | For web playback, this batch video converter writes VP8 video with Opus sound. Check the codec if your publishing platform specifically requests VP9 or AV1. |
| MPG | MPEG-2 + MP2 | Choose MPG when the destination requests MPEG-2 video with MP2 sound. The encoder sets the video frame rate to 25 frames per second. Check that rate against your delivery requirements if the original was recorded at a different frame rate. |
| OGV | Theora + Vorbis | For a Theora video delivery. Select this extension to keep the picture when the receiving player also expects Vorbis sound. |
| MP3 | MP3 | For MP3 output, the batch video converter encodes each soundtrack in variable-quality mode. For a specific choice of 128, 192, 256 or 320 kbps on a single file, use the video-to-MP3 tool. |
| AAC · M4A | AAC · 160 kbps | Both choices encode AAC audio at 160 kbps. M4A packages the audio in an MPEG-4 container. Use the extension requested by the receiving player or editor, especially when its import dialog filters files by extension. |
| WAV · FLAC | PCM 16-bit / FLAC | WAV writes 16-bit PCM audio. FLAC uses lossless compression. Both are useful when you need decoded audio for further work. Converting an already compressed soundtrack to either format cannot recover details lost in its earlier encoding. |
| OGG | Vorbis | For an audio player that accepts Vorbis. Unlike the AAC and M4A presets, this output does not use AAC encoding. |
Batch video converter settings for resolution and quality
How the height limit works
Original keeps the source dimensions, with odd dimensions rounded up to even values for encoding. The other choices are maximum heights of 360, 480, 720, 1080 and 2160 pixels. At 720p, a square-pixel 1920 × 1080 source becomes 1280 × 720. A 640 × 360 source stays at 640 × 360 in the same batch.
What 35, 65 and 85 change
These quality presets affect video encoding for MP4, M4V, MOV, MKV and WebM. A higher value gives the encoder more room to retain picture detail. The numbers are not percentages of the original size. MPG and OGV use their own encoding settings, so the quality menu is hidden for those formats.
What happens to source quality?
Even with Original selected, the batch video converter re-encodes each file. Keeping the same extension still produces a new copy. If you need to keep an untouched master, retain the input file. For a size limit expressed in megabytes, check the size next to the completed download. The batch form has no target-size field.
How can I tell downloads with the same filename apart?
The batch video converter prefixes each download with its queue number. It keeps the source name up to the last extension, then adds the output extension. With MP4 selected, clip.mov and clip.webm therefore produce the two distinct names below.
| Source | Result · MP4 |
|---|---|
| clip.mov | 1-clip.mp4 |
| clip.webm | 2-clip.mp4 |
How to save finished files and retry unfinished ones
Match a failed row to its source file
The processing indicator identifies the active row. The ready count records successful outputs. A failed row can be followed by a successful one, so reaching the last position does not necessarily mean every file has a download. Match a reported failure number to the same number in the input list.
Resume with the same settings
Cancel stops the current conversion. Results that already have download links stay available in the open tab. When you select Retry unfinished files, the batch video converter skips completed rows and uses the original settings for the rest. A partially encoded file is started again from its beginning.
Start over with different settings
Once conversion begins, the file list and settings are locked, including after cancellation. To change a setting or remove a problematic source, download the results you want and select Start a new batch. This clears the list and its download links. Files you already saved remain on your device.
Batch video converter questions about files and downloads
Can I add a shared link to the batch video converter?
This queue accepts local files through the file picker or by drag and drop. Download the media files to your device first. A link to a watch page or shared folder does not add its contents to the batch.
The preview is blank. Did conversion fail?
Look for the file in the results list. A download link means the encoder produced a file. The browser has its own playback support, so an MKV or MPG may need to be opened in a desktop player. A number in the failure message identifies a row that did not produce a download.
Can I save the whole queue as a ZIP or one movie?
The batch video converter offers individual downloads only. To create a ZIP, save the files first and compress them on your device. If you need one continuous video, open Merge video clips and arrange the sources in playback order there.
Can I close the tab and resume later?
The browser holds the current queue and its generated files in memory. Reloading or leaving the page releases those results. Download the completed files you need before closing the tab. On a new visit, select any outstanding sources again.
