Lower is better quality and a bigger file. 18 looks identical to the source, 23 is the default, 28 and above shows visible softening.
Frames per second. Keep the source rate unless a platform asks for a specific one; 15–20 fps is plenty for GIFs.
Only used for PowerPoint files and single still images: how long each slide or picture stays on screen.
Auto uses AAC for MP4/MOV and Opus for WebM. Copy keeps the original sound untouched when the new format supports it.
192 kbps is transparent for music; 128 kbps is enough for speech.
Width of the animation in pixels; height follows the aspect ratio. 480 px suits chats, 720 px or more gives a high-quality GIF but a much larger file.
GIF holds at most 256 colors. Fewer colors make a smaller file but cause banding on gradients and skin tones.
Mixes palette colors in a fine pattern to hide banding. Sierra gives the smoothest result; none gives the smallest file.
Whether the animation repeats endlessly or plays one time and stops.
Optional. Seconds (e.g. 75) or minutes:seconds (1:15). Leave empty to start at the beginning.
Optional. Same format as the start time. Leave empty to keep everything up to the end.
The converted file will be at or just under this size.

What does an online video converter actually change?
It decodes the clip and writes it again in the container and codec you pick, optionally at a new resolution, frame rate or size. MP4 with H.264 is the default because it plays on practically every device made since 2010.
Video formats and codecs, side by side
| Codec | Released by | Fits in | Plays on |
|---|---|---|---|
| H.264 / AVC | ITU-T and ISO/IEC MPEG, 2003 | MP4, MOV, MKV, M4V | Practically everything, including old phones and TVs |
| H.265 / HEVC | ITU-T and ISO/IEC MPEG, 2013 | MP4, MOV, MKV, M4V | iPhones since iOS 11, recent Android, Macs; Windows needs an extra decoder |
| VP9 | Google, 2013 | WebM, MKV, MP4 | Chrome, Firefox, Edge, Android; Safari on newer macOS |
| AV1 | Alliance for Open Media, 2018 | WebM, MKV, MP4 | Current browsers and recent phones; older hardware decodes it slowly |
A video file is two layers. The outer layer is the container, which decides the extension and how video, audio and metadata are packed: MP4 is MPEG-4 Part 14, MOV is Apple's QuickTime format from 1991, MKV is the open Matroska format, WebM is Google's web-focused cut of Matroska, and AVI dates back to Microsoft in 1992. The inner layer is the codec, the method that squeezes the frames.
Most playback problems come from the codec, not the extension. An iPhone films in HEVC by default, so its MOV files can fail on a Windows PC that lacks Microsoft's HEVC Video Extensions, even after the file is renamed. Converting to MOV to MP4 with H.264 fixes that. Matroska files from screen recorders and downloads go the same way through MKV to MP4, and web recordings through WebM to MP4.
Every setting in the video converter, in plain words
Convert to lists 13 video containers (MP4, MOV, MKV, WebM, AVI, WMV, FLV, M4V, MPEG, MPG, 3GP, TS, OGV), four animated image formats (GIF, WebP, APNG, AVIF) and PDF, which puts one frame on each page.
- Video codec: Auto, H.264, H.265, VP9 or AV1, shown for MP4, MOV, MKV and M4V
- Resolution: same as source, or a height from 2160p down to 240p; the width follows the aspect ratio and videos are never upscaled
These settings control how much detail survives and how smooth motion looks.
- Quality (CRF): 0 to 51, default 23; lower means more detail and a bigger file
- Frame rate: keep the source or force 60, 50, 30, 25, 24, 20, 15, 12 or 10 fps
- Seconds per slide: 1 to 60 seconds, used only for slides and still images
Sound is kept by default and re-encoded to suit the new container.
- Remove audio: drop the sound track entirely
- Audio codec: Auto (AAC for MP4 and MOV, Opus for WebM), Copy original, AAC, MP3 or Opus
- Audio bitrate: 96 to 320 kbps, default 192 kbps
Shown when the output is GIF, WebP, APNG or AVIF.
- Width in pixels, 480 px by default
- Colors (GIF only): 256, 128, 64 or 32
- Dithering (GIF only): None, Bayer, Floyd–Steinberg or Sierra
- Loop: forever or play once
Cut the clip and cap its size in the same conversion.
- Start at and End at: seconds (75) or minutes:seconds (1:15)
- Limit file size with a Maximum size in KB or MB, 25 MB by default
Which video conversion fits your file
iPhone or QuickTime clip
MOV in HEVC that will not open on Windows or in an upload form. Convert to MP4 with H.264.
iPhone or QuickTime clipScreen recording or download
MKV from OBS or a media server. MP4 opens in phones, PowerPoint and social apps.
Screen recording or downloadBrowser recording
WebM from Chrome, screen recorder extensions or Discord clips that iPhone editors reject.
Browser recordingReaction GIF into a video
Turn a heavy GIF into a far smaller MP4 that platforms accept as a video post.
Reaction GIF into a video4K that is too big to share
Scale 2160p footage down to 1080p and cut the file size several times over.
4K that is too big to shareSmaller files for new devices
Re-encode H.264 as H.265 to save space when every viewer has a recent device.
Smaller files for new devices
Converted video won't play? Common causes
Black screen with sound on a Windows PC
The file is still HEVC or AV1 and the PC has no decoder for it. Convert again with Video codec set to H.264.
MOV plays on a Mac but the editor or LMS rejects it
Some upload forms only accept MP4. Choose MP4 output; the picture stays the same, only the wrapper and codec change.
No sound after converting to WebM
WebM only carries Opus or Vorbis audio. Leave Audio codec on Auto instead of forcing AAC or Copy original.
The new file is larger than the original
A low CRF value or upscaled frame rate can inflate the size. Return Quality (CRF) to 23, keep the source frame rate, or set Limit file size.
The clip starts or ends at the wrong moment
Check the time format in Start at and End at: 1:15 means one minute fifteen seconds, while 115 means 115 seconds.

Video converter questions
What is the difference between a video format and a video codec?
The format, or container, is the file wrapper you see in the extension: MP4, MOV, MKV, WebM. The codec is the compression method used for the picture inside it, such as H.264 or AV1. A player needs to understand both, which is why an MP4 can still refuse to play when its codec is unsupported.
Which output should I choose if I just want the video to play everywhere?
MP4 with Video codec on Auto, which writes H.264 video and AAC audio. Every phone, browser, smart TV and editing app released in the last decade plays that combination, and most upload forms expect it.
Does converting a video reduce its quality?
Any re-encode is lossy, but at the default Quality (CRF) of 23 the difference is hard to see at normal viewing size. Use 18 when the result will be edited again, and avoid converting the same file back and forth, since each pass loses a little more detail.
Can this converter make a video smaller at the same time?
Yes. Lower the Resolution, raise the CRF value, or turn on Limit file size and type a maximum such as 10 MB. When the size is the only goal, compress video gives you more control, including two-pass encoding.
How do I convert a PowerPoint or a still picture into a video?
Upload the .pptx, .ppt or image file and choose MP4. Each slide or picture stays on screen for the number of seconds set in Seconds per slide, five by default. To put a picture behind a song, audio to video is the better fit.
Why is there no Video codec option when I pick WebM, AVI or GIF?
Those formats fix their own codec choice. WebM only allows VP8, VP9 or AV1, GIF is its own image format, and AVI output uses the codec the format expects, so the menu only appears for MP4, MOV, MKV and M4V, where several codecs are valid.
Will subtitles and chapters inside an MKV survive the conversion?
Do not count on it. The converter focuses on the picture and the main sound track, and formats like MP4 accept far fewer subtitle types than MKV. Keep the original file if its subtitle tracks matter, or export them separately with a subtitle tool first.
