HOW IT WORKS

From your file to the result
in three steps

The converter runs on this page. There is no upload to wait for, so large files start right away.

01

Drop in your file.

Drag a video or audio file onto the converter, or click to choose one. MP4, MOV, M4V, MKV, WebM, MP3, WAV, M4A, FLAC and OGG are supported.

02

Pick a format or size.

Choose MP3, M4A or WAV to extract audio, or pick a target size such as 10 MB to compress a video.

03

Download the result.

Your browser does the work using your computer’s own encoder. When it finishes, click Download. The original file is untouched.

PRIVATE BY DESIGN

An online tool
that keeps your files.

Unreleased tracks, client interviews, family videos. Most online converters upload them to a server. ConvertRight converts them inside your browser, so they never leave your device.

No uploads

Conversion runs on your device, not on our servers.

Keep your originals

You get a new file. Your source stays as it was.

No waiting in a queue

Speed depends on your computer, not on how busy a server is.

Online, without
the upload.

Upload-based converters send your file to a server and back. ConvertRight skips that step.

Online converter

Is ConvertRight a free online converter?

Yes. Convert or compress files up to 100 MB each for free, with no account and no watermark. ConvertRight Pro removes the size limit for $4.99 a month and can be canceled anytime.

Are my files uploaded to a server?

No. ConvertRight runs inside your browser. The file is read and converted on your own device, and the result is saved straight to your downloads. We never receive your media.

How do I convert MP4 to MP3 online?

Drop your MP4 into the converter, choose MP3 and click Convert. When it finishes, click Download. MP4, MOV, M4V, MKV and WebM videos are supported, and you can also choose M4A or WAV.

How do I compress a video to a specific size?

Choose Compress video, drop in your file, pick 10, 25, 50 or 100 MB or type your own size, then click Compress. ConvertRight sets the bitrate from the video's length and lowers the resolution when needed so the MP4 fits the size you chose.

Which browsers work?

Recent versions of Chrome, Edge, Safari and Firefox on desktop. Chrome and Edge are usually fastest because they use your computer's hardware video encoder. Phones work for small files, but large videos are better on a computer.

Why is there a 100 MB limit on the free plan?

Free use covers most clips you want to share or turn into audio. Pro is for people who regularly handle long recordings or large videos, and it keeps the site free of ads for everyone else.

Can I paste a YouTube or TikTok link?

No. ConvertRight works with files already saved on your device that you own or have permission to use. It does not download videos from websites.

Is there still a desktop app?

Yes. The Mac and Windows app adds Finder right-click actions on Mac and works offline. It includes 5 free conversions, then costs $1 once per computer. It is sold separately from Pro.

Desktop app: audio

How do I convert MP4 to MP3?

On Windows, add your MP4 to ConvertRight, choose MP3 and click Convert. On macOS, right-click it in Finder and choose Extract audio as MP3. The output is saved beside the original.

How can I convert a downloaded YouTube video to MP3?

Start with a supported local video file that you own or have permission to use. On Windows, add it to ConvertRight, choose MP3 and click Convert. On Mac, right-click the file in Finder and choose Extract Audio As → MP3. The audio is saved beside the video. ConvertRight does not download YouTube videos or accept YouTube links.

How do I extract audio from a saved TikTok video?

If you have a supported TikTok video file saved on your computer and permission to use it, add it to ConvertRight on Windows or select it in Finder on Mac. Choose MP3, M4A or WAV to save a separate audio file beside the video. TikTok links cannot be converted directly.

Can I turn a video podcast or interview into an audio file?

Yes. Convert a supported local video podcast, interview or lecture to MP3 or M4A for listening, or WAV for editing. Conversion keeps the existing audio mix, including speech, background music and other sounds; it does not isolate speech or remove background music.

Can I extract audio from a video without uploading it?

Yes. MP4, MOV, M4V, MKV, WebM and AVI video-to-audio conversion runs locally on your computer. Your media is never uploaded for conversion.

Can I convert WAV to MP3?

Yes. In the Windows app, add the WAV file and choose MP3. On macOS, use Convert audio as MP3 in Finder. A separate MP3 is saved beside the original.

Can I try MP4 to MP3 conversion?

You can try audio conversion before purchasing. See the downloads and pricing section below for the included usage and license details.

Will converting MP4 to MP3 lose audio quality?

MP3 is a lossy format, so some quality loss is possible when audio is encoded as MP3. ConvertRight.APP uses a built-in MP3 setting and does not offer bitrate or sample-rate controls.

Where are my converted files saved?

Converted files are saved beside the original file. The original is preserved and is not overwritten.

Can I convert multiple files at once?

Yes. Select multiple supported media files in Finder, right-click, and choose an output format. ConvertRight.APP converts each file and saves the results beside the originals.

Desktop app: video

How can I compress a video locally on my PC?

Download ConvertRight for Windows, extract the ZIP and open ConvertRight.exe. Add a video, choose MP4, enter your target size and click Convert. Media is processed locally, and the compressed file is saved beside the original. On macOS, use Compress Video in Finder.

How can I compress a 4K video to 1080p?

On Windows, add your 4K video, select MP4 and Max 1080p, then choose a target size. On macOS, choose Compress Video → Custom Size and the maximum 1080p option. The output keeps its aspect ratio; portrait videos may have different dimensions.

How can I compress a video to a size of 2GB?

For a decimal 2 GB limit, enter 2000 MB as your custom target. ConvertRight checks that the completed video is below your selected limit. The achievable quality depends on duration and content. Keep enough free disk space for the source, temporary files and output.

What should I do if an MP4 file is too big?

Choose a smaller target size and, if appropriate, a maximum resolution of 1080p or 720p. You can also remove audio when it is unnecessary. ConvertRight creates a separate H.264 MP4 and preserves your original.

Does compressing video reduce quality?

Yes, lossy re-encoding can reduce detail. Lower bitrates and smaller resolutions can make the difference more visible, especially in fast movement or fine textures. Choose a larger target when quality matters and keep the original for editing.

How do I compress a large video without uploading it?

Use the desktop app to process a supported local MP4, MOV, M4V, MKV, WebM or AVI. Large videos need more time and free disk space. The Windows version currently accepts SDR video; export an SDR copy of HDR footage first. Processing is local; you do not need to upload the video to an online compressor.

How do I compress a video to 10 MB or 25 MB?

Set 10 MB or 25 MB as your target in the Windows app. On macOS, choose Under 10 MB or enter a custom size. If the selected target cannot produce a valid output, choose a larger size.

Can I compress a video for Discord or email?

Check the current upload or attachment limit for your account and use it as your target. ConvertRight saves a separate MP4 locally, ready for you to upload or attach.
