About MP4 and WAV
What is MP4?
MP4 is the universal video format. With H.264 video and AAC audio it plays on practically every device made in the last 15 years and is accepted by YouTube, Instagram, TikTok, WhatsApp and every editor. If you are not sure which format you need, you need MP4.
- Plays everywhere
- Good quality at small sizes
- Accepted by every platform
- Usually only one audio track and limited subtitle support
What is WAV?
WAV stores raw, uncompressed audio — exactly what a microphone or CD captured. That is ideal for recording and editing because nothing is lost, but a minute of CD-quality stereo takes about 10 MB, ten times more than an MP3.
- Perfect, uncompressed quality
- Supported by every audio editor
- Huge files
- Limited metadata (tags, cover art)
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Does converting MP4 to WAV keep the full audio quality?
WAV is uncompressed, so nothing is lost — but if the source is a lossy format (MP4 audio is usually AAC), the result cannot sound better than the original; it will only be bigger.
Is there a file size limit?
On the free plan each video or audio file can be up to 500 MB and each image up to 100 MB. With Pro the limit is 4 GB per file. Because everything happens on your device, the practical limit for very large files is your device’s memory.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
