File workflow
File size basics
Large files are not always bad. They often contain more audio detail, more pixels, a longer duration, or less compression. The question is whether that extra data is useful for the task in front of you.
Why audio files get large
Audio size depends on duration, sample rate, bit depth, channels, and compression. A long stereo WAV file can be very large because it is often uncompressed. An MP3 can be much smaller because it stores a compressed version.
Why image files get large
Image size depends on pixel dimensions, format, color detail, transparency, and compression quality. A high-resolution phone photo may have far more pixels than a blog post or form upload needs.
Which action should you choose?
- Compress audio: lower MP3 bitrate to reduce size.
- Trim audio: remove time you do not need.
- Resize image: reduce pixel dimensions.
- Compress image: reduce saved image weight while keeping dimensions.
- Convert format: use a format the destination accepts.
