About the Audio Waveform Image Maker
A waveform picture shows the loudness of a sound over time, and it makes a striking image for podcasts, music covers, wedding vows, voice messages and posters. Drop an audio file, choose a style (bars, centred bars or fine lines), the picture size, the colour of the wave and the background, or tick transparent to place it over your own design, and download a PNG. The look updates as you change the settings. The audio is read and drawn in your browser, so recordings, such as private messages, are not uploaded anywhere. The picture is a smoothed view of the peaks, not an exact plot of every sample.

Design ideas
For a podcast cover or a social post, choose the square or story size, a bold colour on a dark background and between 60 and 120 bars. For a gift, such as a wedding vow or a baby's first words, use a transparent wave in a colour that fits the frame and print it on a canvas or card.
Fewer, wider bars look bold and graphic. More, thinner bars look refined and show more detail of the speech or music.
Export size matters for sharing. The wide and banner sizes suit website headers and video thumbnails, the square size is right for social posts and album art, and the story size fits phone screens in portrait mode. The picture is drawn at full size, so it stays sharp when you place it on a design that is printed or shown on a large screen.
Tips
- Trim the audio first so that the wave shows only the part you want.
- Use high contrast between the wave and the background.
- Add the title or date in a design tool after downloading.
- Try the fine lines style for a technical look.
- Keep a transparent version for use on any background.

Cut the audio to the right part with the Audio Trimmer, record a message with the Voice Recorder and check the sound with the Mic Test. For a poster add text with Add Text to Image, and to lay out several pictures use the Collage Maker. A waveform is a lovely way to remember a sound.

Frequently asked questions
What does the picture show?
Each bar or line is the loudest point in a short stretch of the audio, so the whole width of the picture covers the whole length of the file, from left to right.
How can I use a transparent waveform?
Tick Transparent background and download the PNG. Place it over a photo or design in any graphics or video editor.
Which style should I choose?
Centred bars look balanced and are popular for voice and podcasts. Fine lines look detailed, as in audio editors. Bars rising from the bottom suit a music player look.
Can I make a long track look good?
Yes. The picture always shows the whole file. For a chosen part, trim the audio first.
Why is my waveform very flat?
The recording may be very quiet or have one very loud spike. The picture is scaled to the loudest point, so a spike makes the rest look small.
Is the picture exact?
It is a summary of the peaks, good for looks. It is not meant for measuring.
Is my audio uploaded?
No.
