Waveform Image

Waveform Image turns sound into a picture. Drop in a song, podcast episode, voice note or video and its waveform appears straight away, ready to style as bars, a mirrored reflection, a smooth line, dots or a circle of bars radiating outwards. Pick one of seven colour themes or your own colours, add a gradient, choose a background colour or leave it transparent, and set the bar width, gap and rounding to taste.

Sizes are ready for where the picture is going: square and portrait posts, stories and reels, a YouTube banner, an X or LinkedIn post, a slim strip for a website, or any custom size up to 4,000 pixels. Add a title, a subtitle and time labels in one of 18 fonts, show the whole recording or just one part, then download a PNG or a sharp, editable SVG.

For social media there is also an audiogram: a 15 to 60 second video of your design in which the waveform lights up as the sound plays, with a playhead and a running clock. Everything, including the video, is made in your browser.

1. Press “Choose a file” or drop an audio or video file on the box. The preview appears.
2. Under Look, pick a style, a Size and a colour theme, or set your own colours and background. Open “Bar shape and detail” for bar width, gap, rounding and margin.
3. Optionally type a Title and Subtitle, choose a font, and tick “Time labels”. Choose “Part” to show only a stretch of the recording.
4. Press Download PNG or Download SVG.
5. For a video, set “Clip starts at” and a clip length under Audiogram video, press “Listen to the clip” to check it, then press “Make video” and download it.

• Five styles: bars, mirrored bars with a reflection, line, dots and circle.
• Seven colour themes, any wave colour, two-colour gradients across or down, and a coloured or transparent background.
• Seven ready sizes for social posts, stories, banners and websites, plus custom sizes from 100 to 4,000 pixels.
• Adjustable bar width, gap, rounding and margin; bars from peaks or average loudness, stretched to full height or true to level.
• Title, subtitle and start and end time labels in 18 bundled fonts.
• Show the whole recording or any part of it, chosen by time.
• PNG download at full size, and SVG for crisp printing or editing in design software.
• Audiogram videos of 15, 30, 45 or 60 seconds with a played colour, playhead, clock and the sound, as MP4 or WebM.

• “Average loudness” gives a more varied, natural shape for speech; “Peaks” suits music with sharp drums.
• Untick “Stretch to full height” to compare quiet and loud recordings side by side at their true levels.
• For a website header, choose “Website strip”, a transparent background and the SVG download.
• SVG text uses the font if the viewing device has it, so for printing, export a PNG or convert the text to outlines in your design app.
• Videos are kept to Full HD on the long side so they encode quickly; a YouTube banner design becomes a 1920 × 1080 video.
