Practical, tool-agnostic explanations of the media jobs people actually do: cutting, joining, converting, cleaning up and recording.
- How to trim an MP3 without making it worseCut the start or end off an MP3 while keeping the original quality, and understand why some tools make the file bigger.
- How to merge audio files so the joins are invisibleCombine MP3s, WAVs or mixed formats into one track, handle different sample rates and volumes, and choose the right crossfade.
- WAV to MP3: which bitrate, and when not to convert at allTurn uncompressed WAV into MP3 without guessing. Bitrate, CBR vs VBR, sample rate, tags, and the cases where you should keep the WAV.
- How to extract audio from a video without re-encodingPull the soundtrack out of an MP4, MOV, WebM or MKV in seconds by copying the audio track, and know when converting to MP3 is actually worth it.
- How to remove background noise from a recordingFan hum, room tone, traffic and keyboard clatter each need a different fix. What neural noise suppression does well, what it cannot fix, and how to record so you need less of it.
- How to record audio in your browser and get a clean takeMicrophone permissions, levels, mono versus stereo, which format to save, and how to trim the silence — everything between pressing record and having a file you can use.
- How to compress a video without wrecking the pictureShrink an MP4, MOV or WebM by bitrate, resolution and frame rate — and know when a target file size is a better ask than a quality slider.
- How to convert a video without guessing the settingsTurn MOV, WebM, MKV or an older camera file into an MP4 (or GIF, or audio) with a destination preset, a trim, and an honest note about when the file leaves the browser.
- How to crop an image and keep the subject in the frameDraw a crop box, lock an aspect ratio, and export PNG, JPEG or WebP — without the picture sliding out from under the handles.
- How to merge PDFs so the pages stay in the right orderCombine several PDFs in the browser, drag the file order from first-page thumbnails, and keep each document's pages intact.
- How to compress a PDF without turning the text into a photoTry a lossless re-save first. Only rasterise pages to JPEG when the file is still too large — and know that text then becomes an image.
- How to make a GIF from a video that is still watchableTrim the moment, cap width and frame rate, and understand why a GIF is a cartoon of the clip — not a second video file.
