Trim Audio
Cut the silence, the intro or anything else off a recording or a song, using its waveform.
Trim Audio keeps the part of a recording or song you want: cut a long silence, an intro or the chatter before a talk begins, or make a short clip for a ringtone or a message.
Almost any file
Images, vector art, video, audio, documents, spreadsheets, slides, ebooks and archives: more than 400 conversions. Before anything runs, Filebender says what a conversion will lose and estimates the size of video, audio and many pictures; other files show their size once converted. It compresses PDFs, pictures and videos to the size you choose.
No ads, no watermarks
With a free account: 20 files a day, 2 of them videos, each up to 500 MB. No plan has ads, and nothing is stamped on your files. A pass is one payment that never renews, and one you haven't used can be refunded in full.
Private by default
Files are deleted an hour after converting, or at once when you ask, and photo location is removed unless you choose to keep it. Photos converted to JPG, PNG or WebP are done on your device when your browser can, so they never leave it. They still need your account and count towards your plan.
How to trim audio
- Create a free account with Google or your email address, or sign in.
- Choose your files: drop them on the box, pick them from your computer, open them from Google Drive, or paste a link.
- Drag the handles on the timeline, or type the start and end times, to choose the part to keep. “Play the part” lets you check it first.
- Press “Trim”, then download each file, or all of them in one ZIP.
Using the waveform
The timeline draws the sound as a waveform, so quiet stretches and loud moments are easy to spot. Drag the handles, nudge them with the arrow keys a tenth of a second at a time, or type the start and end. “Play the part” plays your selection first.
Very large files, ones your browser can't read, and ones from Google Drive or a link get a plain timeline that works the same way.
Formats and quality
MP3, WAV, AAC, FLAC, OGG and OPUS are trimmed into the same format; M4A, WMA and AIFF need a new one, such as MP3 or AAC. Lossy formats are encoded again at the audio bitrate in the settings, 128 kbps unless you change it, so raise it to match a high-quality original, 320 kbps for instance. FLAC loses nothing. WAV is written as 16-bit, which keeps a 16-bit recording as it was but reduces a 24-bit one.
How it counts
A trimmed recording counts as one ordinary file: with a free account you can convert 20 a day, each up to 500 MB, and with a pass files up to 2 GB. The trim runs on Filebender's servers, and files are deleted an hour after converting.

Questions
How precise is the cut?
To a tenth of a second. The part you keep is encoded afresh, so the cut falls where you put it.
Can I fade in or out?
No. Filebender cuts cleanly at the times you choose, without fades, so start and end in a quiet moment to avoid a click.
Can I trim the sound from a video?
Yes. Add the video, trim it, and choose MP3 or another audio format; it counts as an ordinary file, not a video.
Is the cut exact?
Yes, to a tenth of a second. The part you keep is encoded again, so the cut doesn't have to fall on a keyframe the way a quick copy would. That's also why trimming a long file takes a little while.
Is Filebender free?
Yes, with a free account: 20 files every day (up to 2 of them videos), each up to 500 MB, with no watermark and no ads. Make the account with Google or your email address. Files converted on your device count the same way as the rest. If you need more, a Day, Week or Month Pass is one payment that never renews; see the Pricing page.
What happens to my files?
It depends on the file. Pictures your browser can convert itself, and everything you do with the PDF tools, from merging and splitting PDFs to putting photos into one, are handled on your device and never leave it, unless you choose to send a file to Filebender's servers. They still need your account: Filebender receives only their type and size, to count them against your plan like any other file. Everything else is converted on Filebender's servers on Google Cloud and deleted an hour after the conversion finishes, or straight away when you press “Delete files now”. Nobody looks at your files, and they're never used for anything else.
