Frequently Asked Questions
What audio file formats can I trim?
Flipper File's audio trimmer supports MP3, WAV, OGG, FLAC, M4A, and AAC files. Simply upload your file and the tool will detect the format automatically.
Does the output file keep the same format as the input?
Yes. If you upload an MP3, you'll download an MP3. If you upload a WAV, you'll get a WAV back. The trimmer does not convert between formats.
Is there a file size limit?
There is no hard file size limit enforced by Flipper File. However, very large files (1 GB+) may take longer to load since everything runs in your browser. For best performance, trim files under 500 MB.
How precise can I make my cut?
You can enter start and end timestamps down to the millisecond, giving you frame-accurate control over your clip. The waveform display also lets you visually position your cut points.
Does my audio file get uploaded to the internet?
No. The entire trimming process happens inside your browser using the Web Audio API. Your file is never sent to any server. This makes Flipper File's audio trimmer one of the most private options available online.
Can I use this to create a ringtone?
Yes. Trim any song or audio file down to 20–30 seconds, download the clip, and then use it as a ringtone. Most phones accept MP3 or M4A format for ringtones.
What happens if I upload the wrong file type?
The tool will display an error message and prompt you to upload a supported audio file. No harm is done — just try again with a compatible format.
Can I trim the same file multiple times to get multiple clips?
The tool trims one clip per session. To get multiple clips from the same file, simply reload the tool, upload the file again, and set a new start/end range for each clip you need.
