Online MP3 Sıkıştırma

What MP3 Sıkıştırma does

Audio compression here means saving the same recording with less data. For MP3 files, MP3 Sıkıştırma re-encodes the sound with the LAME encoder at a lower bitrate. For WAV files, the result stays an uncompressed WAV, and the size goes down by lowering the sample rate, the number of channels or the bit depth.

Each of these steps removes information, so the aim is to remove only what listeners will not miss. Typical targets are voice notes, podcasts, lectures and sound effects that must fit an upload or email limit.

MP3 Sıkıştırma nasıl kullanılır

1. Küçültmek istediğiniz dosyaları bırakın.
2. Bir sıkıştırma seviyesi seçin veya önerilen ayarı kullanın.
3. Sıkıştır'a tıklayın ve eski ile yeni dosya boyutlarını karşılaştırın.
4. Küçültülmüş dosyaları indirin.

When to use MP3 Sıkıştırma

• Make a long podcast or lecture MP3 small enough to send by email or post on a site with an upload limit.
• Reduce WAV voice recordings from a field recorder before archiving hundreds of interviews on a shared drive.
• Prepare short WAV sound effects at 22050 Hz mono for a game, an app or a device with little memory.
• Shrink an audiobook chapter to 64 kbps mono so it takes less space on a phone or an old MP3 player.

Settings explained

Bitrate

For MP3 files, sets the new bitrate from 32 to 160 kbps. The default of 96 kbps is clear for speech. Use 128 or 160 kbps for music, and 32 or 48 kbps only for voice.

Mono

Mixes left and right into one channel. For WAV files it is on by default and halves the size. For MP3 files it is off by default and makes speech clearer at low bitrates.

Sample rate

For WAV files, sets how many samples are stored per second. 44100 Hz is CD quality, the default of 22050 Hz is fine for speech, and 8000 Hz sounds like a telephone line.

Bit depth

For WAV files, chooses 16-bit or 8-bit samples. 16-bit, the default, sounds clean. 8-bit halves the size again but adds audible hiss, so use it only for simple sound effects or retro projects.

MP3 nedir?

MP3 (MPEG-1 Audio Layer III), Fraunhofer IIS tarafından 1993 yılında tanıtılan bir ses formatıdır. Bu format kayıplı sıkıştırma kullanır. Dosya uzantısı: .mp3.

MP3 is audio layer III of the MPEG-1 and MPEG-2 standards, developed mainly at the Fraunhofer Institute in Germany. It uses a model of human hearing to remove sounds that most listeners cannot hear, which made music files about ten times smaller than CD audio. Its patents have now expired.

MP3 is the best choice when an audio file must play on every possible device, for example podcasts, music collections, audiobooks and voice recordings shared with many people. A bitrate of 192 to 320 kbps suits music well.

MP3 is less efficient than AAC or Opus, so it needs a higher bitrate for the same quality. At low bitrates, cymbals and high tones can sound watery. Converting from one lossy format to another always loses some quality.

MP3 plays in all web browsers, on Windows, macOS, Linux, Android and iOS, and on car stereos, smart speakers, TVs and older portable players. It is the most widely supported audio format.

Tips for the best result

• WAV sizes are easy to predict: 44100 Hz stereo 16-bit uses about 10.6 MB per minute, and 22050 Hz mono 16-bit uses about 2.6 MB.
• If you need much smaller audio than WAV allows, convert to MP3, M4A or OPUS with the audio converter instead. Lossy formats are far more efficient.
• Compressing an MP3 that already has a low bitrate rarely helps. If the result would be larger than the original, you get the original file back.
• Listen to part of the result before deleting anything, and keep the original recording in case you need higher quality later.

How MP3 Sıkıştırma works in your browser

Video and audio are processed with FFmpeg, the open-source media toolkit behind most video software, compiled to WebAssembly. Video is encoded with H.264 for MP4, MOV and MKV, VP8 for WebM, and audio with AAC, MP3, Vorbis, Opus or FLAC depending on the format.

WebAssembly FFmpeg runs on your device's processor without a server. It is slower than a native desktop app, so a long video can take a few minutes. Keep the tab open until the progress bar finishes.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. MP3 Sıkıştırma works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
