Complete File Compression Toolkit

AllToolsHub's file compressor suite offers 8 powerful compression tools, all running entirely in your browser. Our Video Compressor reduces MP4, WebM, and MOV file sizes by adjusting quality, resolution, and codec settings. The MP3 Compressor and WAV Compressor optimize audio files by adjusting bitrate and sample rate while maintaining listening quality.

For images, choose from our general Image Compressor (supports all formats), dedicated JPEG Compressor for photos, or PNG Compressor for graphics with transparency. Each offers quality controls, resizing options, and batch processing support.

The PDF Compressor reduces document file sizes by optimizing embedded images, perfect for email attachments. Our GIF Compressor shrinks animated GIFs through color reduction, lossy optimization, and scaling - ideal for web and social media sharing.

All tools are 100% free, require no signup, and process files entirely in your browser for maximum privacy. Your files are never uploaded to any server.

Free Online File Compressor - Compress Video, Images, Audio, and PDFs

Large files consume storage space, slow down websites, and create problems when sharing via email or messaging apps. AllToolsHub File Compressor brings together 8 compression tools for different file types: video compressor, MP3 compressor, WAV compressor, image compressor (JPEG, PNG), PDF compressor, and GIF compressor. All compression happens in your browser for maximum speed and privacy.

Video and Audio Compression

Video files are often the largest files on your device. Our video compressor uses FFmpeg WebAssembly to re-encode videos with optimized settings, typically achieving 40-70% file size reduction. Audio compression for MP3 and WAV files reduces file sizes by adjusting bitrate and encoding parameters while maintaining acceptable listening quality for music, podcasts, and voice recordings.

Image and PDF Compression

Image compression reduces file sizes for JPEG, PNG, and GIF files through quality optimization and metadata removal. JPEG compression adjusts the quality factor, PNG uses palette optimization and deflate compression, and GIF optimization reduces the color palette and applies frame differencing. PDF compression optimizes the internal structure and recompresses embedded content to reduce file size.

Privacy-First Compression

All compression happens locally in your browser. Your files including sensitive documents, personal photos, and private videos are never uploaded to any server. This makes our compressor safe for business documents, financial records, and any other sensitive content that needs file size reduction.

Frequently Asked Questions

What file types can I compress?

Video (MP4, WebM), Audio (MP3, WAV), Images (JPEG, PNG, GIF), and PDF documents.

How much compression can I expect?

Typical reductions: Video 40-70%, Images 30-60%, Audio 30-50%, PDF 20-60%. Results vary by content and original encoding.

Does compression reduce quality?

Some quality reduction is expected with lossy compression. Our tools use optimized settings to minimize visible quality loss while maximizing file size reduction.

Is batch compression supported?

Most compression tools support processing multiple files at once for efficient workflow.

Are my files uploaded?

No. All compression happens in your browser using WebAssembly and JavaScript. Your files never leave your device.

Is there a file size limit?

Limits depend on your device memory. Most modern devices handle files up to several hundred MB.
