How It Works

Compress any file in 3 steps

Choose your file

Drag and drop your file onto the tool, or tap to browse your device's storage. Works on Android, iPhone and desktop.

Pick your settings

Select quality level and output resolution. Lower settings give the smallest file — higher settings keep more detail.

Download the result

Compression runs on your device in seconds. Download the smaller file directly — no waiting, no email, no signup.

Why CompressAll

Built for privacy and speed

Most online tools upload your files to a server. CompressAll works differently.

🔒

No waiting in queue
Browser-based processing means instant start. No server queue, no upload time, no download delays from a remote server.
📱
Works on any device
Tested on Android Chrome, iPhone Safari and desktop browsers. Compress files directly from your phone camera roll.
Always free
No file size limit hidden behind a paywall. No watermark on output. No account needed. Free for everyone, forever.

The best free online file compressor — no upload required

CompressAll is a browser-based file compression tool that lets you reduce the size of video, image and PDF files without uploading them to any server. All processing happens locally on your device using FFmpeg WebAssembly and the Canvas API, which means your files are always private and compression starts instantly with no waiting.

Why compress files online?

Large files are slow to share and take up unnecessary storage space. WhatsApp has a 16MB file limit, most email services cap attachments at 25MB, and websites load faster when images are optimized. Compressing your files before sharing saves time for both you and the person receiving them.

Compress video online free

Our video compressor supports MP4, MOV, MKV, AVI and WebM formats. You can choose the output resolution from 360p to 1080p, adjust quality with a simple slider, and get a compressed MP4 file ready for WhatsApp, email or social media. The tool works on Android and iPhone as well as desktop computers.

Compress images online without losing quality

The image compressor reduces JPG, PNG and WebP file sizes using smart lossy and lossless algorithms. You control the quality level — high quality for photos you want to keep sharp, lower quality for images shared on social media where file size matters more than perfect detail.

Is it really free with no limits?

Yes. CompressAll has no hidden file size limit, no watermark on compressed files, and no account requirement. The tools are supported by non-intrusive advertising, which keeps everything free for users. There are no premium tiers that restrict compression quality or file size.
