Why is compression so fast?

Dedicated Infrastructure

We run our own servers in the European Union and control the entire stack—no third-party processing APIs, no "black box" cloud services in the hot path. This lets us tune everything end-to-end for compression workloads.

Our servers are provisioned with fast NVMe storage and optimised for parallel processing. Files never leave our infrastructure during compression.

Best-in-Class Compression

We don't reinvent the wheel. Each format uses industry-leading compression techniques:

• JPG — State-of-the-art lossy compression for optimal size with no visible quality loss
• PNG — Advanced lossless optimization for maximum compression
• WebP — Optimized encoding with tuned quality settings
• AVIF — Next-generation AV1-based compression optimized for still images
• PDF — Professional-grade compression with custom profiles for different use cases

Our compression engines are compiled with aggressive optimizations and SIMD instructions enabled. The result: compression that's faster than what you'd get running tools locally on most machines.

Pre-warmed Workers

Cold starts kill latency. Our worker processes are pre-warmed and ready to compress files immediately. There's no container spin-up, no library loading, no JIT compilation—just instant processing.

Workers are pooled per format type, so a PNG compression doesn't wait behind a slow PDF job.

Fair Scheduler

Our fair scheduler prevents any single user from monopolising workers. Jobs are distributed by tier (Business, Pro, Free) and then round-robin within each tier. If you upload 100 files, you get your share of workers while leaving capacity for others.

Paid users get priority access, but free users still get responsive processing during normal load. During peak times, Business accounts experience minimal queue delays.

Streaming Uploads

Files stream directly to our servers as you drop them—we don't wait for the entire upload to complete before starting validation. Large batches begin processing while you're still uploading the last files.
