Python Pillow Backend
Server-side compression using Pillow's true lossless WebP encoder with quality=100 and lossless=True. SHA-256 pixel hash verification ensures bit-for-bit fidelity.
Lossless Guarantee
Every pixel is preserved exactly. The compressed image is mathematically identical to the original — verified by comparing SHA-256 hashes of raw pixel data before and after compression.
Instant Processing
Vercel serverless functions process your image in milliseconds. No queues, no waiting. The compressed file is ready for immediate download.
