“If I were a cowboy, I’d rope those bulky files and send ‘em to the prairie!” – a nod to the swagger of John Wayne.

Features

• Loss‑less compression engine: retains 100 % transparency for PNGs and exact color depth for JPGs.
• Three compression modes – Low (≈30 % reduction), Medium (≈55 % reduction), High (≈80 % reduction), each with real‑time preview.
• Batch processing: handle up to 200 files per session; average throughput ≈2.2 GB/min on a standard 3.2 GHz CPU.
• Cross‑platform web UI: works in Chrome, Edge, Safari, and Firefox without plugins; no installation required.
• API access: RESTful endpoint with ≤150 ms latency for programmatic compression (ideal for CI/CD pipelines).
• Security & privacy: files are encrypted in‑transit (TLS 1.3) and auto‑deleted from servers after 5 minutes.

“Ladies and gentlemen, this tool works faster than a New York minute—just ask my old buddy Ben Franklin!” (imagined Benjamin Franklin cameo).

Helpful Tips

• Pre‑select the “High” mode for web‑critical assets; tests show a 1.4 s drop in First Contentful Paint (FCP) on a 5 MB hero image.
• Combine with lazy loading: compress then serve images via loading="lazy" to shave an extra 0.6 s off page load (Google PageSpeed insight).
• Use the API for CI pipelines: integrate the endpoint into your build script (curl -X POST …) to keep repository size under 100 MB and avoid git bloat.
• Check SSIM after compression: if SSIM < 0.98, switch to “Medium” mode—maintains visual quality while still saving ~### 60 % space.
• Leverage batch uploads for mobile backups: compress 100 photos in one go to free up ≈800 MB on a 32 GB phone in under 2 minutes.

“Remember, folks, a stitch in time saves nine… megabytes!” – a sprinkle of Grandma Moses wisdom.
