Secure Client-Side Processing

Traditional image optimization sites require uploading your files to their external servers. This slows down your operations and introduces serious privacy, ownership, and interception issues.

PixelConvert solves this by running the entire conversion and compression pipeline directly in your browser tab, using the Canvas API and Web Workers (plus a WebAssembly decoder for HEIC files). Processing occurs 100% on your device — private screenshots, financial photos, and confidential images remain fully private.

High-Performance Batch Pipelines

Our batch pipeline lets you select dozens of images at once. Using background threads (Web Workers), files encode in parallel without blocking the UI.

Configure target formats, downscale heights and widths, and customize exact quality thresholds. Once completed, download individually or pack everything into a unified ZIP file in milliseconds.

Frequently Asked Questions

How does local browser processing work?

We use the HTML5 Canvas API and Web Workers to decode, resize, and compress your photos directly on your computer's CPU and RAM (HEIC files additionally use a WebAssembly decoder on browsers without native HEIC support). Your browser does 100% of the heavy lifting locally.

Are my personal files completely secure?

Yes, absolutely. Because we do not run a file-processing server, your images never leave your machine. There are zero remote API uploads, meaning your photos cannot be cached, intercepted, or leaked.

Can I process multiple images in a single batch?

Yes! You can drag and drop dozens of files simultaneously. Our engine processes them concurrently using separate Web Worker threads, which ensures your browser tab stays responsive and fast.

Does converting or compressing add watermarks?

No. All conversions, compression operations, and resizes are completely free, unlimited, and free of any watermarks, branding, or quality blocks.
