How PixelKit Works

PixelKit harnesses standard browser APIs to edit images directly on your device without any backend servers.

1. Local Decoding

When you pick a file, your browser decodes the image bytes into a local HTML5 canvas. The image never leaves your device.

2. Hardware Acceleration

Compression, bicubic resampling, and pixel adjustments run through your phone or computer's GPU canvas pipeline for instant results.

3. Instant Direct Download

Your final image is packaged into a local Blob URL and downloaded directly to your phone's gallery or computer downloads.

Zero-Upload Privacy Policy

Traditional online image tools upload your personal photos to their cloud servers, exposing sensitive family pictures, documents, and IDs to data breaches.

No Server Uploads

PixelKit has no backend server or cloud database. 100% of image manipulation happens locally in your browser memory.

No Tracking or AI Training

We never inspect, store, or feed your photos to AI training sets. When you close the browser tab, your image data is wiped from RAM.

Safe Memory Management

Memory thresholds are strictly guarded at 20 MB and 8192px to prevent budget mobile devices from crashing during processing.

Frequently Asked Questions

Yes! PixelKit is built mobile-first. Tapping the upload box opens your phone's photo gallery or camera roll directly, and large 44px+ touch targets and directional nudge buttons ensure comfortable one-handed mobile editing.
PNG is a lossless image format. In browser canvas implementations, the quality parameter applies to lossy formats like WebP and JPEG. If you need substantial file size reduction, convert to WebP or JPEG.
PixelKit safely supports files up to 20 MB and up to 8192×8192 pixels. This prevents low-RAM mobile devices from running out of memory.
