OneImage Resize by 王军

OneImage Resize packs the essential resizing tools from resize.oneimage.co into a streamlined browser popup. Drop any image, set exact dimensions or scale by percentage, and export a resized copy without leaving your current tab. The workflow stays entirely on-device so client assets and screenshots never upload.
Toggle aspect ratio lock, preview output size, and compare before downloading. When you need batch presets, smart format conversion, or automation, continue straight into the full OneImage studio.

Key Features
- Local, offline resizing — no accounts, uploads, or telemetry.
- Drag & drop, paste, or browse for PNG, JPG, WebP, AVIF, and more (up to 12k px).
- Two modes: exact dimensions with optional aspect lock, or percentage scaling from 10–400%.
- Live dimension + file size preview for the resized output.
- Automatic export naming based on width × height.
- Immediate download plus shortcut to the full web editor.
- Polished UI built for quick single-image adjustments.

How It Works
- The extension renders your image to an HTML canvas, applies the chosen dimensions or scale factor, and re-encodes using the original format (JPEG quality tuned automatically). Processing and downloads stay in memory on your device.
