Resize Images

Resizing images should be a simple operation, yet most online tools insist on uploading your photos to their servers first. This creates unnecessary privacy exposure, especially when dealing with personal photographs, identity documents, or proprietary visual assets. LocalForge performs all image resizing entirely within your browser. The pixels on your screen are processed by your own hardware, and the resized result is generated locally.

The resize engine uses the Canvas API and high-quality interpolation algorithms to scale images up or down while preserving sharpness and color accuracy. You can specify exact pixel dimensions, scale by percentage, or fit within a maximum boundary while maintaining aspect ratio. The processing runs in a dedicated Web Worker thread, keeping the interface responsive during large batch operations.

This client-side approach is particularly valuable for professionals handling confidential imagery. Photographers working with unreleased client photos, medical professionals dealing with patient imaging, and legal teams processing evidentiary photographs all benefit from guaranteed local processing. No server logs record your filenames, no cloud storage retains your originals, and no third-party terms of service claim rights over your content.

LocalForge supports JPEG, PNG, WebP, and BMP inputs with configurable output quality. Resize a single image or process an entire folder at once. Your images stay yours throughout the entire workflow.
