The Batch Image Resizer is a client-side image processing utility that scales graphics, photos, and web banners by exact dimensions or proportional percentages. Utilizing the browser's hardware-accelerated Canvas 2D API with bicubic interpolation, it adjusts image resolution while preserving aspect ratios and protecting privacy.
Downscaling preserves crisp details using browser bicubic smoothing. Upscaling beyond original dimensions naturally has diminishing returns as missing pixels must be interpolated.
No. All pixel resampling takes place directly on your computer or mobile device using HTML5 Canvas. Your photos never leave your device.
The resizer supports all major web formats including JPEG, PNG, WebP, GIF, BMP, and SVG.
There are no arbitrary server upload limits. The only constraint is your device's available RAM to hold the canvas bitmap in memory.
