Image Resizer (Batch)
Resize up to 50 images at once — by percent, width, height or exact size

Preguntas frecuentes
Will resizing reduce my image quality?⌄
Downscaling uses high-quality smoothing and generally looks great. Upscaling beyond 100% cannot invent detail — it gets softer the further you go. The quality slider controls JPEG/WebP compression on export.
What does exact mode do differently?⌄
Percentage/width/height modes always preserve the aspect ratio, so nothing looks stretched. Exact mode applies both dimensions literally — useful for thumbnails or fixed slots, but it can distort the picture.
Are my photos uploaded to a server?⌄
No. Decoding, resizing and re-encoding all happen in your browser with the canvas API. Files never leave your device.
