About this tool
Width is set to 1080 px with aspect ratio locked. 1080 px is a common width for social platforms and phone screens, giving smaller, faster images without distortion.
Resize images in bulk by pixels or percentage, with or without keeping the aspect ratio. High-quality Pica resampling keeps downscaled images sharp, and processing can be cancelled at any time.
How to use
Upload images, choose pixels or percentage and a resampling method, and set aspect-ratio behavior.
Process, check dimensions and sizes, then download files individually or as a ZIP.
For example, set a 2,400 px wide image to 1,200 px wide and leave height blank to keep its aspect ratio. With both dimensions, the image fits inside the box by default; disable aspect ratio to use those exact dimensions.
Pica resampling can be cancelled. With aspect ratio enabled, width and height define a bounding box; disabling it allows stretching. Input/output: up to 45 MP and 16384 px per side.
Choose Pica resampling or a faster browser resize. Input/output is capped at 45 MP and 16384 px per side. Use Image cropper to keep only part of the image.
Frequently asked questions
How is the height calculated?
With aspect ratio on, height follows the original proportions automatically.
What if my image is smaller than 1080 px?
It is scaled up to 1080 px, which adds no detail; use larger originals if you only want to downscale.
How are width and height used with aspect ratio on?
They form a bounding box; each image scales proportionally to fit inside it without distortion. Turn the option off to stretch to exact dimensions.
