Percentage Image Resizer

Scale each image by a percentage of its original dimensions.

Choose the percentage and review both output dimensions. Use the original again when comparing another setting.

How to use

Choose a static JPEG, PNG or WebP source. Check the displayed upload limits before processing.

Why use this tool

One percentage keeps the same proportions across each supported image in the batch.

Before relying on the result

Compare the finished picture with its source. Halving both dimensions gives roughly one quarter of the original pixel area.

Questions

Does 50% mean half the pixel count?
