Bulk Image Resizer FAQ

How do I resize multiple images at once?

Select multiple image files using the upload area, choose the target dimensions and output format, then select Process All Images. The tool processes the selected images in your browser.

How many images can I resize at once?

You can select multiple images in one batch. Each image is limited to 5 MB in the current tool. Very large batches may use more browser memory, so smaller batches can be better on phones and devices with limited memory.

Can I keep the original aspect ratio?

Yes. Keep Maintain Aspect Ratio enabled to fit each image within the selected width and height without stretching it. The output canvas uses the dimensions you choose.

Which image formats are supported?

The current tool accepts JPEG, PNG and WebP images and can produce JPEG, PNG or WebP output. Animated GIF files are not supported by this version.

Can I download all resized images together?

Yes. After processing, select Download All as ZIP. The tool creates a ZIP file containing the processed images so you can download the batch together.

Are my images uploaded to a server?

The resizing process is performed in your browser using client-side image processing. The page does not need to upload the image files to a ResizeHero server for the resize operation.

Will resizing reduce image quality?

The result depends on the original image, output dimensions and selected format. JPEG and WebP output can use lossy encoding, while PNG uses lossless encoding. Resizing an image to smaller dimensions can also remove image detail.
