Frequently asked questions

Is the aspect ratio preserved?

Yes, all images keep their original ratio — nothing is ever stretched or cropped. Portrait and landscape photos in the same batch each keep their own ratio.

How many images can I process at once?

Up to 100 images per batch. All processing happens locally in your browser, so it takes longer with many large files — there is no server quota.

In what format are the results saved?

Each file is saved in the same format as the input: JPG stays JPG, PNG stays PNG. File names are preserved too; only the dimensions change.

What is bulk resize used for?

Popular for website management (all images to max 1200px wide), e-commerce (product photos to one size), shrinking holiday photos for email, and cleaning up photo libraries for storage.

Is my image uploaded?

No. Everything happens in your own browser. Your image never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.

Why in the browser?

PixRust runs entirely in your browser using the Canvas API and WebAssembly. Your image is never sent to a server — all processing happens locally on your device. This means your photos remain private by design, whether they are personal snapshots or confidential documents. There is no account required, no file size limit, and nothing is stored after you close the tab.
