Image exports are still images. PNG preserves transparency; JPG uses a solid background. Large files and batches depend on your device memory. Always preview important results before sharing.
About Bulk Image Resizer
Give a batch of images a consistent width or scale them by the same percentage. Keeping the aspect ratio lets differently shaped originals retain their proportions; use a fixed canvas when every output must have identical dimensions.
How to use this tool
01 · Prepare your input
Choose your images from the device. Keep the batch within 50 files and 40 million pixels in total.
02 · Set the new dimensions
Choose pixels or percentage. Keep the aspect ratio, or unlock it and select stretch, fit with padding or fill and crop.
03 · Review the result
Resize, check the pixel dimensions and preview, then download the image. Batch results are also available as a ZIP.

What to know about Bulk Image Resizer.
How can I resize without stretching the picture?
Keep the aspect ratio enabled, or use fit with padding for a fixed canvas. Fill and crop also preserves proportions but removes some edges.
Are my files uploaded for processing?
No. File contents are processed in your browser. The site, codecs and any required models still need to load over the network; local results depend on your device and browser.
