Frequently Asked Questions

Will resizing reduce image quality?

Reducing dimensions always involves some trade-off, but for normal web use the difference is invisible to the human eye. You can control the output quality level — we recommend 80–85% for the best balance of size and sharpness.

Can I reduce images to specific pixel dimensions?

Yes. Enter an exact width and height, or just one dimension and let the tool maintain the aspect ratio automatically.

How many images can I resize at once?

There's no hard limit on the number of images. Upload as many as you need in one session.

What's the maximum file size per image?

Each image can be up to 25MB. Most phone photos and downloaded images are well under this.

What image formats are supported?

The tool supports JPG, PNG, WebP, and GIF files. You can mix formats in the same batch — upload some JPGs and some PNGs together and resize them all at once.

Can I download all resized images together?

Yes. The Download ZIP button bundles every completed image into a single archive. You can also download individual files by clicking the download icon next to any image.

Is this Bulk Resizer Tool really free?

Yes, completely free. No hidden fees, no watermarks, no usage limits, no account required.

Does the tool stretch my images if I enter exact dimensions?

Exact size mode does force every image to the width and height you specify, which can stretch images whose original proportions don't match. If you want to keep the aspect ratio intact, use the Fit within bounds mode instead, which scales images proportionally within your maximum dimensions.

Does the tool store or upload my images?

No. Everything happens locally in your browser. Your images are never sent to any server, stored, or shared — they stay on your device the entire time.
