Image Resizer

No images selected. Choose files to get started.

Our free online image resizer lets you change the dimensions of any JPG, PNG, or WEBP image in seconds — right in your browser. Enter exact pixel dimensions, scale by percentage, or pick a ready-made social media preset for Instagram, Facebook, Twitter/X, LinkedIn, YouTube, and Pinterest.

Because everything runs locally on your device, your photos are never uploaded to a server. That means faster resizing, complete privacy, and no file-size or usage limits. Resize a single image or batch-process dozens at once, then download them individually or as a ZIP.

Frequently Asked Questions

Is this image resizer free?

Yes. It's completely free with no registration, watermarks, or limits on how many images you can resize.

Will resizing reduce the quality of my image?

Resizing to smaller dimensions keeps quality high. Enlarging beyond the original size can soften details, since new pixels have to be interpolated. Keep 'maintain aspect ratio' on to avoid distortion.

Are my images uploaded to a server?

No. All resizing happens locally in your browser using HTML5 canvas. Your images never leave your device, so the tool is fully private.

What image formats are supported?

You can resize JPG/JPEG, PNG, and WEBP images. Output is provided as a downloadable image you can use anywhere.

Can I resize several images at once?

Yes. Add multiple images, apply your settings, and download them individually or together as a ZIP archive.
