FAQ

Good to know.

How do I resize an image online for free?
To resize an image, open the Pixasur image resizer, drop in your JPG, PNG, WebP, or AVIF file, type a new width or height in pixels, and download the result. It is free with no signup, and the resize runs in your browser so the image never uploads to a server.
Is this image resizer free and private?
Yes, the Pixasur image resizer is free with no signup, subscription, or watermark, and it is private because every image is resized inside your browser. Nothing is uploaded, so your photos stay on your own device.
Does resizing an image lose quality?
Resizing an image down with the Pixasur resizer keeps it sharp because it re-samples with high-quality smoothing. Making an image larger than its original size cannot add real detail, so downscaling gives the best results.
Can I resize an image to an exact pixel size?
Yes, the Pixasur image resizer lets you type a width and height in pixels, such as 1920x1080, and it fits the image to those dimensions. Lock the aspect ratio to scale proportionally, or unlock it to fit inside a box you set.
Can I bulk resize many images at once?
Yes, the Pixasur image resizer processes hundreds of images in one batch and packages them into a single ZIP download. Because the work runs in your browser, there is no upload limit and no cap on how many files you can resize.
Can I resize images on my phone?
Yes, the Pixasur image resizer runs in any modern mobile browser on iPhone or Android with no app to install. Open the page, pick a photo from your gallery, set the new size, and save it back to your device.
