Image Resizer

Resize Images Online for Free

This free image resizer changes the width and height of your photo directly in your browser. Your file is never uploaded to a server, so your pictures stay on your device. It works with JPG, PNG and WebP images.

How to use the image resizer

Choose an image from your device. Its original size appears in the width and height boxes.
Type the new width or height in pixels. Keep Keep aspect ratio ticked so the other value updates automatically.
Choose an output format. Same as original keeps your current file type.
For JPG and WebP, set the quality. A value between 80 and 90 gives a good balance of sharpness and file size.
Click Convert, check the preview and download your resized image.

How to Resize an Image Without Making It Blurry

The best way to keep a resized image sharp is to make it smaller, not larger. Shrinking a photo discards pixels you no longer need, so the result usually still looks crisp. Enlarging it forces the software to guess new pixels, and that is what causes softness.

To keep quality high, start from the original file rather than a copy that was already resized or compressed. Keep the quality slider at 85 or higher for JPG and WebP, and save the result as PNG if the image contains text, logos or sharp lines. If you need a larger image, use an upscaler and expect a limit to how much detail can be restored.

How to Change the Pixel Dimensions of a Photo Online

Pixel dimensions are the width and height of an image, written as width × height, for example 1920 × 1080. To change them with this tool, upload your photo and enter the new values in the Width and Height fields. The tool shows the original size first so you can see exactly what you are changing.

Common targets are 1920 pixels wide for full-screen web images, 1080 pixels wide for social media posts, and 800 pixels wide for blog content. After you click Convert, the result shows the old and new size along with the old and new file size, so you can confirm the change before downloading.

How to Resize an Image for an Email Attachment Without Losing Quality

Many email services limit the total size of attachments, often to around 20 to 25 MB, and large photos from a phone or camera can reach that limit quickly. The easiest fix is to reduce the pixel dimensions. A photo that is 4000 pixels wide is far larger than any screen needs, and bringing it down to around 1600 to 2000 pixels makes the file much smaller while still looking sharp on screen.

For extra savings, set the output to JPG or WebP and leave quality at 80 to 90. Avoid going much
