A straightforward online image resizer

Resize.Tools changes the pixel dimensions of JPG, PNG, and WebP images without requiring an account. Keep the aspect ratio locked for proportional resizing, or unlock it when you specifically need an exact width and height.

When to change image dimensions

Smaller dimensions can make images easier to share, faster to load on a website, and better suited to a fixed layout. Larger dimensions can fit a required canvas, but enlarging cannot recreate detail that was not present in the original.

How to use this tool

Choose or drop a supported image into the tool.
Set dimensions, optionally crop and position the image, then choose format and quality.
Process, preview the result, and download the new file.

Frequently asked questions

Are my images uploaded anywhere?

No. Resize.Tools processes supported images locally in your browser. The image does not need to be sent to a Resize.Tools server.

Does resizing reduce image quality?

Reducing dimensions normally preserves a clean appearance, while enlarging an image can reveal softness or pixelation. JPG and WebP quality settings can also affect detail and file size.

How do I resize without stretching the image?

Keep Lock aspect ratio selected for a normal resize. For an exact frame with different proportions, choose Fit inside to keep the entire image visible or Crop to fill to cover the frame.

How does crop positioning work?

Crop to fill keeps the output proportions and removes excess image area. Use a quick position or the horizontal and vertical sliders to decide which part stays visible.

Which image formats are supported?

The first version supports JPG, PNG, and WebP input and output in modern browsers.

Is Resize.Tools free?

Yes. The image resizer is free to use, requires no account, and does not add a watermark.
