How to use Resize WebP
- 1. Add the WebP to resize. Load the WebP file you want to scale, whether it is a photo that is larger than a page needs or an image that is too small for a design slot.
- 2. Set the target width and height. Enter exact pixel values in Width (px) and Height (px). Matching the source image's aspect ratio avoids stretching, while a mismatched ratio will squash or stretch the resample to fit.
- 3. Download the resampled image. Save the resized WebP at the new dimensions. Downscaling keeps detail sharp, while large upscales can look soft since the tool interpolates pixels rather than inventing new detail.
When to use Resize WebP
Resize WebP scales an image to exact pixel dimensions you specify. It is the tool for fitting a WebP to a fixed slot, whether that is a thumbnail grid, a hero banner, or an upload limit that caps dimensions.
- Fitting a hero image to a template. A CMS template expects a hero banner at exactly 1600 by 500 pixels, but your source photo is a different shape entirely. Resizing to that exact target gets it into the slot.
- Shrinking a photo before upload. A form caps uploaded images at 2000 pixels wide and your camera export is far larger. Downscaling first avoids the form rejecting the file for being too big.
- Generating a thumbnail grid. A gallery page needs every WebP resized down to the same 400 by 400 thumbnail size so the grid lines up evenly across dozens of images.
Examples
Downscale to 800×600
Input
photo.webp + 800×600
Output
photo.webp resampled to 800×600 pixels
About the Resize WebP tool
Resize WebP does its work locally, right in the browser. Scale a WebP image to an exact width and height in pixels. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the WebP Tools collection on EditSafely, a set of 57 small, focused WebP utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Width (px) and Height (px), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
