How to use Resize & Crop Image Online
- 1
Add an image
Choose, drag or paste the image you want to resize.
- 2
Resize changes dimensions, not the crop area
Set an exact width and height or scale by percentage. Keeping the aspect ratio locked avoids stretching; quick-width presets change width while preserving the selected proportions.
- 3
Crop removes pixels outside the selected area
Move and resize the crop box, use exact X/Y/Width/Height values, or choose a common aspect ratio. Cropping does not resize the selected pixels unless you switch back to Resize.
- 4
Export the resized image
Confirm the output dimensions, choose JPG, PNG, WebP or AVIF, then export the result.
About Resize WebP Image Online
Resize changes output dimensions by pixels or percentage. Lock the aspect ratio to avoid accidental distortion.
About WEBP
WebP is a web-focused image format that supports efficient compression and transparency, but some legacy workflows still expect JPG or PNG.
Frequently asked questions
Can a resized WebP keep transparency?
Yes. WebP output can preserve transparent pixels when the decoded source contains them. Choose PNG or WebP rather than JPG when transparency matters.
How do I resize a WebP without stretching it?
Keep Lock aspect ratio enabled so changing width, height, percentage, or a quick-width preset preserves the current proportions.
How does WebP quality affect the resized image?
WebP uses a quality setting. Lower values can reduce the new file size but may soften fine detail, text edges, or gradients; compare the exported result before using it.
Will resizing upload or replace my original WebP?
No. ViewerPix creates a new image locally in your browser. The original is not uploaded or replaced, and embedded metadata may not be carried to the resized file.
Private browser processing

WebP supports efficient lossy output and transparency. Quality affects WebP and JPG exports; PNG output is lossless.
