Will resizing a JPG image distort it?
No. The aspect ratio is locked by default, so proportions stay correct unless you choose to set both dimensions freely.

Resize JPG Images
Resize JPG images to exact pixel dimensions or a percentage of the original, entirely in your browser.
- Files stay on your device.
- Processed locally in your browser.
- No uploads. No storage.
Resize Image changes the dimensions of one image without uploading it to an image-processing service.
You can enter exact dimensions or scale by percentage, then review the output dimensions before processing.
What you can do
- Resize by width and height or by percentage.
- Lock the source aspect ratio while changing dimensions.
- Choose the output filename before downloading.
- Keep SVG files as scalable vectors and animated GIF files as animations.
Before you start
- Very large dimensions require enough browser memory for the decoded and output images.
- Upscaling creates more pixels but cannot recover detail absent from the source.
- Animated GIF processing requires a modern browser with module workers and OffscreenCanvas.
- WebP output depends on browser encoding support; an unavailable WebP encoder falls back to PNG with a clear notice.
How it works
- Choose the JPG image you want to resize.
- Set a width, height, or percentage; the aspect ratio stays locked by default.
- Download the resized JPG image.
Common questions
Can I resize by percentage?
Yes. You can scale an image to a percentage of its original size as well as to exact pixel dimensions.
Does the resized JPG image keep its format?
Yes. The resized image keeps its source format unless the browser cannot encode WebP, in which case VaultIMG clearly returns PNG instead.
