How to resize image
- Add the image. Drop one or more images onto the tool or browse for them.
- Set dimensions. Enter a width and height (or a scale) and choose whether to keep the aspect ratio.
- Pick a format. Choose JPG, PNG, or WebP for the output depending on where it will be used.
- Download. Save the resized, converted image to your device.
Resizing is the everyday fix for images that are too big for an avatar slot, an email, or a web page — or in the wrong format for a system that only accepts PNG or WebP. Doing it in the browser keeps private photos off any server.
Set exact dimensions or scale by a percentage, keep or release the aspect ratio, and pick the output format for the destination. Downscaling is lossless in perceived quality; enlarging by resizing alone will soften fine detail.
To reduce a photo's file size without changing its dimensions, use Compress. To make an image genuinely larger with detail reconstruction, use the Image upscaler, and to strip location and camera data before sharing, use Remove EXIF.
Frequently asked questions
Will resizing keep the aspect ratio?
Yes if you leave the lock on — set one dimension and the other follows. Unlock it to stretch to exact dimensions.
Which format should I choose?
JPG for photos where size matters, PNG for graphics with transparency or sharp edges, and WebP for the smallest files with good quality.
Can I upscale an image here?
You can enlarge dimensions, but simple resizing softens detail. For AI-based enlargement use the Image upscaler in Vision Studio.
Are my images uploaded?
No. Resizing and format conversion happen in your browser tab; the pixels never leave your device.
