Aspect ratio is kept
Resize image
Pixel dimensions matter more than file weight when an image goes into a layout, an email or a product card. Set the width you need: the height is calculated automatically and the proportions stay intact.
The image is processed in your browser and never uploaded.
How to resize
- 1Upload a photo or drop it into the window
- 2Pick a preset percentage or type a width in pixels

What to know
Downscaling keeps the image sharp and noticeably reduces file size. Upscaling does not add detail: the image is stretched, so a large result from a small source looks soft.
The aspect ratio is locked: changing the width recalculates the height automatically, so photos are not distorted and objects are not stretched.
The result keeps the source format for JPG, PNG and WebP. Other formats, including HEIC from iPhone, are saved as JPG.
Frequently asked questions
Is the photo uploaded to a server?
No, resizing runs in your browser and the file stays on your device.
Can I make an image larger?
Yes, but quality will not improve: detail that is not in the source will not appear. Look for a larger original instead.
Is the aspect ratio preserved?
Yes. You set one side and the other is calculated from the original proportions.
What size should I use for a website?
A product card usually needs 800–1200 px on the long side and a thumbnail 300–400 px. This reduces page weight and speeds up loading.
