Leave one side empty to keep the shape. With both sides set, choose how the image fits.

With a size limit, the quality is lowered first and the image is made smaller only if needed. The background fills padding and transparent areas in JPG.

Your images are resized in your browser and never uploaded.

About this image resizer

Resize up to 15 images at once to an exact width and height, by percent, or to a ready-made size for Instagram, YouTube, Facebook, X, LinkedIn or a passport photo. Choose whether the image fits inside, fills the size and crops the edges, or gets coloured borders, and set a maximum file size for forms that only accept small uploads. Everything happens in your browser.

How to use it

  1. Add images: JPG, PNG, WebP, HEIC and more.
  2. Choose width and height, a percent, or a social media size.
  3. Optionally pick the format, quality and a maximum file size in KB.
  4. Choose Resize, then download each image or all of them as a ZIP.

Frequently asked questions

Are my images uploaded?

No. They are resized by your own browser and never leave your device.

How do I keep the shape of my image?

Fill in only the width or only the height, and the other side follows. With both filled in, choose Fit inside to keep the shape within that size.

How does the maximum file size work?

The resizer first lowers the quality step by step and keeps the highest quality that fits. If even low quality is too big, it makes the image smaller until it fits. PNG has no quality setting, so only its size can change; choose JPG or WebP for the smallest files.

Can it make images bigger?

Yes, with a width and height or a percent above 100. Enlarging cannot add detail, so very large enlargements look soft.
