How it works

  1. Drop in your imagesAny number, any mix of JPG, PNG, WebP or HEIC.
  2. Choose the sizeLongest side (like 1920 or 1080 pixels), a percentage, or an exact width × height — cropped to fill, fitted inside, or stretched.
  3. DownloadEach image on its own, or all of them in a ZIP. Change the format too if you like.

Common sizes

Web pages1600–1920 px on the longest side is sharp on most screens and loads fast.
Instagram1080 px wide — 1080 × 1080 square or 1080 × 1350 portrait.
Email800–1200 px keeps attachments small and still looks good.
PrintFor a 6 × 4 inch print at 300 dpi you need 1800 × 1200 px — resizing up won’t add detail.

FAQ

Are my images uploaded?

No. Every image is processed inside your browser on your own device. Nothing is sent anywhere — and location and camera data are stripped from the files you download.

Does resizing keep the aspect ratio?

Yes for “longest side” and “percentage”. For an exact size, choose Crop to fill or Fit inside to keep the proportions, or Stretch to force the exact shape.

Can I make an image bigger?

Yes, but enlarging can’t add detail, so it will look softer. Longest side only ever shrinks images; use an exact size to enlarge.

Will resizing reduce the file size?

Almost always — halving the width and height cuts the pixels to a quarter.

Can I resize many photos to the same size?

Yes — drop them all in; every image gets the same settings.

Is it free?

Yes — free, no sign-up, no watermark and no limit on the number of images. The site is supported by the ads on the page.
