How it works

  1. 1

    Add images

    Drop in the images you want to resize.

  2. 2

    Choose a size

    Set a target width in pixels or scale by percentage. Presets make it one click.

  3. 3

    Download

    Save one image or the whole batch as a zip. Files are never uploaded — everything happens locally.

Instant & 100% private — nothing is uploaded

Your images are processed instantly on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and no copies kept anywhere.

Frequently asked questions

Will resizing distort my images?
No. The aspect ratio is locked by default, so width and height stay proportional. You can unlock it to set an exact height.
Can I resize many images at once?
Yes. Add a whole batch and the same settings are applied to every image, then download them all as a zip.
Does it upscale images too?
It can, but enlarging beyond the original resolution will soften detail. For best quality, resize down rather than up.
What output format do I get?
Resized images keep their original format (JPG stays JPG, PNG stays PNG, and so on).
