What is SizeShift?

SizeShift is a free online image resizer. Set an exact width in pixels, or scale a picture by a percentage, and download the new size in seconds. It works with JPG, PNG and WEBP files and never adds a watermark.

Keep the aspect ratio locked and the height follows the width, so nothing gets stretched. Untick it to set the width and height separately, for example to fit an exact banner size. Resize up to 5 images at once, and keep their format or save them as JPG, PNG or WEBP.

Each file shows its new size in pixels and kilobytes, and you can download them one by one or as a ZIP. Resizing happens in your web browser, so your pictures are never uploaded. Try it without an account; saving the resized images needs a free ToolClik account.

What you can do

  • Exact pixels

    Type any width from 1 to 12,000 px. With the aspect ratio locked, the height is worked out for you.

  • Resize by percentage

    Scale pictures from 5% to 200% of their size with one slider.

  • Free width and height

    Untick “Keep aspect ratio” to set both sides yourself, for banners, covers and forms that ask for an exact size.

  • Change the format as you go

    Keep each file's own format, or save every resized picture as JPG, PNG or WEBP.

  • Batch resize

    Resize several images in one go. Each shows its new size in pixels and kilobytes, and you can download them all as a ZIP.

Questions about Image Resizer

Is this image resizer free?

Yes. Resize up to 5 images at a time, up to 50 MB each, with no watermark. Downloading needs a free ToolClik account. Pro, at $1.29 a month, removes the batch limit and takes files up to 2 GB.

How do I resize an image to 1080 pixels wide?

Choose Pixels, type 1080 in the width box and keep “Keep aspect ratio” ticked. The height is worked out for you, so the picture keeps its shape.

Does resizing reduce quality?

Making a picture smaller keeps it sharp. Making it bigger adds pixels but not detail, so it can look soft; for that, try the free Image Enhancer.

Can I resize many images at once?

Yes. Free resizes up to 5 images at a time with the same settings, and Pro has no limit. Download them one by one or together as a ZIP.

Are my pictures uploaded?

No. SizeShift resizes your images in your browser on your own device. They are never sent to ToolClik.

Does it work on my phone?

Yes. Open the page in your phone's browser, pick photos from your gallery, set the size and download.
