The resizing is done entirely in your own browser tab. Your photo is never sent to a server, so it stays private and the result is ready the moment you click.

Resize an Image Without Losing Quality

Our online image resizer scales your photo to any size you need, by exact pixel dimensions or by a percentage, directly in your browser. It uses high quality smoothing so resized images stay crisp, and it keeps transparency intact when you export as PNG or WebP. Because nothing is uploaded, resizing is instant even for large files, and your images stay completely private.

It is ideal for preparing images for websites, email, marketplaces, social media avatars, forum signatures and print, or simply shrinking a large photo so it is easier to share.

How to Resize an Image (4 Steps)

  1. Upload your image. Drag and drop or click "Select image". It loads instantly and stays in your browser.
  2. Choose new dimensions. Enter the width and height in pixels, or switch to percentage to scale by a factor.
  3. Keep the proportions. Leave "Keep aspect ratio" on so the image is not stretched, or turn it off for an exact fit.
  4. Resize and download. Pick an output format and the resized image saves straight to your device.

Your Photos Are Never Uploaded

Plenty of resizers upload your photo to a server before they scale it. Here the pixels are resized right inside your browser, so your originals are never exposed and even large files stay on your own machine.

Pixels or Percentage

Set an exact width and height in pixels for a precise target size, or scale the whole image by a percentage when you just need it smaller. Aspect ratio is locked by default so nothing looks stretched.

Keeps Transparency

Resizing a transparent PNG keeps the transparent background intact when you export as PNG or WebP. Choose JPG only when you want a smaller file and do not need transparency.

Popular Sizes and Uses

People reach for this resizer to hit an exact social media size without cropping or guessing. Common targets include 1080 by 1920 for an Instagram or Facebook story, 1080 by 1080 for a square Instagram post, 1280 by 720 for a YouTube thumbnail, 851 by 315 for a Facebook cover, 1500 by 500 for an X or Twitter header, and 820 by 312 for a LinkedIn banner. Because you type any exact width and height, it also works for passport and ID photo sizes, eBay and Etsy listing images, forum avatars and signatures, and any fixed pixel size a web form or job application asks for.

Switch to percentage mode when you simply need a large photo to be smaller and faster to upload, for example scaling a phone photo down to 50 percent before emailing it or attaching it to a message. Everything still runs in your browser, so even resizing a high resolution camera photo to a tiny thumbnail happens instantly and stays private.

Frequently Asked Questions

Upload your image, enter the new width and height in pixels (or switch to percentage), keep aspect ratio on so it is not stretched, then click Resize and Download. The resized file saves straight to your device.

No. There is no upload step at all. Your picture is scaled inside your browser with the Canvas API and stays on your device from start to finish, so private images remain private.

Making an image smaller keeps it sharp because we use high quality smoothing. Enlarging an image beyond its original size will always look softer, since the extra pixels have to be invented; for best results, resize down rather than up.

Yes. Choose Pixels mode and type the exact width and height you need. Turn off Keep aspect ratio if you want it to fit those dimensions exactly without preserving proportions.

Yes. Switch the Resize by option to Percentage and enter a value, for example 50 to halve the size or 200 to double it.

Yes, as long as you export as PNG or WebP. Choosing JPG will remove transparency because the JPG format does not support it.

You can load JPG, PNG, WebP and GIF and other common formats. On download you can keep the original format or convert to PNG, JPG or WebP.

There is no artificial limit. Because everything runs in your browser, the only limit is your device memory, so very large images may use more RAM.

It is completely free with no account required and no watermark added to your image.

Choose Pixels mode and set the width to 1080 and the height to 1920, which is the full size of an Instagram or Facebook story. Turn off Keep aspect ratio if your source is a different shape and you want it to fill those exact dimensions.

A YouTube thumbnail is 1280 by 720 pixels, a 16 by 9 ratio. Enter those values in Pixels mode and download as JPG or PNG.

Use Pixels mode, type the exact width and height the form specifies, and turn off Keep aspect ratio so the result matches those dimensions precisely rather than preserving the original proportions.
