About this tool

Resize Image Online

This free image resizer changes the width and height of a JPG, PNG or WebP picture to the exact pixel size you need. Type a new width or height, resize by percentage, or pick a preset for Instagram, YouTube, Facebook or X. Keep the aspect ratio locked so nothing looks stretched, and see a live preview with the new dimensions and file size before you download.

It is handy whenever a website or form asks for specific dimensions: a profile picture, a banner for social media, product photos for an online store, or a photo for a job or exam application that must be, say, 600 × 800 pixels. Shrinking large camera photos also makes them quicker to email and share.

You can also use it to convert an image format — resize a photo and save it as WebP, JPG or PNG, with a quality slider to reduce the file size further. Everything runs locally in your browser, so your photos are never uploaded to a server.

  • Exact pixel dimensions

    Set any width and height in pixels to match the size a website, form or social platform asks for.

  • Aspect ratio lock

    Change one side and the other updates automatically, so photos never look squashed or stretched.

  • WebP, JPG or PNG output

    Save the resized image in the format you need, which also works as a quick JPG to PNG converter.

  • Quality slider

    Lower the quality to make the resized file smaller, and check the new size before downloading.

Upload the image, turn off the aspect ratio lock and type 600 for both width and height. Choose Crop to fill so the picture isn't squashed, then download. The same works for any size, such as 1080 × 1080 for Instagram or 200 × 230 for bank exam forms.

Making an image smaller keeps it sharp. Making it much larger than the original can look blurry, because no new detail can be added.

Keep the aspect ratio option turned on. When you change the width, the height updates automatically (and the other way round).

WebP, JPG and PNG. WebP usually gives the smallest file, JPG works everywhere, and PNG keeps transparency.

Yes. Upload your image, keep the original width and height, and choose PNG, JPG or WebP as the output format. Transparent areas become white when saving as JPG.

Resizing changes the width and height in pixels. Compressing keeps the same dimensions and makes the file smaller. To only reduce the file size, use the Image Compressor.

Check the pixel size the form asks for, type that width and height, and download. If the shape differs from your photo, crop it first with the Image Editor so it isn't stretched.

No. Your images are processed entirely in your browser and never leave your device, so nobody else can see them.
