Use Adobe Express to Resize Images Online

Before you start

Adobe Express offers an online image resizer that runs through your browser. You need an Adobe account to use it, and the tool requires an internet connection because the resizing work is handled by the Adobe Express service, not locally on your device. Have the image file ready on the computer or mobile device you plan to use.

For best results, start with the highest quality version of the image you have. If the image will be used at a specific pixel size on a website or in an app, decide that size before you begin. If you are resizing a logo or graphic that must keep its background invisible, use a file format that supports transparency, such as PNG or SVG, and avoid converting it to a format that does not.

Step-by-step instructions

Step-by-step instructions for resizing an image in Adobe Express:

• Open the Adobe Express image resizer in a web browser and sign in to your Adobe account.
• Upload the image you want to resize. You can usually drag the file into the browser window or use the upload button to select it from your device.
• Enter new pixel dimensions in the width and height fields. If the image needs to keep its proportions, keep the aspect ratio lock enabled so changing one side updates the other side automatically.
• If you need a specific shape for a platform such as a social media post or presentation slide, choose the matching preset instead of entering dimensions manually.
• Check whether the tool offers options such as cropping, rotating, or fitting the image to a canvas. These may appear differently depending on the version or template you are using.
• Select a file format when the download option is available. PNG preserves transparency and is often better for graphics with sharp edges; JPEG is usually smaller for photographs but does not preserve transparency.
• Download the resized image to your device.

Check the output

Open the downloaded file and inspect it at the size where it will actually be used. Confirm that the pixel dimensions are correct, the main subject is not visibly distorted, and important parts are not cut off. If the image has text or a logo, zoom in to make sure it is still readable after resizing.

If you chose a preset, verify that the file shape works for the intended platform before publishing it. For transparent graphics, place the file over a contrasting background or upload it where the background should be invisible to confirm that transparency was preserved.

Common problems and next steps

If the image becomes blurry, you may be scaling it beyond its original size or downloading it with strong compression. Start again with a larger source file when one is available, or reduce the target pixel dimensions. If the result looks stretched, unlock any automatic resizing and check whether the aspect ratio is being locked before you enter new values.

When the downloaded file is larger than expected, try a different format or adjust the quality setting if the interface provides one. PNG is not ideal for detailed photographs when a small file size matters. If transparency disappears, confirm that you exported PNG or SVG rather than JPEG, because JPEG fills transparent areas with a background color.

If you need a precise pixel size and the online resizer rounds or blocks your input, download the closest available size and check whether your publishing tool can also resize the final output. Keep a copy of the original image before applying more changes.
