How to resize an image to 1024x768

1024 x 768 pixels is a classic 4:3 landscape image: 4 units wide for every 3 units tall. It is the classic 4:3 XGA size, so it still fits presentation slides, forum posts, small product listing images, and older screens without cropping, and it stays small enough to email or upload quickly while looking clear on a phone or laptop. The steps below resize any photo to exactly 1024 x 768 in your browser on ImageTool.us, with no upload and no signup.

1. Step 1: pick a photo and keep the original

Start with the photo you want to resize — any common format works (JPG, PNG, or WebP). Keep a clean copy of the original before you begin: the tool cuts a 4:3 rectangle from the center of your photo and resizes it to 1024 x 768, and the cut-off parts are not in the downloaded copy, so the only way to get the full photo back is to start over from the original. The original on your device is never changed; the tool only makes a new resized copy for you to download.

2. Step 2: open the tool and upload your photo

Open the Resize Image to 1024 x 768 tool and upload your photo — click to choose it, or drag and drop it onto the page. The original appears in the preview on the left. Nothing is uploaded: the file stays on your device and the work happens in your browser.

3. Step 3: click Resize to 1024 x 768

There are no settings to choose: the output is always exactly 1024 x 768 px as a JPG. Click Resize to 1024 x 768. The tool first cuts the largest 4:3 rectangle it can from the center of your photo — nothing is stretched — and then resizes that rectangle to 1024 x 768 px. The result appears next to your original so you can compare them before saving. If your photo is smaller than 1024 x 768 px, it is enlarged to 1024 x 768 px instead; enlarging does not add detail, so a very small original will still look soft — it just meets the size requirement.

4. Step 4: check the preview and save the result

Look at the edges before you download: on a square photo, the crop cuts from the top and bottom, and on a very wide photo, it cuts from the left and right. Make sure your subject is still fully in the frame and nothing important was cut off. When you are happy with it, tap Download below the result to save the new copy — it is called resized-1024x768.jpg.

What 1024x768 is

1024 x 768 is a landscape image with a 4:3 ratio: the width is one-third wider than the height. It was the standard size of older computer screens and projectors (XGA), which is why slides, forum software, and older websites still expect it. It works well as a slide image, a forum post image, or a small product listing image. At 1024 pixels wide it is sharp enough for phone and laptop screens, and a JPG at this size is usually well under 300 KB, so it uploads and emails fast. That is why it is a good larger 4:3 size: big enough to look clear on a slide or a small screen, small enough to share easily.

When 1024x768 is the right size

1024 x 768 suits small landscape displays first of all: a presentation slide, a forum post, or a small listing image. It is a good choice whenever the image will be shown small and landscape and you want it clear without a large file. It is a poor choice for a social media post or a product photo that will be shown large: a 1024 x 768 image shown at 1600 pixels wide will look soft, because the detail was never there. For a smaller 4:3 version, use Resize to 800x600; for a widescreen version, use Resize to 1280x720; for a square post, use Resize to 1200x1200. For the sizes each platform actually shows, see the Best Image Sizes for Social Media guide.

Keep the subject in the center

The tool crops from the center of the image, so the middle of your photo is what survives. Before you resize, check where your subject sits: if the person or object is in the middle, the crop will keep it. If the subject is off to one side — a person standing at the left edge of a wide photo, for example — the center crop may cut them off entirely. In that case, crop the photo in the Image Editor first, where you can choose which part to keep, and then run the result through the 1024 x 768 tool. The same rule applies to square photos: a square photo loses its top and bottom to reach 4:3, so check that nothing important sits at the top or bottom before you download.

Other resize sizes on ImageTool.us

1024 x 768 is one of several exact sizes on the site, and the right one depends on where the image will be shown. Resize to 800x600 makes the smaller 4:3 version, for the same uses at a smaller file size. Resize to 1280x720 makes the widescreen 16:9 version, for YouTube thumbnails and modern screens. Resize to 1920x1080 makes the full HD version, for large displays. Resize to 1200x630 makes the landscape size for link preview images. Resize to 800x800 makes the square version at a smaller width, for profile pictures. Resize to 1080x1080 makes the square size for social media posts. If you need the 4:3 shape rather than exact pixels, Crop to 4:3 cuts the same shape at your photo's original resolution. For any other size, the Image Resizer handles custom dimensions, and the Image Converter changes the file format afterward. For the sizes each platform actually shows, see the Best Image Sizes for Social Media guide.

Honest limits

• Center crop only. The tool always cuts from the center of the image; it does not let you choose which part to keep. If your subject is off-center, crop it in the Image Editor first.
• Square photos lose their top and bottom to the crop. A square photo must lose height to reach 4:3, and a panoramic photo loses even more from its left and right. A ratio that matches the photo suits those better.
• Resizing down cannot be undone from the downloaded file. The resized copy is a separate file, and the cut-off parts are not in it — check the preview before downloading and keep your original if you may want a different size later.
• A small photo is enlarged, not improved. If your photo is smaller than 1024 x 768 px, the tool enlarges it to 1024 x 768 px, but enlarging does not add detail — a very small original will still look soft.
• JPG output only. The result is always a JPG, which suits photos; it is not the right format if you need transparency — use PNG for that.

Common mistakes

• Resizing a square photo with the subject near the top or bottom — a center crop cuts the top and bottom first on square photos, so a person's head or feet can disappear. Check the preview, or crop in the Editor first.
• Forgetting to keep the original — if you want a different size later, you need the full photo. Keep it before you resize.
• Using 1024x768 for a large display — the image will look soft when shown bigger than 1024 pixels wide. A larger size keeps it sharp.
• Downloading without comparing with the original — the preview sits next to the original for a reason. Check that the subject is fully in the frame before you save.
• Expecting a small photo to become sharp — enlarging a small photo to 1024 x 768 px meets the size requirement, but it cannot add detail that was not there.

Quick checklist

• Original clean copy kept before resizing.
• Subject in the middle of the photo, so the center crop keeps it.
• Preview checked: subject fully in frame, nothing important cut off at the top, bottom, or sides.
• Downloaded as resized-1024x768.jpg.
• File too large to post? Run the result through the Compressor first.
• Need a different size afterward? Resize the original again, not the resized copy.
