How to Increase the Resolution of an Image on Samsung

On a Samsung Galaxy, the quickest way to increase an image's resolution is Remaster picture in the Gallery app, if your phone supports it. If it doesn't, or the result isn't enough, you can enhance the photo online at 1K or 2K. Before either, make sure you are working with the original file, not a compressed copy.

First, check what you have

Open the photo in Gallery and swipe up to see its details, including the resolution in pixels. This tells you which problem you are solving:

• The photo is small (for example under about 1,000 pixels wide): it needs upscaling.
• The photo is large but looks soft: it needs sharpening or deblurring, not more pixels. Our guide to why photos are blurry helps you find the cause.
• The photo came from a chat or social app: look for the original first. Messaging apps often send a smaller copy.

Method 1: Remaster picture in Gallery

Samsung's Gallery app includes an AI tool called Remaster picture. According to Samsung's support page:

1. Open the Gallery app.
2. Select the photo you want to enhance.
3. Tap the three-dot menu.
4. Tap Remaster picture.
5. Compare the before and after versions. If you're happy with it, tap Save.

Availability: Samsung says Remaster is available on selected models and software versions only. If you don't see it in the menu, your phone or software version may not support it.

What it does: Samsung's camera team describes the newest version of Remaster as analyzing each photo for shake blur, low brightness, backlighting and noise, then applying up to three corrections in one pass. It also uses AI upscaling on low-resolution photos of 3 megapixels or less. Samsung lists this newest version as supported on the Galaxy S25 series, with later flagship models planned.

Tip: save a copy of the original before you remaster, so you can compare or go back if the result changes faces or text more than you'd like.

Method 2: Enhance the photo online

If your Galaxy doesn't have Remaster, the photo is larger than 3 megapixels, or you want more control, use an online enhancer. With Unblurfy:

1. Open Unblurfy's image upscaler in your phone's browser. Nothing to install.
2. Choose the photo from your Gallery. JPG, PNG, WebP and HEIC files up to 20 MB are supported.
3. Pick 1K or 2K and tap Enhance photo. 1K (about 1 megapixel) is free once a day, or twice when signed in. 2K (about 4 megapixels) uses credits.
4. Compare and download. Drag the slider or open the zoom view to check detail, then save the result back to your phone.

Photos and results are deleted after 24 hours, and there's no watermark.

Method 3: Start from a better original

Upscaling works best on the best copy you have. A few habits help:

• Get the original, not the chat copy. Photos sent through WhatsApp in Standard quality, or through regular text messages, are often reduced. Ask the sender to share the original with Quick Share, a cloud link, or WhatsApp's HD quality option.
• Avoid screenshots of photos. A screenshot saves only what's on screen, at your screen's resolution, and adds another round of compression.
• Shoot at full resolution next time. Many Galaxy models let you choose a higher-resolution photo mode in the camera. Options vary by model, so check your camera's settings.

Which method should you use?

What to expect

Increasing resolution adds pixels, and AI fills them with rebuilt detail. That makes small photos look clearer on modern screens and in small prints. It can't recover detail that was never captured, and it can redraw small text, faces and fine patterns. Compare the result with the original before you use it for anything important.
