Need a picture at an exact size? Use this free image resizer in pixels to set your own width and height, fit or crop the photo to match, and download it as a JPG or PNG in seconds. Choose a quick preset like 1920 × 1080, or type in custom dimensions.
How to Resize an Image in Pixels
To resize an image in pixels, upload your photo, enter the width and height you need, choose how the image should fit, and download the result. Here’s the full process:
- Select your image. Click “Select Image” and choose a photo or graphic from your device.
- Set the size. Tap a preset (800 × 600, 1280 × 720, 1920 × 1080, or 1080 × 1080) or enter your own width and height in pixels.
- Lock the aspect ratio. Leave “Lock Aspect Ratio” on to keep the original proportions. Change one dimension and the other updates automatically, so nothing looks squished or stretched.
- Choose how it fits. Select a resize mode, a background, and a position. You can also drag the image inside the preview to reposition it.
- Pick a format and download. Choose JPG or PNG, then click “Download” to save your resized image.

Resize Modes Explained: Fit Inside, Fill & Crop, and Stretch
When your image and your target size have different proportions, the resize mode decides what happens to the extra space or the extra image.
Fit Inside
Scales the entire image to fit within your width and height without cropping or distortion. If the proportions don’t match, the leftover space is filled with the background you chose (white, black, transparent, or blurred). It’s the safest choice for product photos, logos, and screenshots, where you can’t afford to lose any part of the picture.
Fill & Crop
Scales the image until it covers the whole frame, then trims whatever extends past the edges. The Position setting (top, center, or bottom) controls which part of the image stays in view. Use it for profile pictures, thumbnails, and banners when you don’t want empty borders.
Stretch
Forces the image to the exact width and height you entered, even if that changes its proportions. People and objects can look wider or taller than they really are, so use Stretch only when matching an exact size matters more than appearance.

Pixels, Inches, and DPI: What’s the Difference?
Pixels measure the size of a digital image. A photo that is 3000 × 2000 pixels has 3,000 pixels across and 2,000 pixels down. Inches and centimeters only come into play when you print. To find the print size, divide the pixel dimensions by the DPI (dots per inch). For example, a 1200 × 1800 pixel image printed at 300 DPI comes out at 4 × 6 inches.
If you’re preparing an image for print, use our pixel to inch converter or the pixels to inches for printing tool. You can also check an existing file’s resolution with the image DPI checker.
Tips for Resizing Images Without Losing Quality
- Shrink instead of enlarge. Making an image smaller keeps it sharp. Enlarging forces the software to invent new pixels, which can make a photo look soft or blocky.
- Keep the aspect ratio locked. It prevents stretched faces and squashed logos.
- Choose the right format. JPG is best for photos and keeps file sizes small. PNG is best for logos, screenshots, and graphics with text, and it’s the format to pick if you need a transparent background.
- Resize to the size you’ll actually display. Uploading a 4000-pixel-wide photo to a spot that shows it at 800 pixels slows your page down. Resizing it first helps your pages load faster.
- Keep your original. Save the full-size file so you can export a different size later.
Frequently Asked Questions
How do I resize an image to a specific size in pixels?
Select your image, enter the exact width and height in pixels (or tap a preset), choose a resize mode, and click Download. Your image is saved at the exact dimensions you entered.
Is this image resizer free?
Yes. The PixelConverter image resizer is free to use. You don’t need to create an account, and it doesn’t add a watermark to your images.
Will resizing reduce my image quality?
Making an image smaller usually keeps it looking sharp. Enlarging an image beyond its original size can make it look soft or pixelated, because the extra pixels have to be estimated. For the best results, start with the highest-resolution original you have.
What’s the difference between Fit Inside, Fill & Crop, and Stretch?
Fit Inside shows the whole image and fills any leftover space with your chosen background. Fill & Crop covers the entire frame and trims the edges. Stretch forces the image into the exact size, even if that distorts its proportions.
Can I resize an image and keep a transparent background?
Yes. Choose the Transparent background and download your image as a PNG. JPG doesn’t support transparency, so a JPG always has a solid background.
What size should I resize my image to for social media or a website?
It depends on where the image will appear. As a starting point, use 1080 × 1080 pixels for square Instagram posts, 1280 × 720 pixels for YouTube thumbnails, and 1200 × 630 pixels for Facebook link previews. See the table above for more common sizes.
How do I make an image smaller in file size?
Reduce its pixel dimensions and save it as a JPG. Fewer pixels means a smaller file. To estimate how big a file will be at a given size, try the pixel to KB converter.
Are my images uploaded or stored?
No. Your image is processed in your browser and is never uploaded to our servers.
