Image Resizer
Change the size of JPG, PNG, WebP, and HEIC images. Set an exact width and height in pixels, scale by a percentage, enter a print size in centimeters or inches, or pick a size for Instagram or YouTube. Resize one image or a whole batch, right in your browser.
Drag and drop images here, or
JPG, PNG, WebP, and HEIC, up to 50 MB each. Add one or many. Nothing is uploaded.
Shape locked: type a width or a height and the other side follows each image, so nothing is stretched or cropped.
What the image resizer does
An image is a grid of pixels, and its size is how many pixels wide and tall that grid is. Resizing redraws the image onto a grid of a new size. Making it smaller blends neighboring pixels together, and making it bigger fills in the new pixels from the ones around them.
This resizer gives you four ways to set the new size: exact pixels, a percentage, a print size in centimeters or inches, or a ready-made social media size. When the new size has a different shape from your image, you choose whether to crop, add a background, or stretch.
When shrinking a lot, the image is reduced in halving steps instead of one big jump, which keeps thin lines and text smooth instead of jagged.

How to resize an image to an exact size, like 600 × 600
In the Pixels tab, the link icon between width and height controls the shape. With it locked, you type one side and the other follows your image, so a 3000 × 2000 photo set to 800 wide becomes 800 × 533. Nothing is cropped or stretched.
To get an exact size such as 600 × 600, click the link icon to unlock it and type both numbers. Your image probably has a different shape, so choose what happens to the difference:
- ·Crop to fill. The image fills the whole size and the extra is trimmed evenly from both edges. Best for profile pictures and social posts.
- ·Fit inside. The whole image is kept, and the empty space around it is filled with white, black, a color, a gradient, or transparency (PNG and WebP only).
- ·Stretch. The image is squeezed to the exact size. People and circles will look distorted, so use this only when the shapes are already close.
How to resize an image in cm or inches for printing
A printed size depends on two things: the pixels in the image and the DPI (dots per inch) it is printed at. In the Print size tab, enter the size you want and pick a DPI, and the tool works out the pixels. It also saves the DPI inside JPG and PNG files, so apps like Word and macOS Preview place and print it at that size. These are the pixel sizes at 300 DPI:
| Print size | Common use | Pixels at 300 DPI |
|---|---|---|
| 2 × 2 in | US passport and visa photo | 600 × 600 |
| 3.5 × 4.5 cm | Passport photo in the UK, EU, and many other countries | 413 × 531 |
| 4 × 6 in | Standard photo print | 1200 × 1800 |
| 5 × 7 in | Larger photo print or card | 1500 × 2100 |
| 8 × 10 in | Framed print | 2400 × 3000 |
| A4 (21 × 29.7 cm) | Full page document or poster | 2480 × 3508 |
Official passport and visa photos also have rules about head size and background. For those, the passport photo maker lines up the face for you.
Image sizes for social media
These sizes are built into the Social media sizes tab. Uploading at the exact size means the site does not crop your image in its own way.
| Where | Size in pixels |
|---|---|
| Instagram post, square | 1080 × 1080 |
| Instagram post, portrait (4:5) | 1080 × 1350 |
| Story or Reel (9:16) | 1080 × 1920 |
| YouTube thumbnail | 1280 × 720 |
| X (Twitter) header | 1500 × 500 |
| LinkedIn profile background | 1584 × 396 |
Image resizer options
- ·Pixels. Type a width, a height, or both, up to 16,384 pixels on a side. The link icon keeps or frees the shape.
- ·Percent. Scale from 5% to 300%. Each image in a batch keeps its own shape.
- ·Print size. Width and height in inches, centimeters, or millimeters, at 72 to 600 DPI.
- ·Save as. Keep each image's own format, or save as JPG, PNG, or WebP. HEIC, GIF, BMP, and AVIF images are saved as JPG when you keep the format. WebP files do not store DPI.
- ·Quality. 50% to 100% for JPG and WebP, 90% by default. To hit a file size limit in KB, use the image compressor after resizing.
Why an enlarged image looks blurry
Making an image smaller throws away pixels you do not need, so it stays sharp. Making it bigger has to invent new pixels by blending the ones around them, which softens edges and cannot add detail that was not in the photo. A small upscale often still looks fine, but for big jumps, start from a larger original if you can. For pixel art, use the pixel art scaler, which enlarges without any blur.
When to resize an image
- ·Posting on social media. Instagram, YouTube, X, and LinkedIn each have their own image sizes. Resizing to the exact size stops the site from cropping your picture in a way you did not choose.
- ·Filling in online forms. Visa, exam, and job applications often ask for a photo of an exact pixel size, like 600 × 600.
- ·Printing photos. Set a print size such as 4 × 6 inches or 3.5 × 4.5 cm and the image is made with the right number of pixels and DPI for a sharp print.
- ·Building websites and emails. A 4000 pixel phone photo is far bigger than any web page needs. Resizing it down makes pages and emails load much faster.
Frequently asked questions
- How do I resize an image to a specific size like 600 × 600?
- Choose Pixels, click the link icon to unlock the shape, and type 600 for both width and height. If your image is not square, pick Crop to fill to trim the edges, or Fit inside to keep the whole image and add a background around it. Then download.
- How do I resize an image without stretching it?
- Leave the shape locked (the link icon) and type only the width or only the height. The other side is worked out from each image, so nothing is squashed. When you need an exact size with a different shape, use Crop to fill or Fit inside instead of Stretch.
- How do I resize an image in cm or inches?
- Open the Print size tab, enter the width and height, choose centimeters, millimeters, or inches, and pick a DPI (300 is right for photo prints). The tool shows the pixel size it will make and saves the DPI in JPG and PNG files so the image prints at that size.
- What DPI should I use?
- Use 300 DPI for photo prints and anything viewed up close. 150 DPI is fine for large posters seen from a distance. DPI does not matter for screens, websites, or social media, which only look at the pixel size.
- Does resizing an image reduce its file size?
- Making an image smaller in pixels usually reduces the file size a lot, since there is less to store. If you need the file under a set size like 100 KB, use the image compressor, which can also lower the quality.
- Why does my image look blurry after making it bigger?
- Enlarging spreads the same pixels over a larger area, and the tool has to fill the gaps by blending neighbors. It cannot add detail that was not in the photo. The file list marks enlarged images so you can tell.
- Can I resize many images at once?
- Yes. Add as many images as you like and they are all resized with the same settings. With the shape locked, each image keeps its own proportions. Download them together as a ZIP file.
- Can I resize iPhone HEIC photos?
- Yes. HEIC photos are opened in your browser and saved as JPG by default, or as PNG or WebP if you choose.
- Does resizing keep the photo's metadata?
- No. The resized file holds only the picture, without EXIF data such as the camera, date taken, or GPS location. Print size mode adds the DPI you chose and nothing else.
- Are my images uploaded?
- No. Everything happens in your browser on your own device, so your images are never sent to a server or stored anywhere.
