How to resize an image in pixels
- 1 Drop your images on the box, or click browse to choose them. You can add many at once.
- 2 Enter the width and/or height in pixels, or choose a preset.
- 3 Press Resize. One image downloads directly; several come in a ZIP file.
- 4 Check the new size and file size shown under each image.
Choosing the right pixel size
Match the size the image will be shown at. Profile pictures and thumbnails need a few hundred pixels; full-width website banners 1600 to 2000. For percentages and the full resizer, use Resize Image; to cut a shape first, use Crop Image.
- Fill and crop avoids stretched faces when the shape changes.
- Enlarging by more than 2× usually looks soft.
- Compress after resizing for the smallest files.

Frequently asked questions
What is a pixel?
The smallest dot in a digital image. A 1920 × 1080 image is 1,920 dots wide and 1,080 tall.
How do I keep the proportions?
Enter only the width or only the height. The other side is worked out automatically.
What does fill and crop do?
It fills the exact size you set and trims the edges that do not fit, like a cover photo, so nothing is stretched.
Can I make an image larger?
Yes, but enlarging cannot add detail, so a small photo made much bigger will look soft.
What size is an Instagram post?
1080 × 1080 for square, 1080 × 1350 for portrait and 1080 × 566 for landscape.
How do I resize by percentage instead?
Switch to the By percentage tab and enter, for example, 50%.
What about DPI?
DPI only matters for printing. On screens, the pixel size is what counts. At 300 DPI, 1,200 pixels prints at 4 inches.
Does resizing reduce the file size?
Making an image smaller in pixels usually reduces the file size a lot, because there are fewer pixels to store. Enlarging increases it.
What is the best size for website images?
Match the largest width the image is shown at, often 1200 to 1600 pixels for full-width images and 600 to 800 for content images.
Can I resize a photo on my phone?
Yes. Open this page in your mobile browser, choose photos from your gallery, enter the pixels you need and download the resized copies.
Are my images uploaded when I resize them?
No. Resizing happens in your browser, so the pictures stay on your device and the new copies download straight to it.
How this tool works. These image tools run entirely in your browser using the Canvas API built into every modern browser, the open-source libheif decoder for iPhone HEIC photos and Tesseract, a widely used open-source OCR engine, for reading text. Each tool is tested with real phone photos, screenshots and scans before it goes live, and nothing you open is sent to a server.
