Get the exact dimensions you need
Every platform wants a different size: a 1080 × 1080 Instagram post, a 1280 × 720 YouTube thumbnail, a 2 × 2 inch US passport photo. This resizer gets you there in a few clicks without distorting the picture.
Type the pixels yourself with the aspect ratio locked, scale everything by a percentage, or choose a preset. For presets you decide how the photo fits the new shape: crop to fill, fit inside with a border, or stretch. Large reductions are done in several smooth steps, so small versions stay sharp instead of jagged.
How to resize an image
- 1
Open your image
Choose a JPG, PNG, WebP or other image, drag it in, or paste it with Ctrl + V.

Pixels for exact values, Percentage to scale evenly, or Social & print sizes for presets.

Resize and download
The new image keeps the original format and is ready to save.

Common uses
- Application forms: Produce the exact pixel size a portal demands, then compress it to the KB limit.
- Social media: Post images at the size each network displays, so they aren't cropped or blurred.
- Websites and blogs: Serve images no larger than they appear on screen for faster pages.

Tips and good to know
- Making an image larger than its original can't add detail — it will look softer. Resize down whenever possible.
- Forms often have a file-size limit too. After resizing, use the Image Compressor with a KB target.
- Need to choose exactly which part stays in the frame? Crop first with the Image Cropper.
- Centimetres to pixels: multiply by 118 for a 300 DPI print (so 3.5 cm ≈ 413 px).
