Resize images.
Set the exact pixels you need.
Resize JPG, JPEG, PNG and WebP images online for free. Set exact width and height, keep the original proportions when needed, and download the resized image directly in your browser.
Resize an image to exact dimensions
Use Pixmora when you need a specific width or height in pixels. Enter the required dimension and leave the other field blank when you want to preserve the original aspect ratio.
Common image resizing uses
- Website images: resize oversized photos to a sensible maximum display width.
- Forms and applications: follow the stated pixel dimensions and file-size requirements.
- Profile pictures: create a square copy when the destination requires equal width and height.
- Thumbnails: make a smaller copy rather than loading a full-resolution original.
Resize vs. compress
Resizing changes pixel dimensions. Compression changes how efficiently those pixels are encoded. For a much smaller file, resizing and then compressing can work better than compression alone.
Should you preserve the aspect ratio?
Usually, yes. Changing width and height independently can stretch or squash the image. If a destination requires a fixed rectangle, consider cropping before resizing so the subject keeps the intended proportions.
Which format should you choose?
JPG is a practical choice for many photographs, PNG is useful when lossless output or transparency matters, and WebP can provide efficient output for modern web workflows.
Need a smaller file after resizing?
Use the image compressor after resizing, or use target-size compression when a form gives you a KB limit.
