How to use Image Resizer
Resize photos by exact pixels, percent, long or short edge, a maximum box, or presets for Instagram, YouTube, X and other platforms. Each image in a batch keeps its proportions, and the high-quality Lanczos3 resampler runs right in your browser.
- 1
Drop your images on the page or paste them with Ctrl+V.
- 2
Under Resize by, choose Pixels, Percent, Edge, Fit in box or Presets.
- 3
Enter the size. With the chain lock on, type only the width or height; unlock it for an exact size and pick Crop to fill, Add border or Stretch under When the shape differs.
- 4
Under Resampling, keep Sharp for photos or choose Smooth or Pixel art, and turn on Never enlarge if small images should keep their size.
- 5
Check the size shown under the preview, then click Apply and download, or Apply to N images for a batch.
Frequently asked questions
Are my images uploaded?
No. Resizing runs in your browser, so your images never leave your device.
How do I give portrait and landscape photos the same size?
Choose Edge and set the Long edge, for example 1920 px, so every photo gets the same longest side. Fit in box instead keeps each photo inside a maximum width and height. Neither mode crops anything.
How do I get an exact size like 1080 × 1080 without distortion?
Pick a preset, or unlock the aspect ratio under Pixels, then choose Crop to fill to trim the overflow from the center, or Add border to fit the whole image on a colored or transparent border. A transparent border needs PNG or WebP output.
Can I enlarge a small image?
Yes, but enlarging can't add detail, so the tool shows a warning with the factor and the result looks softer. Each side can be at most 16,384 px, the largest size browsers can draw.
Which resampling option should I use?
Sharp (Lanczos3 with gamma correction) gives the crispest photos. Smooth (Mitchell) avoids ringing around hard edges. Pixel art (nearest neighbor) keeps hard pixel edges for pixel art, icons and QR codes.
Are DPI and EXIF data kept?
No. Saved files don't carry over the original DPI tag or EXIF data such as camera and location. DPI only matters for printing; the tool shows the print size at 300 DPI for reference.
