JPEG · PNG · WebP 25 MB / 20 imagesBatch resize images by pixels or percentage
Set the dimensions of JPEG, PNG and WebP photos without uploading them. Resize one image or a batch of up to 20. The aspect ratio is locked by default to keep the picture from stretching.
How to use this tool
- Open your images and choose Pixels or Percentage.
- Enter the desired width, height or percentage. Keep the aspect ratio locked for proportional resizing.
- Generate the files. Check the actual dimensions and download the selected images or their ZIP.
Settings and output
- With the ratio locked, a pixel width applies that width to each image and calculates its height from its own proportions.
- Percentage mode scales every image relative to its original dimensions, which works well for mixed portrait and landscape batches.
- Unlock the ratio only when stretching is intentional. Use the crop tool first when you need a different shape without distortion.
Common questions
Can I make an image 1200 pixels wide?
Choose Pixels, keep the aspect ratio locked and set Width to 1200. Each image receives a proportional height. The resulting width may be lower if you accept a suggested safe output size.
Will enlarging a photo restore missing detail?
No. Resizing interpolates existing pixels. It can produce a larger file, but it does not reconstruct detail that was absent in the source.
