Yes. Add up to 20 JPG, PNG, or WebP files. In pixel mode with proportions locked, the width and height are maximum bounds for each image. Download one result or the batch as a ZIP.

Reducing pixel dimensions often reduces file size, but not always. The tool shows the resulting size. For a strict upload limit, try Compress Image and review the actual file size.

Change Image Dimensions Without Changing the File Type

Resize JPG, PNG, or WebP images to a new width and height in pixels, or scale each photo by a percentage. Use a single image or a batch. By default, the tool keeps each image's proportions and avoids enlarging smaller images. Preview the actual dimensions before downloading, then save one image or all results as a ZIP.

Resizing changes pixel dimensions. It may change file size, but an exact file size is not guaranteed. If you need to make a photo smaller for an upload limit, use Compress Image after choosing suitable dimensions. Your image content is processed in your browser for this operation.

Choose the Image Size You Need

Resize by Pixels

Enter a new width and height. With proportions locked, the values act as a bounding box for mixed-size batches.

Resize by Percentage

Scale every selected image by the same percentage, such as 50% for half the original width and height.

Keep the Image Shape

Leave Keep proportions on to avoid stretching photos and document images.

Download or Make a PDF

Download one result, collect the batch in a ZIP, or carry the resized images directly to Image to PDF in this tab.

When Image Resizing Helps

  • Fit a document photo into a form's pixel dimensions
  • Scale a batch of phone photos before converting them to PDF
  • Make JPG or PNG images fit a website layout
  • Reduce the dimensions of a large image before sending it

Does Resizing Reduce Image File Size?

Often, but not always. Pixel dimensions and file size are different. PNG encoding remains lossless in this tool, while JPG and WebP are re-encoded. Check the shown output size; use Compress Image if you need more reduction.

What Happens to Transparency and Metadata?

PNG and WebP transparency is retained when the browser can export the same format. The new file is drawn from decoded pixels, so camera, location, color-profile, and other metadata may be removed. Keep the original if those details matter.

What if I Enlarge a Small Photo?

Upscaling creates more pixels but cannot restore detail missing from the original. The Do not enlarge option is on by default. Turn it off only when the requested dimensions are more important than sharpness.
