Batch Image Resizer

Resize JPG, PNG and WebP images by size or percentage, one file or a whole batch. Everything runs on your device.

Your images are processed in your browser and are not uploaded.

Drag JPG, PNG or WebP images here, or

Still images only. Up to 20 images, 20.97 MB each, 83.89 MB in total, 25 megapixels per image. Output up to 10000 px per side.

Your images are processed in your browser and are not uploaded.

Resize settings

Fit keeps the whole image inside the box. No padding is added. Proportions are always kept.

Enlarging adds pixels but cannot recover detail that is not in the image.

Keeps each image's format, not its original bytes or metadata.

The background fills padding, and transparent pixels when it is white or black.

Resizing changes pixel dimensions, not guaranteed file size.

How to resize images

  1. Choose or drag in JPG, PNG or WebP images.
  2. Pick a mode: width, height, percentage, or an exact size with Fit, Crop or Pad.
  3. Press Resize, then download files or a ZIP.

Good to know

Proportions are always kept. Images are not enlarged unless you allow it, and enlarging cannot add detail. The preview before conversion is a layout preview; the real result appears after resizing.

Frequently asked questions

Are my images uploaded?

No. Your images are processed in your browser and are not uploaded. Nothing is saved after you close or reload the page.

What is the difference between Fit, Crop and Pad?

Fit keeps the whole image inside a box and may end up smaller than the box. Crop fills the exact size and trims the edges equally. Pad fits the whole image inside the exact size and fills the rest with a background colour. Nothing is ever stretched.

Does enlarging improve quality?

No. Enlarging adds pixels but cannot recover detail that is not in the image, so it is off by default.

What happens to transparency?

JPG cannot store transparency, so white or black is used instead. Choose PNG or WebP output to keep transparent areas.

Will a smaller size make the file smaller?

Usually, but not guaranteed. Resizing changes pixel dimensions. File size depends on the content and the format, and is shown as actually produced.

What happens to metadata?

Images are re-encoded by your browser. Orientation is applied to the pixels once, and location and camera metadata are not copied.

Which formats and limits apply?

JPG, PNG and still WebP, up to 20 images, 20.97 MB each, 83.89 MB combined and 25 megapixels per image. Output is limited to 10,000 px per side. GIF, animated images, SVG, HEIC, AVIF and PDF files are rejected with a message.
