Free image resizer online

Resize JPEG, PNG, and WebP images

Change the dimensions of JPEG, PNG, and WebP images while keeping the original format. Set width, height, or both. Aspect ratio lock prevents distortion.

  • Output keeps the original format
  • Files expire after 15 minutes
  • No account required

Supports JPEG, PNG, and WebP.

Choose images to resize

Upload images, enter the target width and/or height, and get resized versions in the same format.

Select, drop, or paste up to 20 images.

Resize options

Private by default

Uploaded files are processed and deleted within 15 minutes. No accounts, no cloud storage.

Format stays the same

A JPEG stays a JPEG, a PNG stays a PNG. Only the dimensions change.

Instant results

Most images resize in under a second. Batch up to 20 files at once.

Frequently asked questions

Can I set only the width and let the height adjust automatically?

Yes. Enter only the width, leave height empty, and enable 'Lock aspect ratio'. The height will be calculated automatically to match the original proportions.

Will the image be stretched if I set both width and height?

If 'Lock aspect ratio' is enabled, the image is scaled to fit within the dimensions you set without distortion. If it is disabled and you set both values, the image is scaled to exactly that size, which may stretch it.

Does resizing change the image format?

No. The output is the same format as the input: JPEG stays JPEG, PNG stays PNG, WebP stays WebP. To change format, use the main image converter.

Can I make an image larger than the original?

The resizer applies a 'scale down only' constraint by default: if the target size is larger than the original, the image is returned at its original size. This prevents unnecessary quality loss from upscaling.

Practical guides

Resize Images Without Stretching or Distortion

Stretching happens when width and height are forced into proportions that differ from the source. A reliable resize workflow preserves aspect ratio, supplies only the dimensions that matter, and avoids enlarging files that lack enough pixels.
