90

Applies to JPG and WebP. Lower means smaller files. 80–90 is good for photos

Add images, set the size, then click “Resize”.

How to use

  1. Choose or drop one or more images.
  2. Pick “Pixels” or “Percentage”. For pixels, enter a width or height; keep “Lock aspect ratio” on to preserve proportions.
  3. Choose an output format. JPG and WebP have a quality setting.
  4. Click “Resize”, then download each image or use “Download all (ZIP)”.

Tips

  • Common widths for social media, blogs and online shops: 1080, 1200 and 1920 px.
  • To just make files smaller, resize to 50% and save as JPG or WebP.

FAQ

Are my images uploaded?

No. Reading, resizing and saving all happen in your browser. Your images never leave your device.

With the aspect ratio locked, will images of different shapes get distorted?

No. When locked, only the side you edited last (width or height) is used, and the other side is calculated from each image's own ratio. Set the width to 1080 and both landscape and portrait photos become 1080 wide with different heights. Unlock it to force every image to exactly width × height, which may stretch them.

Will large reductions look jagged?

No. When shrinking by more than half, the image is halved step by step before the final resize, so fine lines and text stay smooth.

Can I enlarge images?

Yes, for example 200%. Enlarging doesn't add detail, so results look softer. Because of browser limits, output is capped at about 16.7 megapixels (4096 × 4096) or 16384 px on one side.

Which format and quality should I choose?

By default the original format is kept (GIF, BMP and other formats are saved as PNG). For photos, JPG or WebP at quality 80–90 works well. Choose PNG or WebP to keep transparency; JPG fills transparent areas with white.

What happens to orientation and EXIF data?

Phone photos are rotated upright using their EXIF orientation. The output is re-encoded and contains no EXIF, GPS location or other metadata.

Can I resize photos on my phone?

Yes. You pick the photos in your phone's browser and nothing is installed. Up to 50 images per run, each up to 200 MB. Resizing many large photos at once can exhaust a phone's memory, so work in smaller batches there.
