How to resize images

  4. 4Click Resize, then download each image or all of them as a ZIP file.

Why resize images?

Modern phones take photos of 4000 pixels wide or more, far bigger than a screen needs. Resizing them to 1200–2000 pixels makes files much smaller and faster to upload, email and load on websites.

Many websites, marketplaces and forms also require images of a specific size, such as a 1080 × 1080 pixel square for social media or a maximum width for a profile picture.

With "Keep aspect ratio" on, you can enter just a width or just a height and the other side is calculated for you. If you enter both, the image is fitted inside that box without being stretched.

Frequently asked questions

Will resizing reduce the quality?

Making images smaller keeps them sharp, because we use high-quality scaling. Making images larger than the original can't add detail, so enlarged images may look soft.

What does "Keep aspect ratio" do?

It keeps the image's proportions, so it isn't stretched or squashed. Turn it off only if you need an exact width and height and don't mind distortion.

Can I resize many images to the same size?

Yes. Add all your images, choose the size once, and every image is resized with the same settings.

Which format are resized images saved in?

By default, the same format as the original. You can also choose JPG, PNG or WebP. JPG and WebP are saved at high quality (92%).

Is photo information (EXIF) kept?

No. Metadata such as the camera model and GPS location is removed, and photos are rotated the right way up.

Are my files uploaded to a server?

No. The conversion happens entirely in your web browser, on your own device. Your files are never sent to us or anyone else, so they stay completely private.

Is it really free?

Yes. There is no sign-up, no watermark and no limit on how many files you convert. The only limit is your device: very large files need more memory.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux. Very large files may take longer on older phones.
