Resize modes explained
- Fit inside a box keeps proportions and makes each image no larger than the width and height you set. Great for websites and online shops.
- Exact size makes every image the same dimensions, cropping from the center, adding a border, or stretching.
- Set width or Set height fixes one side and calculates the other.
- Percentage scales every image by the same amount.
Formats and file names
Keep each file's original format or convert all of them to JPG, PNG or WebP. A suffix such as -resized is added to the name, or leave it empty to keep the original names. If two files end up with the same name, the ZIP numbers them so nothing is overwritten.
Limits
Images are processed one at a time in your browser, so even big batches do not need a fast connection. Very large photos and huge batches use more memory; on a phone, batches of 20 to 50 photos work best. HEIC photos are supported and converted automatically.
Frequently asked questions
How many images can I resize at once?
Up to 200 per batch. Larger batches work best on a computer with plenty of memory.
Will small images be blown up?
Not by default. The Don't enlarge option keeps images that are already smaller than the target at their original size.
Can I resize everything to 1080 x 1080 for Instagram?
Yes. Choose Exact size, pick the Instagram square preset, and choose Crop to fill so nothing is stretched.
Are my photos uploaded?
No. All resizing happens on your device in the browser.
Can I convert to WebP while resizing?
Yes. Choose WebP as the format and set the quality.
