About this tool
Large photos slow down websites and fill up storage. Resizing a batch to a sensible width, such as 1280 or 1920 pixels, keeps pictures sharp while making them much lighter. Fit mode keeps the original proportions, so nothing gets stretched.
After resizing, you can squeeze each file further with the image KB reducer or change formats with the WEBP to JPG and PNG converter. Making a thumbnail for a clip? Grab one from the video to GIF maker.
Frequently asked questions
Will resizing stretch my pictures?
Not in Fit mode. It keeps the original ratio. Only Exact mode can stretch, and it says so in its name.
How many images can I resize at once?
There is no fixed limit. Very large batches depend on your device memory, so split huge batches into groups.
Which formats are supported?
JPG, PNG and WEBP in, and you can keep the same format or switch to JPG, PNG or WEBP.
Do my images leave my device?
No. All resizing happens in your browser.
