Image Resizer
Set exact pixel dimensions or scale by a percentage, in bulk.
Free image and photo resizer: set exact pixels or a percentage, for one image or hundreds. Keep the proportions or fill a frame. Nothing is uploaded.
What Image Resizer is for
For when the dimensions matter rather than the file size: a profile picture that must be square, a header that must be exactly 1600 pixels wide, or a folder of photos that all need to be the same size before they go anywhere.
Pixels or percentage
Set a width and the height follows in proportion, or set both and choose whether to fit inside, fill and crop, or stretch. A percentage suits a batch of images of different sizes.
Common sizes
Web images: 1200 to 1920 pixels wide. Email: 800 to 1200. Instagram: 1080 wide. Passport and exam forms usually state their own, often a few hundred pixels.
Never enlarge
Enlarging an image adds pixels but not detail. The "never enlarge" option leaves small images at their size when a batch contains a mix.
How to use it
- Add your files. Drop them on the page or choose them. They stay on your device.
- Set the output format and quality. The defaults suit most files.
- Press convert and save the results, individually or as one ZIP.
Questions
Will it stretch my image?
Not unless you ask it to. Setting one dimension and leaving the other blank keeps the proportions. Setting both offers a choice of fitting inside, filling and cropping, or stretching to match exactly.
Can I make an image larger?
You can, and it will be soft. Enlarging invents pixels that were never captured, so it adds size without adding detail. There is a switch to prevent it happening by accident.
Does it resize a whole folder to the same size?
Yes. Add as many as you like and every one is resized on the same rule, which is the usual reason for using this rather than an editor.
What size should a web image be?
Twice the width it will be displayed at, to cover high-density screens, and rarely more than 2000 pixels on the long side for a full-width photograph.
