Frequently Asked Questions
How do I resize an image?
Choose your images, then resize by percentage (like 50%) or type a width or height in pixels. The other side adjusts automatically to keep the shape. Download each image or a ZIP.
Will the image be stretched?
No, if you set only width or only height. If you set both, the image is stretched to exactly that size; set one side to keep the proportions.
Can I make an image bigger?
Yes, up to 400%, but enlarging can't add real detail, so big enlargements look soft.
What about a size limit in KB?
Use resize image in KB: it reaches a KB limit while keeping the most quality.
Are my images uploaded?
No. Resizing runs in your browser.
