Resize image
Bring a photo down to a given width, a given height or a percentage of its size. The proportions are kept, so nothing is stretched. JPG, PNG, WebP and AVIF stay in their format; HEIC photos from an iPhone come back as JPG.

Frequently asked questions
Which formats can I resize?
JPG (JPEG), PNG, WebP, AVIF and HEIC or HEIF photos from an iPhone. JPG, PNG, WebP and AVIF keep their format; HEIC and HEIF are delivered as JPG.
Will the image be distorted?
No. You give one dimension, or a percentage, and the other dimension is computed from the original proportions.
Can I set both a width and a height?
This page takes one side at a time to keep the proportions. To fit an image inside a box, give the width or the height, whichever is the tighter limit. The Options panel of the image converters accepts both values and fits the image inside them.
Is the quality kept?
Making an image smaller keeps it sharp: pixels are resampled with a high quality filter. JPG, WebP and AVIF are re-encoded at a high quality setting, and PNG stays lossless.
Can I resize images from code?
Yes. The resize operation of the ConvertFly API takes a width, a height or a percentage. See the API documentation.

Width, height or percentage
Give the side that matters to you: a width of 1200 pixels for a blog, a height of 1080 for a slide, or 50 percent to halve a batch of photos. The other dimension is computed to keep the proportions, so faces and shapes are never distorted.
Same format, same orientation
A JPG comes back as a JPG, a PNG as a PNG, with its transparency. A HEIC or HEIF photo comes back as a JPG, which opens on every device. Phone photos store their orientation in metadata: it is applied before resizing, so the picture is never turned on its side. Location and camera metadata are removed.
Enlarging an image
A percentage above 100, or a size larger than the original, makes the image bigger. Pixels are interpolated, so a small picture does not gain detail: enlarge moderately, and prefer the original file when you have it.
Need a smaller file rather than a smaller picture?
Resizing cuts the file size a lot when the picture gets smaller. To keep the dimensions and only reduce the weight, use the Compress image tool. To change the format, see the converters below.
