How resizing works
Pick how you want to size the photo, then drop it in. Change a setting and every photo on the page is redone at once. Proportions are always kept, so nothing gets stretched. The photo keeps its kind: a JPG stays a JPG, a PNG stays a PNG. iPhone (HEIC) photos: convert them to JPG first, on the HEIC to JPG page.
How to use it in 4 steps
- 1Choose how to size the photo: Longest side, Percent, or Width × height.
- 2Type the number you want, or press one of the quick sizes.
- 3Drop your photos onto the box. Each is resized at once.
- 4Change the number and every photo on the page is redone. Press Save, or Save all as one zip.
Why resize a photo
Phone and camera photos are far bigger than most places need. A website, a social post, an email or a form with a size limit usually wants a smaller picture. Making a photo smaller in pixels also makes the file smaller, so it uploads faster and uses less data.
Three ways to choose the size
You can set the longest side in pixels, scale by a percentage, or fit the picture inside a width and height. The longest side is the simplest for most jobs: set it once and both portrait and landscape photos come out right. The fit option keeps the shape of the picture, so nothing is stretched.
Making a photo larger
You can enlarge a photo, but this cannot add detail that was never captured, so a big enlargement looks soft. For printing, start with the largest original you have. For the web, it is almost always better to make pictures smaller than larger.
After resizing
If the file is still too big, run it through Compress photo. If you need a specific shape, use Crop & rotate first and then resize. Your original is never changed; you get a copy.

A quick example: a holiday photo for an email
A photo from a modern phone may be 4032 by 3024 pixels and 3 to 5 MB. Set Longest side to 1920 and it becomes 1920 by 1440 pixels, which is plenty for a screen and usually well under 1 MB. Choose 1080 instead and you get 1080 by 810, a good fit for social media.
Percent works the same way: 50 per cent of 4032 by 3024 gives 2016 by 1512.
Good to know
Decide the size from where the picture is going, not from habit. A screen needs far fewer pixels than a printer, so use the larger 3000 setting for pictures that will be printed. A JPG stays a JPG and a PNG stays a PNG, and the longest side can go up to 10,000 pixels. Try to resize once from the original, because resizing a picture that was already shrunk loses detail. iPhone HEIC photos need turning into JPGs first.
If you are preparing photos for a website, resizing is usually the biggest saving available. A 1920-pixel image is plenty for a full-width picture on most screens, and half that is enough for a column of text. Once resized, run the result through Compress photo if you still need a smaller file.

Questions people ask
What does Longest side mean?
It is the length of the longer edge of the photo, in pixels. If you enter 1920, a wide photo becomes 1920 pixels across and a tall photo becomes 1920 pixels high. The other edge follows, so nothing is squashed.
Which size should I pick?
640 is small, good for messages and email. 1080 suits most social media. 1920 fills a full-HD screen. 3000 keeps plenty of detail for printing small pictures.
Will my photo be stretched?
No. The shape of the photo is always kept. With Width × height, the photo is made as large as it can be while still fitting inside the box you describe.
Can I make a photo bigger?
You can, up to 10,000 pixels on the longest side, but making a photo bigger cannot add detail that was not there, so it will look soft.
What kind of file do I get back?
The same kind you put in: a JPG stays a JPG, a PNG stays a PNG. For an iPhone (HEIC) photo, convert it to JPG first with HEIC to JPG.
Does it change my original?
No. You get a new file and the original is untouched.
