Resize a picture, then see if it needs to be smaller still
- Pixels or percent
- A quality slider
- 50 at a time
- Never leaves your device
Type the width you need, or a percent, and drop the photos in. Drop a single photo and you can drag its corner instead, with the file size worked out each time you let go. The result shows the old and new size in pixels and in kilobytes, and if it is still too heavy for where it is going, one more press writes it smaller.
Two numbers, one shape
Type a box and every photo fits inside it without being squashed. Untick Keep proportions only when an exact size matters more than the shape.
The size you actually got
Before and after, in pixels and in KB, straight from the file that downloads. A result that came out larger says so.
Smaller, one step at a time
No guessing a quality number up front. Look at the result, and press again only if it needs to go lower.
Straight from an iPhone
HEIC photos open right here and stay the right way up, so a camera-roll picture needs no export first.
Pixels or percent
By pixels is for a size someone else set: a website asking for 1200 wide, a profile picture at 400 by 400, a slide that wants a 1920 by 1080 background. By percent is for when the only goal is lighter: half the width means a quarter of the pixels, and the kilobytes fall with them.
With Keep proportions on, the two fields describe a box the picture must fit inside. Fill in only the width and the height is left to follow; fill in both and the picture stops at whichever side reaches its limit first. That is also what makes one setting safe for a mixed batch of tall and wide photos.
Why quality matters as much as pixels
Two files with the same width and height can differ in weight several times over, because the encoder decides how much fine detail to keep. The slider sets that, and its resting point is chosen so that a photo viewed at its normal size looks the same as before. Screenshots with small text are the exception worth checking: their sharp edges are the first thing low quality blurs.
Frequently asked questions
How do I resize a photo to 1080 pixels wide?
Choose By pixels, type 1080 in Width and leave Height empty. With Keep proportions on, the height follows the photo’s own shape, so a 4032×3024 phone picture comes out 1080×810.
What does the quality slider change?
How hard the picture is squeezed when it is written. The resting point of 82 shows no difference you can see at normal size. Slide left for a smaller file at the cost of soft edges on text and fine lines; slide right only if the picture will be printed or zoomed into.
The file is still too big. What now?
Press Make it smaller on the result. It writes the same pixels again at a lower quality and shows the new size, and you can press it again. At quality 30 it stops and says so, because below that a photo starts to break into blocks; past that point, fewer pixels is the way to a smaller file.
Can I resize several pictures at once?
Up to 50 in one drop. Every picture gets the same setting, and with Keep proportions on each keeps its own shape inside the box you typed, so a mix of portrait and landscape shots all come out right. They download together as one ZIP.
Why did my PNG come back as a WebP?
A PNG has no quality setting, so neither the slider nor Make it smaller could do anything to it. WebP has one and keeps see-through areas see-through. iPhone photos are saved as WebP as well, since no browser can write HEIC. JPG stays JPG.
Can it make a picture bigger?
Yes, up to 400% or 10,000 pixels on the longer side. Enlarging cannot add detail that was never captured, so the result looks soft, and the file usually grows; the result line shows that plainly rather than hiding it.
Is the photo sent anywhere?
No. The picture is opened, redrawn at the new size and written out by this page in your own browser. The location and camera details stored inside a phone photo are not copied into the resized file.
