Photo size reducer
Big photos from your phone or camera, shrunk in seconds. Compression runs in your browser, so originals stay private. Trying to email large photos? Shrink them here first.
How to use the photo size reducer
Reduce image size without losing quality
Most of the weight in a phone or camera photo is detail your eyes never see on a screen. The photo size reducer re-encodes each image at a quality level chosen to look the same at normal viewing size, and keeps the width and height exactly as they were. The result is a much lighter file that still shows every face, sign and texture clearly, because what goes is the invisible part of the data, not the picture.
Quality only drops if you push the same file through compression again and again. Each JPG save throws a little more away, so always start from the original rather than compressing a copy of a copy. The reducer never touches your original file: it makes a new, smaller copy and leaves the source exactly where it was on your device.
This is also why the reducer works well on photos straight from a phone or camera. Those files are saved quickly by the device, often at a very high quality setting, and carry far more data than a screen needs. Re-encoding them once, carefully, removes that surplus in a single step.
Reduce photo size for email, forms and websites
Every destination has its own idea of too big. Email providers cap the size of a whole message, so a few full-size photos can fill it. Online forms for visas, job applications and school portals often state a hard limit per file and reject anything over it. Websites do not refuse big photos, but every extra megabyte makes the page slower, especially on a phone connection.
For email and websites, compressing alone is often enough to get a photo well under the limit. For a strict form limit, compress first, check the size shown next to the file, and if it is still too big, resize the photo to fewer pixels with the Resize tab and compress again. You can drop up to 30 photos at once, up to 50 MB each, and download them together as a ZIP. Our guide on how to reduce photo file size goes through the targets for each case.
Smaller in MB or smaller in pixels?
These are two different kinds of small. Smaller in MB means the file takes less storage and travels faster, while the photo keeps its full dimensions; that is what this page does. Smaller in pixels means the picture itself has fewer pixels across, for example 1200 instead of 4000, which also cuts the megabytes, often by much more, but leaves less detail for printing or zooming in.
Choose by what happens next. If the photo might be printed, cropped later or viewed full screen on a large monitor, keep the pixels and only reduce the MB. If it will only be looked at in an email, a chat or a web page, reducing the pixels as well is the bigger win. When in doubt, compress first; you can always resize afterwards, but you cannot get pixels back once they are gone.
iPhone HEIC photos work here too: they are decoded in your browser and come back as compressed JPGs, which makes them smaller and lets them open on any computer at the same time.
