Image compressor: Smaller images. Same good looks.
Shrink photos and graphics for websites, email and uploads with a size limit. Free, no sign-up, and your images never leave your device. Mono, your little mate, keeps busy while they shrink and hops when they’re done.
Your images
Most photos look the same at 75 to 85. For PNGs, quality sets how many colours are kept.
The compressed copies leave out camera details and location. Changing a setting redoes them all.
Smaller images
Straight up, no catch
Never bigger
If an image can’t get any smaller, you get the original back, not a bigger copy.
Stays on your device
Your browser does the squeezing, so private photos and work files never leave your device.
Free, no account
No sign-up, no daily limit, no watermark, no “upgrade to download”.
No fake buttons
The download buttons are the real ones, right beside your images.
Ads in their own box
Ads keep the site free. Every one is labelled, hatched and kept well away from your images.
Good to know
How much smaller will my images get?
Photos from a phone usually shrink by 60 to 80 percent at quality 80, with no difference you’d notice. Making them smaller in pixels saves the most: a 4032-pixel-wide photo set to 1920 pixels has about a quarter of the pixels, so the file drops to roughly a quarter too.
Screenshots and graphics saved as PNG often halve. Images that a website or messaging app has already squeezed may barely change.
Which quality should I pick?
80 suits most things. Go up to 85 or 90 for photos you’ll print or show large, and down to 60 or 70 for thumbnails, email and pages that need to load fast.
To check, tap a picture in the list, then use “Hold to see the original” and “Zoom to 100%”. Differences show up first in skies, skin and fine text.
JPG, PNG or WebP: which one?
- JPG for photos. It opens everywhere. It can’t be see-through, so transparent areas turn white.
- PNG for screenshots, logos and anything with sharp text or a see-through background.
- WebP is usually smallest, and keeps see-through areas. Every current browser shows it, but some older apps and email programs can’t open it.
What happens to the photo’s details?
The compressed copies leave out the camera details, the time the photo was taken and any GPS location. That’s handy before you post or send a photo. If you need those details, keep the original as well.
Photos are turned the right way up first, so they still show the right way round without them.
Does it work with iPhone HEIC photos?
Yes. They come out as JPGs, or WebP or PNG if you pick one. The first time, your browser downloads the HEIC reader from this site (about 0.5 MB). To convert HEIC photos without compressing them, use HEIC to JPG.
Is there a limit?
Up to 200 images at a time, each as big as your device can handle. iPhones and iPads can’t draw images over about 16 megapixels, so bigger photos are made a little smaller there, and the list says so.
Are my images uploaded?
No. Your browser reads each image, makes the smaller copy and hands it straight to you. Nothing is sent to us or anyone else, and it’s all gone when you close the page.
