We pick the best one for you: JPG for normal photos and WebP if the image has a transparent background.
How does it reduce the size without losing quality?
It uses the same encoders as Squoosh, Google's tool: MozJPEG for JPG, libwebp for WebP and OxiPNG for PNG. They remove information the eye doesn't notice and the photo's hidden data (GPS location, phone model).
What reduces the size the most is the size: a phone photo measures 4000 px or more, and for WhatsApp, a website or a PDF catalog 1280–1920 px is enough. With that and “High” sharpness (80), a 4 MB photo usually ends up at 200–400 KB.
Frequently asked questions
Are my photos uploaded to the internet?
No. Everything is processed on your phone or computer; the photos never leave your device.
Which format should I use?
JPG if you're going to send it or upload it anywhere. WebP is smaller and almost all apps open it. PNG only for screenshots or logos with few colors.
How do I get a photo under 1 MB or 500 KB?
Choose “Make it smaller than…” and type the limit in KB (1 MB = 1024 KB). We give you the sharpest possible photo without going over that size.
What does the sharpness number mean? Is it a percentage?
It isn't a reduction percentage. It's an encoder scale from 1 to 100: higher looks better but weighs more. Between 70 and 85 (“High”) the photo looks the same to the naked eye and weighs much less; at 30 it weighs very little but you'll notice small blotches.
Can I compress iPhone HEIC photos?
It depends on the browser: Safari opens them; in other browsers, first share them as JPG from the iPhone.
