100% private — your images are compressed on your device and are never uploaded to any server.
Works with images up to about 60 MB each. GIFs are converted using their first frame. On an older phone, very large images may be slow.

How it works
Pick the quality
Balanced is right for most photos. Lower it for the smallest file, raise it to keep every detail.
Compare and download
Check the before-and-after view, then download each file or all of them as one ZIP.
How image compression works
A photo from a modern phone weighs several megabytes, far more than a web page, an email or a form usually needs. Compressing an image means storing it in fewer bytes. There are two ways to do that. Lossless compression rebuilds the exact same pixels and saves little. Lossy compression, which is what JPG and WebP use, throws away detail the eye barely notices and saves a lot. This tool uses the lossy approach, and the quality slider decides how much detail is kept.
Which quality should you choose?
For photographs, a quality around 75 is the usual sweet spot: files are often several times smaller and the difference is hard to see at normal size. Around 90 it is close to indistinguishable from the original, and below 50 the blocky artifacts start to show, especially around text and sharp edges. Use the before-and-after view to judge with your own image rather than trusting a number.
The biggest saving is usually the size, not the quality
A 12-megapixel phone photo is about 4,000 pixels wide, while a page rarely displays an image wider than 1,600 to 2,000 pixels. Reducing the largest side to 1920 px often cuts the file size by more than any quality setting, with no visible loss on screen. The "Largest side" option does exactly that and never enlarges a smaller image.
JPG, PNG or WebP?
- JPG is the right choice for photographs and is accepted everywhere.
- PNG is lossless, so its size barely changes with this tool. It suits logos, screenshots and images with transparency. If you need a much smaller file, convert a photo from PNG to JPG or WebP.
- WebP gives the same look as JPG at a smaller size and supports transparency, but a few older programs cannot open it.
When it will not help
An image that is already well compressed cannot be squeezed much further, and recompressing a JPG repeatedly only adds damage. In that case the tool tells you and keeps the original file rather than giving you a bigger or blurrier one. As a side effect, the saved copy carries none of the original camera metadata, such as the location where a photo was taken.
Frequently asked questions
Does compressing an image reduce its quality?
With JPG and WebP a little detail is discarded, but at a balanced setting the difference is hard to notice. The before-and-after view lets you check it on your own image. PNG is lossless and keeps every pixel.
Are my images uploaded to a server?
No. They are compressed inside your browser, on your own device, and are never sent over the internet.
What quality setting should I use?
Around 75 for general use. Choose 90 when appearance matters most, such as a portfolio, and 50 or lower when you need the smallest possible file and can accept some softness.
Why did a file not get smaller?
It was probably already well optimized, or it is a PNG. The tool keeps the original in that case. For a real reduction, lower the largest side or convert the PNG to JPG or WebP.
Can I compress many images at once?
Yes. Drop as many as you like and download them individually or as a single ZIP file.
Can I get an image under an exact size, such as 200 KB?
Use the tool that starts from the limit: make an image fit under an exact size. You type the maximum size and it finds the best quality that fits.
Does it remove the photo's location and camera data?
Yes, the compressed copy is rebuilt from the pixels only, so metadata such as GPS location is not carried over.
