How to use
- Drag images into the box above or tap Choose files. Add as many as you like.
- Set the Quality. The default of 75 looks virtually identical while saving a lot of space. PNG is compressed by reducing colours.
- For large phone photos, set Max long side to about 1920 px to save far more. If you have an upload limit, enter it in Target size.
- Tap Save on each file or Save all (ZIP) when done.
Good to know
There are three main ways to make an image smaller: ① lower the JPG/WebP quality (70–80 is hard to tell apart on screen), ② reduce the dimensions (phone photos exceed 4000 px, but 1920 px is plenty for screens), ③ switch to the more efficient WebP format.
PNG is compressed by reducing the number of colours instead of a quality value. Logos, icons and screenshots usually look the same at 256 colours while often shrinking to half the size or less.
With a target size, quality is adjusted automatically until the file fits, and if it still does not, the resolution is reduced step by step — handy for application forms and shops with limits like "max 1 MB".
Everything is processed inside this browser. Files are never sent over the internet, and the saved results no longer carry metadata such as GPS location.
FAQ
Will the quality drop a lot?
The default of 75 is hard to distinguish from the original on screen. For printing, raise it to 85–90.
The compressed file got bigger.
Images that are already heavily compressed can grow when re-saved. In that case the original is returned unchanged.
What settings are good for email or chat?
A long side of 1920 px at quality 75 looks great on screens and usually ends up at a few hundred KB.
Are my images uploaded?
No. Compression and resizing run entirely in your browser on your own device. Your files never leave it.
