Compress images
Make photos small enough for an email, an upload form or a website. You see the new size before you download, and the original is never changed.
How to use it
- Drop in one or more images.
- Pick a quality level. Setting a maximum width as well saves the most space on large phone photos.
- Click Compress, check the new sizes, and save.
Questions
How small can I get a photo without it looking worse?
A quality around 70 usually looks the same as the original on screen. Limiting the width to 1920 pixels shrinks a 12-megapixel phone photo from several megabytes to a few hundred kilobytes.
Why did my PNG barely shrink?
PNG is lossless, so there is little to remove without changing the format. Choose WebP, or JPG if the image has no transparency, for a much smaller file.
What if the compressed file comes out bigger?
That can happen when an image was already well compressed. If the format and size stay the same and the result would be larger, you get your original file back unchanged.
Do my files get uploaded?
No. The page does the work inside your browser, and your files are never sent to a server. That makes it fine to use with private documents such as contracts or bank statements.
