Image Compressor
Shrink JPG, PNG and WebP files.
Runs entirely in your browser. Nothing you enter or upload leaves your device.
What the image compressor does
The image compressor re-saves JPG, PNG and WebP files at a quality level you choose, so they take up less space. Smaller images make web pages load faster, slip under the attachment limits of email and upload forms, and free up storage on your phone or server.
You can work on up to 30 images at once. Each one gets its own preview showing its new dimensions, its file size and how much smaller it became, and a total line adds up the saving across the whole batch.
How to use the image compressor
Make JPG, PNG and WebP images smaller without uploading them.
- Drop up to 30 images, or click to choose them.
- Adjust Quality. The slider runs from 10% to 95% and starts at 75%. Settings of 70–80% are usually hard to tell apart from the original.
- Optionally set a maximum width, which often saves more than lowering quality. Download images one by one or all together.
Tips
Every change you make re-compresses the whole batch, so you can move the slider and watch the sizes update before you download anything. Lower settings give smaller files, but at the bottom of the range you may see blocky patches in smooth areas such as skies and skin. Check the preview at the size you will actually use the image.
The Max width box only ever shrinks an image. Anything already narrower than the number you type keeps its size, and the height is scaled to match so nothing is stretched. Photos straight from a phone camera are often several thousand pixels wide, so a width close to where the image will be shown usually saves more than any quality setting.
Questions
What happens to PNG files?
With “Same as original”, PNGs are saved as WebP, which keeps transparency and is usually much smaller. If your browser can’t write WebP, they are saved as JPG instead. Choose JPG yourself for the widest compatibility (transparent areas become white).
Why is a file marked “already well compressed”?
When you keep the same format and size and the re-saved version would be no smaller, the tool hands back your original file untouched.
Can a compressed file end up larger?
Yes, if you change the format or set a maximum width. In those cases you always get the new file, and its card says how much larger it is so you can decide whether to keep it.
How are the new files named?
Compressed copies get -min added to the name, and the extension follows the output format, so logo.png saved as WebP becomes logo-min.webp.
Is photo metadata kept?
Not in re-saved images. Re-encoding drops EXIF data such as camera details and GPS location, which is often a privacy benefit. An original that is handed back unchanged still has its metadata.
Are my images uploaded?
No. They are processed in your browser.
