Your compressed image is ready
Download ImageTip: PNG is a lossless format, so the quality slider mainly changes JPG and WebP files. For a much smaller photo, turn the PNG into a JPG with the Image Format Converter.
How to use the Image Compressor
- Drop an image into the upload area or click to browse.
- Move the quality slider and watch the estimated new size update.
- Compare the original and compressed sizes, then download the result.
Image Compressor FAQs
Are my images uploaded to a server?
No. Compression runs entirely in your browser — your images never leave your device.
Which formats can I compress?
JPG, PNG and WebP images. The output keeps the same format as the original.
Will compression reduce image quality?
Lower quality settings make smaller files with some visible loss. The live preview and size estimate help you find the right balance — 75 to 85 is a good starting point for photos.
Is there a file size limit?
There is no fixed limit, but very large images depend on your device memory. If a huge image fails to load, try a smaller copy.
Why did my PNG not get much smaller?
PNG is lossless, so re-encoding saves little. Converting the PNG to JPG or WebP with the Image Format Converter usually shrinks photos far more.
