About this tool
Use Image compressor with confidence.
Image compression reduces storage and transfer size by changing dimensions, encoding quality or both. The right setting depends on where the image will be used: a website thumbnail needs far fewer pixels than a printable photograph.
Work from a copy and compare the result at its expected display size. Small text, sharp edges and smooth gradients tend to reveal compression artifacts before ordinary photo detail does.
Common uses
Reduce large camera images before attaching several of them to one message.
Lower transfer size while keeping the dimensions appropriate for the page layout.
Optimize source images before combining them into a smaller PDF packet.
Practical tips
An image with excessive pixel dimensions can often be reduced cleanly before lowering quality aggressively.
Check fine text, faces and gradients rather than judging only from the percentage saved.
Repeatedly recompressing the same lossy file can gradually lower quality.
Questions about Image compressor
Why did a PNG remain fairly large?
PNG uses lossless compression. Detailed photographs often compress more efficiently as JPG or WebP, while PNG remains useful for graphics, text and transparency.
What quality setting should I use?
There is no universal number. Start high, inspect the intended display size and reduce quality only until the file meets your practical limit.
