Frequently asked questions
What quality setting should I use?
Around 70 to 80 percent is a good starting point. Lower numbers make smaller files with more visible loss.
What does the largest side option do?
It limits the longest edge of the image in pixels, which makes large photos smaller as well as lighter.
Why was my image not made smaller?
If an image is already small, compressing it again may not help. In that case you get the original back with a note.
Does compression reduce quality?
Lower quality settings reduce detail to save space. Keep the quality high if you need the image to stay crisp.
Are my images uploaded?
No. Compression runs in your browser and the image stays on your device.
Can I compress PNG as well as JPG?
Yes. You can add common image files and set the quality and largest side.
Is Compress Image free to use?
Yes. Compress Image is 100% free, with no signup, no daily limit and no paid plans.
Do I need to create an account to use Compress Image?

Is it safe to use Compress Image with private or sensitive files?
Yes. Compress Image processes your file locally in your browser using client-side code. The file itself is never uploaded to Toolkitties' servers.
Does Compress Image reduce image quality?
