Compress Image : what to know
A phone photo often weighs 3 to 8 MB, while many forms limit attachments to 1 or 2 MB. By reducing the width to 1920 pixels and the quality to around 75%, a photo usually drops below 500 KB with no visible difference on screen. The savings are shown for each image; WebP goes even further.
Frequently asked questions
What settings for a form limited to 1 MB?
Max width 1920 px and 75% quality: most photos end up under 500 KB. If that's not enough, choose 1280 px.
Is the compression visible?
Above 70% quality the difference is hard to see on screen. Small text and smooth gradients are the first to suffer below that.
Can I compress a PNG screenshot?
Yes: it is converted to JPG or WebP, which is much lighter. For a screenshot with fine text, keep quality at 85% or more.
Are my files uploaded to a server?
No. The conversion is done by your browser, on your computer or phone: your files are never sent over the Internet or kept by Tooleon. You can even go offline once the page has loaded.
Is it really free?
Yes: free, no sign-up, no watermark and no limit on conversions. The site is funded by ads.
