Frequently asked questions
Is Image Transparency Checker free to use?
Yes. Image Transparency Checker is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Image Transparency Checker upload your image to a server?
No. Image Transparency Checker processes your image inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Image Transparency Checker.
Do I need to install anything to use Image Transparency Checker?
No installation is needed. Image Transparency Checker runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Image Transparency Checker on a phone or tablet?
Yes. The Image Transparency Checker interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your image when I close the tab?
It is discarded. Image Transparency Checker keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
