Frequently Asked Questions
How do I blur the background of a photo online for free without signing up?
Select 'Background Only' blur mode, upload your photo, and AI automatically detects your subject and blurs only the background — no masking needed. Download instantly. 100% free, no account, no watermark.
How do I blur or censor a face, licence plate, or sensitive text in a photo?
Switch to Paint Blur mode and brush directly over the area to censor. Adjust brush size for precision and set blur strength to 80–100% for a solid pixelate effect. No signup, works on any device.
Can I blur the background without Photoshop — free online?
Yes. MinifyCloud's AI background blur gives a professional depth-of-field effect with no Photoshop or software needed. Upload, select Background Only mode, adjust blur strength, and download in seconds.
What is the difference between full-image blur and background-only blur?
Full-image blur softens the entire photo equally — good for backgrounds or censoring content. AI background blur keeps your subject pixel-sharp while blurring only the background for a portrait-mode effect.
What blur strength should I use for different effects?
Portrait bokeh (natural): 30–50%. Studio depth-of-field (dramatic): 60–80%. Censor/pixelate for privacy: 80–100%. Higher values in Paint Blur mode create a mosaic-style pixelate ideal for faces and plates.
Does the blur tool work on Mac, iPhone, Android, and Windows?
Yes — MinifyCloud's blur tool runs in any browser with no software to install. Background AI blur runs client-side for full privacy. Works on Chrome, Safari, Firefox, and Edge on any device.
