Blur Background
Keep the subject sharp and soften everything behind it.
What Does Background Blur Do?
The Blur Background tool detects the main subject of your photo and applies a soft, natural blur to everything behind it, recreating the shallow depth-of-field look of a portrait-mode camera or a wide-aperture lens, even on photos taken with a regular phone camera.
How to Blur a Background in 2 Steps
- Upload your photo (JPG, PNG or WEBP) using Choose File or drag-and-drop.
- Click Blur Background and download the result: subject sharp, background softly blurred.

Frequently Asked Questions
How is background blur different from background removal?
Background blur softens and darkens the area behind the subject while keeping it visible, similar to a camera's portrait mode. Background removal deletes the background entirely, leaving transparency.
Does this tool work without a real camera depth sensor?
Yes, RetroifyMe's AI detects the subject in a single flat photo and applies a synthetic blur to everything else, so no special camera or depth data is required.
Can I control how strong the blur is?
The tool applies a natural, portrait-style blur by default; for a different intensity, re-run the tool or combine it with the compression tool afterward for softer detail.
What kind of photos work best with background blur?
Photos with a clear single subject (portraits, product shots, pet photos) work best, since the AI needs to distinguish the subject from the background.
Is blurring a background free on RetroifyMe?
Yes, it's completely free with no watermark and no account required.
General Questions
How do phones create the portrait mode blur effect?
Phones typically use depth data from multiple lenses or AI subject detection to separate the subject from the background before blurring it. RetroifyMe recreates this effect from a single uploaded photo using AI.
Can I apply a retro effect and then blur the background?
Yes: apply a retro or vintage effect first, download the result, then run it through Blur Background for a stylised, softened look.
