Can I blur several parts of one image?

Yes — up to 100 regions per image, each with its own style and strength. One pass covers a face here, a name there, and a screen in the corner.

Does the rest of the picture lose quality?

The export re-encodes the image — that's what makes the blur permanent and strips the metadata — but nothing outside your regions is filtered. For UI captures and text, export PNG to keep edges crisp; for photos, high-quality JPEG is indistinguishable in practice.

Can it blur the background of a photo?

That's the one job this page won't claim. Blurify is region-first: you mark what to hide. Softening everything except the subject is portrait-style background blur — a different kind of tool. What Blurify does do is cover any number of specific spots, sharply bounded, in any image.

Do I need an app on iPhone or Android?

No — the editor runs in the mobile browser on both, and regions are drawn with touch. No install, no account, no watermark on the export.

How precise can a region be?

As tight as you can drag it — a region can cover one word, one eye strip, one house number. If the job is many small text regions on a page, the Blur text in an image guide is the deeper walkthrough.

How it works for region.

Drop the image
JPEG, PNG, WebP, HEIC/HEIF — up to 20 MB. Anything Blurify recognizes — faces, plates, screens — is outlined for you on arrival.
Drag a box over the part to hide
Auto-suggestions are a head start; the point of this page is the rectangle you draw yourself — anywhere in the image, any size, up to 100 per photo.
Style it, export — the rest stays sharp
Gaussian, pixelate, or solid fill, set per region. Export re-encodes the image with your regions baked in and EXIF stripped; everything outside them keeps its detail.
