No — blurring runs on local canvas and bakes into exported pixels. The page opens the full photo editor with the Blur tool armed. Exception: the optional AI Describe button sends a small downscaled preview to Gemini (1 credit, stated on the button).
Not from our exports: pixel blocks floor at 8px and bake into the file — there is no layer to peel. For absolute certainty use the solid black Cover tool instead.
No — you drag over each face yourself. That keeps it free, instant, and private (no face-detection model, no server). Face-count checklists: zoom the export before sharing.
Both are safe here at our floors; Cover (solid black) is safest of all. Never trust sub-8px mosaics from other tools — they can be partly reversed.
Add Text to Photo
Add one custom text caption onto a photo with color, size (10–300px slider), and X/Y position controls, composed on fixed social-size canvases — Instagram Post 1080×1080, Reel 1080×1920, YouTube Banner 2560×1440, Twitter Header 1500×500, or Custom. Exports PNG locally in your browser on Canvas; 3 free downloads a day.
Batch Image Editor
Downscale a batch of images to one max width (default 1920px) with an optional bottom-right watermark, then download everything as a ZIP. Same max-width and watermark apply to every image — local Canvas work, 3 free images a day.
Compress Image to 50KB
Shrinks one photo to under 50 KB (51,200 bytes) for portals with strict limits — NSDL, UIDAI, UPSC, SSC, and banking uploads. Runs up to 5 auto passes locally with the browser-image-compression library; standard metadata is preserved.

Background Remover
Segments the foreground subject from an image using a neural network, producing a transparent PNG with clean edges. Handles hair, fur, and semi-transparent regions better than chroma-key or magic-wand selection. Max 50MB.
