Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

The tool uses HTML5 Canvas to scale your original photo into the background with a hardware-accelerated Gaussian blur filter, while neatly fitting the sharp foreground photo on top with zero distortion.
Instagram Post / Profile: 1:1 (1080×1080 px); Instagram Portrait Feed: 4:5 (1080×1350 px); Stories, Reels, TikTok, and YouTube Shorts: 9:16 (1080×1920 px); YouTube Thumbnails and Twitter/X Feed: 16:9 (1920×1080 px).
In 'Fit with Blurred Background' or 'Fit with Solid Padding' modes, your entire original photo is 100% preserved with zero cropping. In 'Fill & Center Crop' mode, the image is zoomed to fill the target aspect ratio.
All exported images are generated at full target resolutions (e.g., true 1080×1920 for Stories, 1920×1080 for YouTube), ensuring crisp, professional quality on all screens.
Never. 100% of the canvas padding, blurring, and rasterization occurs entirely inside your browser memory. Your images never leave your device.
