FAQ

Frequently Asked Questions

Everything you need to know about Prezll, privacy safety, and social media image optimization.

QAre my uploaded photos or videos stored on your servers?

No. Prezll processes everything 100% locally in your browser memory via HTML5 Canvas. Your media files are never transferred or stored on any external server.

QWhy do photos look compressed or blurry on Instagram?

Instagram's server aggressively recompresses images that exceed 1080px width or don't match standard ratios. Cropping to exact 1080x1350 (4:5) in Prezll prevents algorithmic quality loss.

QCan I use edited images for commercial business and advertising?

Yes, 100% commercial use is permitted. All included fonts are open-source and free for commercial use. No watermarks are ever added.

QWhy is 4:5 vertical portrait ratio better than 1:1 square?

On mobile displays, 4:5 takes up 25% more vertical feed area than 1:1. Users spend more time viewing your post as they scroll, signaling higher engagement to the algorithm.

QHow does Prezll remove GPS location and EXIF metadata?

Prezll automatically strips the EXIF header containing GPS coordinates and camera serial numbers directly in memory upon file loading.

QCan I also edit Videos and animated GIFs?

Yes! Use the Video and GIF links in the top header to trim, crop, resize, and blur videos up to 100MB and GIFs up to 20MB completely free.

QDoes it work smoothly on mobile smartphone browsers?

Yes. Fully optimized for touch gestures on mobile Safari (iOS) and Chrome (Android) without requiring any app store downloads.

QIs it truly free without registration or hidden credit cards?

Prezll requires zero sign-up, zero logins, and zero credit card entries. Instant editing and unlimited high-res downloads forever.
