prezll is a free, browser-based editor for photos and GIFs made for social media. One-click crop presets for Instagram, Threads, and X, plus filters, mosaic/blur, stickers, and text. The GIF editor trims, resizes, and compresses clips down to size. Everything processes locally — nothing is ever uploaded to a server — and you can strip a photo's EXIF metadata (location, device info) without any quality loss. No sign-up, no watermark, completely free.
