An all-in-one image crop/split/collage tool (no uploads, no watermark)

Hi HN,I rebuilt my side project into a small “all-in-one” image toolbox: https://imagesplitter.toolsThe part I’m most proud of (and personally use the most) is the collage workflow:1. Grid collage (templates + merge cells for “one big + many small” layouts)2. Long-image stitching (great for screenshots / step-by-step guides / chat logs)3. Freeform collage (DIY your own grid layout — split/merge cells however you want — then apply that layout to the grid collage)My motivation was pretty simple: I kept bouncing between different sites for basic image chores, and many of them add watermarks, require login, or feel sketchy for privacy. So I made this with a few strict rules:1. Free, no watermark 2. Privacy-first: processing happens locally in the browser (no upload/storage)Besides collages, it also includes common utilities I often need:crop (free/aspect/circle/shape), grid split + ZIP export, batch convert (JPG/PNG/WebP/ICO…), compress, images→GIF, text/markdown/html→image, QR generate/decode, color picker, image info, etc.I’d really love feedback:1) What’s the most annoying part of making collages / long images?2) Any “must-have” features you’d expect for this kind of tool?Thanks for taking a look — happy to iterate based on your comments.
