Hi Product Hunt — I built BulkMerge because most "quick" image tools turn a two-second job into an upload, a queue, and a privacy decision. BulkMerge keeps the work in the tab: merge images, resize animated GIFs, convert WebP to GIF, or compress a GIF under a size limit. There is no upload endpoint, no account, and no file retention. The trade-off is that a browser tab is not a render farm: GIF's 256-color limit and device memory still apply, and the page says so instead of pretending otherwise. I'll be around to answer questions about browser-side GIF encoding, OffscreenCanvas, or the compression presets. If you try it, I'd love to know which tool you used and what file size you were trying to hit.
