ProMetadata - Inject, edit & remove image metadata for SEO — free

Hey Product Hunt! 👋 I'm the maker of ProMetadata — and I want to tell you why I built this. I kept running into the same problem: I'd upload images to a client's CMS, and Google Image Search would completely ignore them. The images had zero metadata — no titles, no keywords, no descriptions. Every existing tool I found could only READ or REMOVE metadata. Nobody was solving the INJECTION problem for non-technical users. So I built ProMetadata. Here's what makes it different from every other metadata tool: → Inject metadata (EXIF, XMP, IPTC) into images and PDFs — nobody else does this online, free → SEO scoring — like Lighthouse, but for your image files → AI alt text generator — SEO-optimized alt text in one click → CMS webhook — auto-inject metadata when images enter your CMS → Bulk optimizer — compress + WebP convert + inject + rename in one pass → 14 tools total — viewer, cleaner, resizer, PDF parser, GPS map, sitemap generator and more Everything is free for single files. No login required. Works on any browser. I'd love your honest feedback on: Which tools would you actually use in your workflow? What metadata features are missing that you wish existed? Would you use the CMS webhook in a production pipeline? The roadmap is being shaped by real user feedback — every comment here directly influences what gets built next.
