The collection covers two areas that matter most for website owners and content creators: technical SEO tools for analysing and optimising your site's search performance, and image converter tools for handling the format conversion needs that come up constantly in day-to-day web and content work.

Image Converter Tools — For iPhone Users, Bloggers & Developers
The image converter tools solve the most common format friction in web and content work. All 9 run entirely in your browser — your images are never uploaded to any server, conversion is instant, and there are no file count or size limits.
The most common use case is iPhone photos. Every iPhone running iOS 11 or later shoots in HEIC format by default — a format most websites, Windows apps, and Android devices can't open natively. Converting to JPG, PNG, or WebP takes seconds, and the resulting files work everywhere without plugins or special software.
| Tool | Best use case | Link |
|---|---|---|
| HEIC to PNG | iPhone photos → lossless PNG for editing | Use → |
| HEIC to JPG | iPhone photos → small shareable files | Use → |
| HEIC to WebP | iPhone photos → web-optimised for blogs | Use → |
| HEIC to PDF | iPhone photos → document submissions | Use → |
| HEIC Converter | All HEIC output formats in one tool | Use → |
| WebP to JPG | Web images → universal offline use | Use → |
| WebP to PNG | Web images → lossless with transparency | Use → |
| PNG to JPG | Large PNGs → smaller shareable files | Use → |
| JPG to PDF | Multiple photos → one PDF document | Use → |
Why Image Format Matters for SEO
Image format choice directly affects page speed, and page speed is a confirmed Google ranking factor. For website owners and bloggers who publish image-heavy content, switching from PNG or JPG to WebP typically reduces image file weight by 25–35% — which improves Largest Contentful Paint (LCP), one of the three Core Web Vitals metrics Google uses in its ranking algorithm. The image converters here make that a straightforward, 10-second process rather than a multi-step workflow requiring desktop software.
