## Tools

- [All tools](https://apps.hex.pro/tools): Small single-purpose tools from Hex Pro that run entirely in your browser. Source published, nothing transmitted, and each one keeps working offline.

- [HEIC to JPG converter](https://apps.hex.pro/tools/private-heic-to-jpg-image-converter): Turn an iPhone HEIC photo into a JPG that every program opens. HEIC to JPG runs in your browser, so nothing is uploaded and no account is needed.
- [HEIC to PNG converter](https://apps.hex.pro/tools/private-heic-to-png-image-converter): HEIC to PNG gives a lossless copy that Windows and every editor will open, with the colour profile kept. It happens in this tab and nothing is uploaded.
- [HEIC to WebP converter](https://apps.hex.pro/tools/private-heic-to-webp-image-converter): Convert HEIC to WebP for a smaller file that browsers and editors open. The work happens in this tab, so nothing is uploaded. Not available in Safari.
- [PNG to JPG converter](https://apps.hex.pro/tools/private-png-to-jpg-image-converter): PNG to JPG cuts the file size for uploads and email. Transparency is flattened and the conversion runs in your browser, so nothing is uploaded to a server.
- [JPG to PNG converter](https://apps.hex.pro/tools/private-jpg-to-png-image-converter): JPG to PNG stops the quality loss that comes with re-saving a JPEG. The conversion happens in your browser on your own machine, and nothing is uploaded.
- [WebP to PNG converter](https://apps.hex.pro/tools/private-webp-to-png-image-converter): WebP to PNG makes a saved web image usable in editors and older software, with transparency kept. It runs in your browser and nothing is uploaded anywhere.
- [WebP to JPG converter](https://apps.hex.pro/tools/private-webp-to-jpg-image-converter): Convert WebP to JPG in the browser tab, with nothing uploaded. Transparency is flattened because JPEG has no alpha, and metadata is removed by default.
- [PNG to WebP converter](https://apps.hex.pro/tools/private-png-to-webp-image-converter): Convert PNG to WebP in your browser tab, with nothing uploaded. Transparency is kept and files come out much smaller. Not available in Safari.
- [JPG to WebP converter](https://apps.hex.pro/tools/private-jpg-to-webp-image-converter): Convert JPG to WebP inside your own browser tab. Nothing is uploaded, and WebP compresses the same photograph further than JPEG can at a matching quality.
