What FromHEIC is
FromHEIC is a set of tools for working with HEIC photos, the format most recent iPhones save by default. You can convert HEIC to JPG, PNG, WebP, AVIF, TIFF or PDF, view and inspect files, read or remove metadata, resize and compress, and convert other images back to HEIC where your browser allows it.
Every tool runs in your browser. Your files are not uploaded to a server, because the site has no server-side processing.
What it deliberately does not do
- There are no accounts and no sign-in.
- There is no file storage on our side. Files exist in your browser’s memory while the page is open, and closing or refreshing the page discards them.
- There is no tracking at launch. See the Privacy and Cookies pages for what the site does and does not store.
Who runs it
The site is operated by Hammer Desenvolvimento de Software. For questions, use the details on the Contact page (contact@gohammer.mobi). We do not publish a team list or a company history here, because there is nothing accurate to add beyond the owner details above.
How the content is written
Guides and tool pages aim to be specific about what each tool does and does not do, including limits and side effects such as extra quality loss when converting to JPG. Claims about third-party products and standards are linked to a primary source, and when we could not verify something we say so instead of guessing. The Editorial policy page explains the review process and how to report a mistake.
What we ask of you
Check results before relying on them, keep your original files, and read the notes on each tool page. Browser tools depend on your device’s memory and browser, and very large files may fail.
