Resize a photo
Turn iPhone HEIC photos into JPG, PNG, WebP or AVIF — up to 200 at a time, with each format’s real size measured on your own photo before you choose. Runs in your browser: nothing is uploaded, and a JPG keeps the date the picture was taken.

Your browser would not let the file travel between pages (private mode does this) — open Convert Image and drop it there instead.
What happens to your file
It runs in this tab.
Your own browser does the work. Open the Network tab and watch it run: no request carries your file, and there is nothing on a server of ours to delete afterwards.
Two hundred photos at a time, no daily cap, and nothing is uploaded.
JPG and WebP lose a little detail each time; 200 photos or 500 MB per batch.
- No watermark The result is your file, unmarked. There is no paid tier that removes something we put there.
- No account Convert Image is exactly the same signed in or out. There is nothing to sign up for.
- No ads, no waiting No banners, no upsell pop-up, and no invented thirty-second queue standing between you and your download.
- Nothing to install It is a web page. The same one works on a phone: no app, no extension, no browser plugin.
- What it reads JPG · JPEG · PNG · WEBP · AVIF · GIF · BMP · HEIC · HEIF. Anything it cannot read is turned down with a reason on screen, not a silent nothing.

Six questions
Questions
Is Convert Image free?
Yes. Free, with no watermark, no account and no daily cap. It runs entirely in your browser, so there is nothing to meter.
Does my file get uploaded?
No. Everything happens in this browser tab, so the file never leaves your device. You can keep the Network tab open while it runs: no request carries your file.
Do I need an account?
No. This tool is exactly the same signed in or out.
Will it add a watermark?
No. The result is your file, unmarked. There is no paid tier that removes something we put there, because we do not put anything there.
Does it work on a phone?
Yes. It is the same web page, laid out for a small screen. Nothing to install, no app and no browser extension.
Are there ads, or a queue before the download?
No. No banners, no upsell pop-up, and no invented delay. When the job is done the file is ready.
