HEIC to WebP Converter — Free, Private, No Upload
Turn HEIC photos into small, modern WebP files, right on your device. Nothing is uploaded, and there are no limits, ads or signups.
WebP is the natural target when you want HEIC's small file size but need something the whole web can display. It keeps photos compact — often smaller than a JPG at the same quality — while every current browser shows it without a plugin. It's an excellent choice for websites, blogs and anywhere you're watching your storage.
How to convert HEIC to WebP
- 1 Pick the HEIC photos you want to shrink — drop them on the box above or tap to browse.
- 2 The format is already set to WebP for smaller files — switch to JPG or PNG any time.
- 3 Grab each WebP, or export the batch as a single .zip. Your originals never left your phone.
Yes — because nothing is uploaded.
Most converters send your photos to a server you know nothing about. Filexum can't, because it never asks for them: the conversion runs inside your browser, on your own device. You don't have to take our word for it — open your browser's Network tab and watch it stay empty, or turn off Wi-Fi and convert anyway.

Why HEIC?
HEIC is the format Apple has used for iPhone and iPad photos since iOS 11 in 2017. It stores a still image inside the HEIF container using HEVC (H.265) compression — the same technology behind 4K video — which lets it hold a photo at roughly half the size of a JPG while keeping more detail, wider colour and extras like Live Photos and depth maps.
The catch is reach. Windows, many Android phones, older photo software and plenty of websites still can't open a .heic file without an extra plugin. Converting to a more universal format is usually the quickest fix — and on this page it happens entirely on your device, so the photos never leave it.
Why WebP?
WebP is a modern image format Google released in 2010, built to make photos smaller on the web without a visible drop in quality. It supports both lossy and lossless compression as well as transparency, and typically produces files noticeably smaller than an equivalent JPG or PNG.
Every current browser — Chrome, Safari, Firefox and Edge — displays WebP, so it's an excellent choice for websites and for saving space on your own device. A handful of older apps still don't accept it, so when maximum compatibility matters, JPG remains the safest bet.

HEIC to WebP — frequently asked
Is it private to convert HEIC to WebP?
Yes. The conversion is done by code on your own device; the HEIC file is never sent over the internet, which you can confirm by watching the browser's Network tab stay empty.
Do the HEIC files leave my device at all?
No — not the photo, its name or any fingerprint of it. The whole process is local, so it happily runs even with no connection at all.
Will WebP open everywhere?
Every current browser — Chrome, Safari, Firefox and Edge — shows WebP, so it works across the web and on modern devices. A few older apps still don't accept it; if you need maximum compatibility, convert to JPG instead.
Is WebP smaller than JPG?
Usually, yes. At a similar visual quality WebP files are typically noticeably smaller than the equivalent JPG or PNG, which makes it a great choice for websites and for saving space on your device.
Does the WebP converter cost anything?
No. It is free with no signup and no watermark. There is no premium plan, because there is no server bill for us to pass on.
How many HEIC photos can I turn into WebP?
As many as your device's memory allows. Convert a large batch and download all the WebP files together in a single .zip.
Will this run on my phone as well as my laptop?
Yes — on iPhone, Android, Windows and Mac alike, in any up-to-date Safari, Chrome, Firefox or Edge.
