How do I convert HEIF to WebP?

Add your HEIF file to the upload area above, then press Convert. The WebP file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WebP reduce quality?

WebP uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

HEIF to WebP Converter

Turn HEIF files into WebP in a couple of clicks. The container standard HEIC is built on. Modern web format, ~30% smaller than JPG at similar quality. The output is re-encoded, so quality depends on the settings you choose.

HEIF and WebP explained

HEIF is the underlying container standard that HEIC is a specific profile of. The distinction matters mainly to developers: HEIF describes the box structure, while HEIC specifies HEVC-compressed contents inside it.

WebP is a Google-developed format that offers both lossy and lossless modes, transparency, and animation in one container. In its lossy mode it typically produces files around 25–35% smaller than JPEG at comparable visual quality.

Where HEIF files come from: Newer cameras and some Android devices, alongside Apple's HEIC.
Where WebP is used: Modern websites, and increasingly the default export from web-focused design tools.

HEIF vs WebP

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

HEIF compared with WebP
Property	Source	Target
Compression	Lossy	Lossy or lossless
Transparency	Yes	Yes
Animation	Yes	Yes
Introduced	2015	2010
Browser support	Limited outside Apple and newer Android.	All modern browsers. Some older desktop apps can't open it.

HEIF is stronger at: Efficient modern compression. Flexible container that can hold image sequences and metadata.
WebP is stronger at: Substantially smaller than JPEG at similar quality. Supports transparency, which JPEG cannot. Supports animation, replacing GIF at a fraction of the size.

Why convert HEIF to WebP?

People make this switch when they run into the limits of HEIF: you need to share the file with anyone. WebP is the better fit when you are publishing images on a website and want smaller files without a visible quality drop.

HEIF limitations that prompt the switch: Support outside Apple and recent Android is limited. Confusing overlap with HEIC in practice.
What you give up: Desktop applications and older software often cannot open it. Some photo printing services and older phones reject it.

Does converting HEIF to WebP reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

WebP is not always smaller. For simple graphics with few colours, a well-optimised PNG can still win.
