HEIF to WebP Converter

Turn HEIF files into WebP in a couple of clicks. HEIF is the container standard HEIC is built on; WebP is a modern web format, ~30% smaller than JPG at similar quality. Some detail is discarded to fit the target format; how much depends on the format and your settings.

How to use it

  1. 1

    Add your HEIF files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control quality and metadata removal.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your HEIF file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your HEIF file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Photographs carry more than what is in the frame — most also carry the time, the device and often the GPS coordinates where they were taken. It matters more than it sounds, because of what images usually are:

Photos of ID cards and licences

the usual way people send identity documents

Screenshots of bank transfers

account details, and proof of what you paid whom

Medical scans and photographs

X-rays, results, images of a condition

Photographs of children

family pictures that should stay in the family

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

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.

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?

WebP compresses without discarding data, but it cannot represent everything an HEIF file holds. What does not fit is discarded permanently, so converting the result back will not restore it. Keep the HEIF original if it is the only copy.

HEIF to WebP Converter — questions

How do I convert HEIF to WebP?

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

Is it safe to convert HEIF files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your HEIF file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential HEIF files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

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 images may run out of memory on a phone — those are better converted on a laptop.
