HEIF to BMP Converter

Turn HEIF files into BMP in a couple of clicks. HEIF is the container standard HEIC is built on; BMP is an uncompressed raster bitmap. The conversion is lossless — every pixel, sample or byte in the source is preserved.

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 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:

Screenshots of private messages

conversations that included other people

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

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 BMP 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.

BMP stores pixels essentially raw, with little or no compression. A 1920×1080 BMP is around 6 MB regardless of what the picture contains, because every pixel takes the same space whether it is part of a gradient or a flat colour.

Where HEIF files come from
Newer cameras and some Android devices, alongside Apple's HEIC.
Where BMP is used
Legacy Windows software, some scientific and industrial imaging tools.

HEIF vs BMP

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

HEIF is stronger at

BMP is stronger at
Trivially simple to read and write. No compression artefacts whatsoever. Still readable by very old software.

Why convert HEIF to BMP?

People make this switch when they run into the limits of HEIF: you need to share the file with anyone. BMP is the better fit when a legacy application specifically requires it.

Be aware of the size trade-off: BMP is uncompressed, so expect the converted file to be considerably larger than the HEIF you started with.

HEIF limitations that prompt the switch
Support outside Apple and recent Android is limited. Confusing overlap with HEIC in practice.
What you give up
Enormous files. No standard support for transparency in most variants.

Does converting HEIF to BMP reduce quality?

Going from HEIF to BMP moves already-compressed data into a format that stores it exactly. Nothing is lost from this point on, but nothing is recovered either — the detail HEIF discarded when the file was first created is gone permanently. Expect a noticeably larger file for identical visual quality.

Good to know

HEIF to BMP Converter — questions

How do I convert HEIF to BMP?

Drop your HEIF file onto the area above, then press Convert. The BMP 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.

What should I know before converting HEIF to BMP?

Converting HEIF to BMP cannot restore detail that the original encoder already discarded. It preserves exactly what is there today — nothing more.

Does converting to BMP reduce quality?

No. BMP is a lossless format, so the conversion preserves exactly what is in your HEIF file. Note that it cannot recover detail that was already discarded when the HEIF was first created — a lossless container does not undo earlier compression.

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.
