GIF to WebP Converter

Turn GIF files into WebP in a couple of clicks. GIF is a 256-colour animated format, still ubiquitous; 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
Add your GIF 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
Adjust the settings if you want to
The defaults suit most people. Open Advanced to control quality and metadata removal.
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 GIF 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 GIF 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:

Medical scans and photographs

X-rays, results, images of a condition

Photographs of children

family pictures that should stay in the family

Passport and visa photos

biometric-grade images of your face

Screenshots of private messages

conversations that included other people

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.

GIF and WebP explained

GIF is a 1987 format limited to a 256-colour palette per frame, with support for simple animation and one fully transparent colour. Its longevity is cultural rather than technical — nothing about it is efficient by modern standards.

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 GIF files come from: Reaction images, simple UI animations, and screen recordings shared in chat.
Where WebP is used: Modern websites, and increasingly the default export from web-focused design tools.

GIF vs WebP

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

GIF compared with WebP
Property	Source	Target
Compression	Lossless	Lossy or lossless
Transparency	Yes	Yes
Animation	Yes	Yes
Colour limit	256 per frame	Full colour
Introduced	1987	2010
Browser support	Universally supported.	All modern browsers. Some older desktop apps can't open it.

GIF is stronger at: Animation plays anywhere without a video player. Universally supported, including in email and old forums. Lossless within its 256-colour limit.
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 GIF to WebP?

People make this switch when they run into the limits of GIF: the content is photographic, longer than a few seconds, or would be better as MP4 or WebM. WebP is the better fit when you are publishing images on a website and want smaller files without a visible quality drop.

GIF limitations that prompt the switch: 256 colours per frame, so photographs and gradients look banded. Enormous files compared with video — often 5–10× an equivalent MP4. Transparency is binary: a pixel is either fully opaque or fully transparent, producing jagged edges.
What you give up: Desktop applications and older software often cannot open it. Some photo printing services and older phones reject it.

Does converting GIF to WebP reduce quality?

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

A GIF is not a video. It is a sequence of full images with no interframe compression, which is exactly why it is so large.

Measured, not estimated

What converting GIF to WEBP actually costs

It depends entirely on the content: across the samples the WEBP ranged from 4.6× smaller to 1.4× larger, with a middle case 2.9× smaller.

Nothing came through untouched. Similarity against the input file ranged down to 0.985, where 1.000 would mean no visible change at all.

Each row is one sample chosen to isolate a property these formats treat differently.
Sample	GIF in	WEBP out	Change	Similarity
Smooth gradientContinuous tone with no detail — the easiest thing to compress, and where banding shows first.	32.5 KB	8.6 KB	−73%	0.985
Hard-edged text and UIHigh-contrast edges. This is where JPEG's ringing artefacts appear and where PNG wins.	34.3 KB	48.2 KB	+40%	0.998
Film-like noiseRandom detail. Incompressible by design — the worst case for every lossy codec.	318 KB	201 KB	−37%	0.992
Flat colour blocksLarge areas of one colour — a logo or a chart. Lossless formats should crush this.	4.4 KB	1.5 KB	−66%	0.998
Soft alpha edgeA transparent gradient. JPEG cannot store it at all, which is the single most common reason a conversion surprises someone.	20.3 KB	4.4 KB	−78%	1.000

Produced by a stand-in encoder. Your browser's own encoder has no equivalent outside a browser, so this was measured with the same codec at the same quality from a different implementation. Expect the shape of the answer to hold and the exact bytes to differ.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size.

GIF to WebP Converter — questions

How do I convert GIF to WebP?

Drop your GIF 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 GIF 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 GIF 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 GIF 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 GIF to WebP?

Animated GIFs produce a still image from the first frame. Convert to MP4 or WebM to keep the motion.

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.
