Créer un GIF en ligne

What Créer un GIF does

A GIF maker puts several still images into one animated GIF that shows them one after another, like a slideshow or a flip book. It is used for simple animations, before-and-after comparisons, product photo sequences and memes.

Every image is scaled to the GIF size you choose, either fitted inside the frame or cropped to fill it, and drawn on the background color. Each frame is then reduced to a palette of up to 256 colors and written to the GIF with the frame duration you set.

Comment utiliser Créer un GIF

1. Déposez vos images et placez-les dans l'ordre souhaité.
2. Choisissez la taille, le rythme ou la mise en page.
3. Cliquez sur Créer.
4. Téléchargez le fichier final.

When to use Créer un GIF

• Combine several product photos into one animated GIF that shows every angle in a single image slot.
• Make a before-and-after GIF from two photos of a room, a haircut or an edited picture.
• Animate a sequence of drawings or stop-motion photos into a short looping animation.
• Turn slides or screenshots into a simple animated walkthrough for a chat message or a README file.

Settings explained

Frame duration

How long each image stays on screen, in milliseconds, from 20 to 10,000. The default of 500 shows two images per second; use 1000 to 2000 for slideshows and 50 to 100 for smooth animation.

Width

The width of the GIF in pixels, from 16 to 2000, with 600 as the default. The height is taken from the aspect ratio of the first image in the list.

Fit

Fit inside shows each whole image and fills the empty space with the background color. Fill and crop covers the whole frame and cuts off the edges of images that have a different shape.

Background color

Fills the space around images that do not cover the frame, and any transparent areas. The default is white. The finished GIF has no transparent pixels.

Loop forever

When it is on, which is the default, the animation repeats endlessly. Turn it off to play the images once and stop on the last one.

Format comparison

Qu'est-ce que le format PNG ?

PNG (Portable Network Graphics) est un format d'image créé par W3C en 1996. Il utilise une compression sans perte et gère la transparence. Les fichiers portent l'extension .png.

PNG was created in the mid-1990s as a free replacement for GIF, whose compression method was covered by patents at the time. It applies a filtering step and then compresses pixels with the DEFLATE algorithm, so every pixel is kept exactly. It supports full color, grayscale, palette images and a full alpha channel for smooth transparency.

PNG is the right choice for screenshots, logos, icons, diagrams, user interface graphics and any image with sharp edges, text or flat colors. It is also a safe format for images that need transparent backgrounds or will be edited again.

Because PNG is lossless, photos saved as PNG are often several times larger than the same photo saved as JPG or WebP. PNG has no lossy mode, and a standard PNG file cannot store animation.

PNG opens in every modern web browser, on Windows, macOS, Linux, Android and iOS, and in practically all image viewers, image editors, office suites and design tools. It is one of the most widely supported image formats.

Qu'est-ce que le format JPG ?

JPG (Joint Photographic Experts Group) est un format d'image créé par JPEG en 1992. Il utilise une compression avec perte et ne gère pas la transparence. Les fichiers portent l'extension .jpg ou .jpeg.

JPG, also written JPEG, is named after the Joint Photographic Experts Group, which wrote the standard. It splits an image into small blocks, transforms each block with a discrete cosine transform and discards the fine detail that the eye notices least. A quality setting controls how much detail is removed and therefore the file size.

JPG is the standard choice for photographs and other images with smooth color gradients, such as camera pictures, product photos and images for email or social media. It gives small files with good visual quality at moderate settings.

JPG does not support transparency or animation. Each time a JPG is edited and saved again, it loses a little more quality. Text, line art and sharp edges can show visible blocks or halos at low quality settings.

JPG is supported everywhere: in all web browsers, on all desktop and mobile operating systems, and on cameras, phones and printers. All image editors and office programs open it. It is the most compatible format for sharing photos.

Qu'est-ce que le format WEBP ?

WEBP (WebP) est un format d'image créé par Google en 2010. Il prend en charge la compression avec et sans perte, gère la transparence et peut contenir des animations. Les fichiers portent l'extension .webp.

WebP was developed by Google to make images on the web smaller. Its lossy mode is based on the VP8 video codec, and it also has a separate lossless mode. Both modes can include an alpha channel for transparency. The format also supports animation, so it can replace JPG, PNG and GIF in many cases.

WebP is a good choice for images on websites and in apps, where smaller files load faster. It works for photos, graphics with transparency and short animations, often at a smaller size than JPG, PNG or GIF.

Some older software, image editors, print services and upload forms still do not accept WebP. Lossy WebP always reduces color resolution, which can blur fine colored detail. At very high quality settings, the size benefit over JPG can be small.

All current major browsers display WebP, including Chrome, Edge, Firefox and Safari on recent versions of macOS and iOS. Windows, macOS, Android and most modern image editors open it, but some older desktop programs do not.

Qu'est-ce que le format HEIC ?

HEIC (High Efficiency Image File Format (HEIF)) est un format d'image créé par MPEG en 2015. Il utilise une compression avec perte et gère la transparence. Les fichiers portent l'extension .heic ou .heif.

HEIC is an image stored in the HEIF container and compressed with the HEVC (H.265) video codec. Apple made it the default photo format on iPhones starting with iOS 11. One file can hold several images, depth maps and other data, and it keeps quality similar to JPG at a noticeably smaller size.

HEIC is good for storing many photos on a phone, because it saves space while keeping good quality. It can also keep extra information in the same file, such as the depth data used for portrait effects.

Most websites and many Windows and Android apps cannot open HEIC files directly. The HEVC codec is covered by patents, which limits free support. When you share photos outside Apple devices, converting to JPG is often necessary.

HEIC opens natively on iPhone, iPad and Mac. Recent Windows versions can open it with the HEIF and HEVC extensions from the Microsoft Store, and many recent Android phones can read it. Most browsers other than Safari cannot display it.

Pourquoi utiliser l'outil Créer un GIF de FansBond

La plupart des convertisseurs en ligne envoient vos fichiers sur leurs serveurs. L'outil Créer un GIF de FansBond fait tout le travail dans votre navigateur, grâce à WebAssembly et aux API modernes des navigateurs. Vos fichiers restent sur votre appareil, ce qui est plus sûr pour vos photos privées, vos contrats et vos projets non publiés, et c'est souvent plus rapide puisqu'il n'y a rien à envoyer ni à télécharger.

Pas de file d'attente, pas de filigrane, pas de compte. Une fois la page chargée, l'outil continue de fonctionner même avec une connexion lente.

Tips for the best result

• Use the up and down arrows in the file list to set the order. The first image also sets the shape of the GIF.
• Use images with the same size and shape, so every frame lines up and nothing is cropped or padded.
• Keep the width small, such as 480 or 600 pixels, when the GIF is meant for chats or email, because every frame adds to the file size.
• Photos with smooth gradients can look banded in a GIF. Graphics, drawings and screenshots with flat colors give the cleanest result.

How Créer un GIF works in your browser

GIF files can only hold 256 colors per frame, so the tool analyzes each frame, builds the best palette for it and maps every pixel to that palette. Video frames are first extracted with a WebAssembly build of FFmpeg.

The encoder and the GIF decoder run in JavaScript and WebAssembly inside your browser tab. Frame timing, looping and size are written directly into the GIF file, so the result plays the same way in every browser and chat app.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Créer un GIF works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
