Convert from GIF

GIF to PDFPut GIF images into a PDF in your browser, with animated files reduced to their first frame and transparency handled the way you ask.Compress ImageShrink JPG, PNG, WebP, AVIF and GIF files in your browser: pick a level that keeps the resolution, or, for all but GIF, a target size in KB or MB.Resize ImageChange the pixel dimensions of a photo by exact size, percentage or a ready preset, without leaving your browser.Bulk ResizeBring a whole folder of photos to one size in a single pass. Up to 500 files, one ZIP at the end.Crop ImageDrag a frame over your photo or type exact pixels, then download just the part you kept. Nothing leaves your browser.Rotate ImageTurn a photo 90, 180 or 270 degrees, or straighten it by any angle down to a tenth of a degree, right in your browser.Flip ImageMirror a photo horizontally, vertically or both at once. Same size, same format, nothing uploaded anywhere.Image to Base64Turn an image into a Base64 data URI for CSS, HTML or JSON, or paste a Base64 string and get the image file back.Convert to WebPTurn JPG, PNG, GIF, AVIF, BMP and HEIC images into WebP and cut a quarter to a third of their weight, without uploading anything.Convert to AVIFRe-encode JPG, PNG, WebP, GIF, BMP and HEIC as AVIF, the smallest of the widely supported web formats, with transparency intact.Image to TextRead the printed text out of a photo, screenshot or scan and download it as a .txt file, or as JSON with the position and confidence of every block.Add Text to PhotoPut a caption on any photo in your browser. Pick a size, colour, outline, shadow, colour plate or a curve, then download the result.Add WatermarkStamp a text or logo watermark on up to 100 photos at once, in one of nine positions or as a tiled pattern, with your own opacity, angle and size.Meme GeneratorTurn your own picture into a classic meme: top and bottom captions in heavy white letters with a black outline, or on white boxes.YouTube Thumbnail MakerCrop any photo to an exact preset or custom size, add a title in one of five styles, and get a JPG under 2 MB, small enough for YouTube from a phone.Photo EditorLayers, text, shapes, a brush and colour adjustments on one canvas. Everything runs in this tab and nothing is uploaded.GIF to MP4Turn an animated GIF into an H.264 MP4 video that keeps its frame rate and timing, right in your browser, with no upload and no watermark.

What GIF still does well

One thing: it plays a short silent animation in absolutely anything, including places that will not accept a video file: chat apps, forums, email clients, ancient content systems. That is a real advantage, and it is the only one left. For static pictures GIF is worse than PNG in every respect, and for animation it is worse than video in every respect except compatibility.

Why GIFs are so large

Because each frame is stored as a palette image with at most 256 colours and compression that predates the web. A five-second clip that would be a 400 KB MP4 is routinely 8 MB as a GIF, and the colour banding is visible on any photographic content. If the destination accepts video, converting a GIF to MP4 or WEBM cuts the size by an order of magnitude and looks better; if it does not, the levers are fewer frames, fewer colours and smaller dimensions.

Making a GIF that is worth sending

Keep it short, under five seconds, crop tightly, drop the frame rate to 12 or 15, and reduce dimensions before anything else: halving the width quarters the pixels. Photographic footage will always band; graphics and screen recordings, which have flat colour to begin with, are what the format was built for and still look fine.

GIF to MP4 for Twitter, Telegram and the web

The fastest way to make a GIF smaller is to stop it being a GIF. The same five-second clip is a tenth of the size as an MP4, plays smoother, and every social network converts uploaded GIFs to video anyway: Twitter and Telegram both store them as MP4 and merely label them GIF. GIF to MP4 does the conversion in the browser, can repeat the animation three times or up to a minute's worth, since an MP4 has no loop flag of its own, and can add a silent audio track for the platforms that reject a video without one. When the destination really needs a GIF, an email client or an old forum, go the other way with Video to GIF and keep it short: under five seconds, 12 to 15 frames per second and no wider than it has to be.

Frequently asked questions

How do I make a GIF smaller?

Fewer pixels first: halving the width cuts the file by three quarters. Then fewer frames, 12 to 15 per second, and fewer colours. If the destination accepts video, GIF to MP4 shrinks it by an order of magnitude with better quality.

Why does my GIF look grainy?

GIF stores at most 256 colours per frame, so photographic footage gets dithered into visible grain and banding. Graphics and screen recordings with flat colours look fine; for video content, MP4 or WEBP animation avoids the problem entirely.

Can a GIF have sound?

No, the format has no audio track at all. A clip that needs sound has to be a video; GIF to MP4 can add a silent track so that platforms treat the result as a normal video file.
