Convert from AVIF
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.
Sharpen ImageApply a real unsharp mask with amount, radius and a noise threshold, and preview the result before you download it.
Circle CropCut a circle, an oval or a rounded square out of any photo and download it as a PNG with a genuinely transparent background.
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.
Image MetadataSee the camera, the exposure, the date and the GPS location stored inside a photo. It is read in this tab, never uploaded.
Remove Image MetadataStrip the GPS location, the camera details and the author's name out of a photo before you post it, without touching a single pixel.
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.
Transparent BackgroundPick the background colour and everything close to it turns transparent: green screens, white backdrops, scans and flat logos, in a blink.
Split ImageCut a picture into a grid, into rows or columns, or along your own cut lines. There is an Instagram carousel preset for 3, 6 or 9 slides.
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.
Photo Collage MakerPut two to twenty photos on one canvas, as a grid, a mosaic, a filmstrip or placed by hand, and download the result as a single picture.
Photo EditorLayers, text, shapes, a brush and colour adjustments on one canvas. Everything runs in this tab and nothing is uploaded.What AVIF buys you
AVIF uses the AV1 video codec to compress still pictures, and it is better at it than anything before: typically 20 to 30 per cent smaller than WEBP and half the size of JPEG at the same visual quality, with transparency, wide colour and high dynamic range included. On photographs with smooth gradients, such as skies, skin and shadows, the difference is not subtle, because the blocking that JPEG produces at low bitrates does not appear.
The cost of that compression
Encoding AVIF is slow, several times slower than JPEG or WEBP for the same picture, which is why it is a format for things you publish rather than things you process in bulk. Support outside browsers still lags: many desktop tools, older phones and most print workflows do not read it. As with HEIC, the sensible pattern is to publish AVIF and keep something ordinary for everything else. The conversions in both directions are here for that.
AVIF, HEIC and the file that lies about itself
AVIF and HEIC are close relatives, both pictures inside an ISO base media container, and files are routinely mislabelled: a download named .heic that is really AVIF is common enough that the tools here identify pictures by their signature rather than by the extension. That is why an image opens correctly even when its name is wrong, and why a file that really is something else is rejected instead of half-converted.
AVIF for a website: what to convert and what to keep
AVIF pays off on photographs that are downloaded many times: a hero image, a product gallery, a blog illustration. Convert those from the original JPEG or PNG, not from a WEBP that was already compressed once, and keep the quality around 60 to 70, where AVIF still looks cleaner than a JPEG at 85 for half the bytes. Encoding is slow, so a batch of fifty large photos is a coffee break, not a click. Keep screenshots and icons in PNG or lossless WEBP, where AVIF's advantage is small. And keep the originals: when a print shop or an old laptop asks for a JPEG, convert from the master again rather than from the AVIF.
Frequently asked questions
Is AVIF better than WEBP?
Smaller at the same quality, typically by 20 to 30 per cent, and better on smooth gradients. It is slower to encode and still less widely supported outside browsers, so WEBP remains the safer choice for anything that leaves the web.
Which browsers and apps open AVIF?
Every current browser does: Chrome, Firefox, Safari from version 16 and Edge. Desktop viewers are catching up, Windows needs the AV1 extension, and most print and office software does not read it yet. When you need a JPG or PNG back, open the AVIF in Photo Editor here and export it.
Why does my AVIF conversion take so long?
AV1 compression searches much harder for savings than JPEG does, and the encoder runs in your browser rather than on a server. The speed setting trades a few per cent of size for several times faster encoding; raise it for a batch.
