Image Tools

Convert images between PNG, JPG and WebP, resize to exact dimensions, and compress to shrink file size. Crop, rotate and flip photos, add a watermark, circle-crop avatars, build collages and memes, pick colors from an image, encode images to Base64, and generate app icons and favicons — all done in your browser with the Canvas API. Nothing is uploaded to a server.

Which image format, and which tool

Most image problems come down to format or size.

FormatCompressionTransparencyBest for
JPGLossyNoPhotos where small files matter
PNGLosslessYesScreenshots, logos, text and flat colour
WebPLossy or losslessYesWeb pages; usually noticeably smaller than an equivalent JPG
AVIFLossy or losslessYesWeb pages; often smaller again, but slower to encode
HEICLossy (HEVC)YesiPhone camera default; limited support outside Apple

To get a photo onto a website quickly, resize it to the width it actually displays at (often 1200–2000 px rather than a 4000 px original), then convert to WebP or compress it. Resizing is usually the bigger saving. How to compress images for the web covers the details.

For compatibility, use HEIC to JPG when a website or Windows app rejects iPhone photos. Use WebP to JPG or AVIF to JPG for images saved from the web that older software won't open. Converting PNG to JPG fills transparent areas with a solid background, so logos usually belong in PNG or WebP.

For editing, there are crop, rotate and flip tools, circle crop for profile pictures, plus watermark, meme and collage makers. The editing happens in a canvas inside your browser.
