Image Converters

Convert between JPG, PNG, WebP, AVIF, HEIC, SVG, BMP, GIF, TIFF, and ICO. The conversions use the HTML Canvas API and, for HEIC files, the heic2any library. Everything runs in your browser. Your images stay on your device.

Picking the right format

JPG is the default for photos. Lossy compression, small files, works everywhere. PNG is lossless and supports transparency, so it is the go to for screenshots, UI assets, and anything where you need exact pixel reproduction. WebP beats both on compression. Same visual quality as JPG at 25 to 35% smaller file sizes, and it handles transparency too. Browser support is universal now.

HEIC is what iPhones shoot by default since iOS 11. Great compression but Windows and most web forms still do not accept it, which is why HEIC to JPG is one of the most common conversions here. SVG is vector based, so it scales to any size without pixelation. Good for logos and icons, but you need to rasterize it to PNG or JPG before you can use it in places that only accept bitmap images. AVIF is the newest format and compresses even better than WebP, though tooling support is still catching up.

What people use the most

• HEIC to JPG to share iPhone photos with people on Windows or Android
• PNG to WebP for cutting image sizes on websites, usually 50 to 70% savings
• JPG to PNG when you need lossless quality or plan to edit the image further
• SVG to PNG to turn vector graphics into bitmaps for social media or docs
• WebP to JPG because you saved an image from a website and nothing can open it
• JPG to WebP for web performance optimization, easy Lighthouse win

How it works under the hood

For most image formats, the converter draws your image onto an HTML Canvas element and re exports it in the target format. The Canvas API handles JPG, PNG, and WebP natively. For HEIC decoding, we load the heic2any library on demand so it does not slow down the initial page load. SVG rendering goes through the same Canvas pipeline. The 100 MB file size limit is a practical cap since large images eat browser memory fast, especially on phones.

One thing worth noting: lossy to lossy conversions (like JPG to WebP) do re encode the image, so there is a theoretical quality loss. At the default High quality setting it is invisible in practice, but if you are going back and forth between formats repeatedly, quality will degrade over time. You can adjust the quality level in the Conversion Settings panel on each converter page. Convert once and keep the result.
