Convert Images Between Any Format
Convert between PNG, JPG, WebP, HEIC, SVG, GIF, BMP, and ICO formats instantly. Drop a file, pick your output format, adjust quality if needed, and download the result. All processing happens in your browser using the Canvas API. No files are uploaded, no accounts required, no limits on file size or batch count.
How to Use
- Drop an image file onto the converter or click to browse. You can also paste from clipboard with Ctrl+V / Cmd+V
- The source format is auto-detected. Select your target format from the output dropdown
- Optionally adjust the quality slider (for JPG and WebP) or expand the resize controls
- Preview the result side by side with the original, including file size comparison
- Download the converted file, or use Download All as ZIP for batch conversions
How Image Format Conversion Works
Every raster image is a grid of pixels, each storing color values (typically red, green, blue, plus an optional alpha channel for transparency). Image formats differ in how they compress this pixel data for storage.
PNG uses lossless compression. Every pixel is preserved exactly, which makes it ideal for screenshots, text, and graphics with sharp edges. The tradeoff is larger file sizes for photographs.
JPEG uses lossy compression tuned for photographs. It exploits the fact that human eyes are less sensitive to small color variations than to brightness changes, discarding information that is mostly imperceptible. A quality setting of 85% typically produces images visually indistinguishable from the original at 5-10x smaller file sizes.
WebP, developed by Google, supports both lossy and lossless compression, plus transparency. For lossy compression it produces files 25-35% smaller than JPEG at the same visual quality. For lossless, it beats PNG by around 26%. Browser support reached 97% globally in 2024.
HEIC (High Efficiency Image Coding) is based on the HEVC/H.265 video codec. iPhones use it by default because it produces files roughly 50% smaller than JPEG. The tradeoff is limited software support outside the Apple ecosystem. This tool uses a WebAssembly decoder to convert HEIC without any server involvement.
SVG is a vector format defined in XML. Converting SVG to a raster format (PNG, JPG, WebP) renders it at a specific pixel resolution. This is a one-way operation because the vector information is lost during rasterization.
This tool uses the HTML Canvas API to perform all conversions. The image is drawn onto a canvas element, then exported in the target format using canvas.toBlob(). For resize operations, the canvas dimensions are set before drawing, and high-quality bicubic interpolation smooths the result.
