PNG — lossless, supports transparency
Convert between common image formats — JPG, PNG, WebP, GIF. Batch a folder at once. Conversion runs entirely in your browser using native canvas and codec APIs.
There is no universally best format. Each one was designed for a different content type, and the right pick depends almost entirely on what is in the image.
JPG — for photographs and any content with smooth color gradations. Lossy compression that looks invisible on photo content at 85+ quality. Bad for sharp edges, text, and transparent backgrounds (which JPG does not support at all).
PNG — for screenshots, logos, illustrations, anything with sharp edges or text, and any case where transparency matters. Lossless — every pixel preserved exactly. Larger files than JPG for photo content.
WebP — modern format from Google, supported in every browser since 2020. Has both lossy and lossless modes. Lossy WebP is typically 25-35% smaller than equivalent JPG. Lossless WebP is typically 25-30% smaller than equivalent PNG. Supports transparency. The right default for web delivery in 2026.
GIF — legacy format that still has one relevant use case (short animations). For static images, anything else is better. The 256-color limitation makes GIFs of photographs look posterized.
Conversion is not free
The decoding and re-encoding both happen via canvas and the browser's built-in codec implementations. No server-side processing means no upload of your image, regardless of what is in it.
For related operations: compress for size reduction within a single format, resize for changing pixel dimensions, crop for changing aspect ratio.
