PNG, JPG, WebP supported
The best target format depends on what the image needs to keep: transparency, broad compatibility, or the smallest practical web file. These are the most common conversion patterns for this tool.
Best for: Blog posts, landing pages, and product photos where file size matters more than editability.
What changes: Usually the safest first move when you want smaller web images without changing dimensions or transparency behavior.
Watch for: Very high quality settings often erase the size win. Start around 80 to 90 and compare visually.
Best for: UI graphics, illustrations, and product cutouts that need transparency but still need better delivery size.
What changes: Keeps transparent backgrounds while producing smaller files than a typical PNG export.
Watch for: Flat graphics with text should be reviewed closely. Some assets are still better left as PNG for pixel-perfect edges.
Best for: Email images, ad creatives, or marketplaces that only accept JPG uploads.
What changes: Flattens transparency onto a solid background and gives you the widest compatibility.
Watch for: Pick the background color before converting. Transparent edges will be replaced permanently.
Use this converter to switch between PNG, JPG, and WebP based on quality, transparency, and delivery performance requirements. All conversion happens in your browser — no files are uploaded to a server.
ImageLab processes files locally in your browser. Files are not uploaded to our servers, which is useful for sensitive screenshots, internal product images, and personal photos.
At quality 80–92%, WebP produces images that are visually indistinguishable from the original for most photographic content. The compression algorithm is more efficient than JPG, so the same visual quality is achieved at a smaller file size. If you need perfectly lossless output, use PNG.
JPG does not support transparency. When converting a transparent PNG or WebP to JPG, the transparent pixels are filled with a solid background color. Use the background color picker to choose what color replaces the transparency. White is the default.
Yes. Drop multiple files onto the upload area and all of them will be converted using the same settings. Download them individually or as a single ZIP archive.
There is no hard limit — the tool runs in your browser and is constrained only by your device's available memory. Very large images (above 20–30 megapixels) may take a few seconds to process.
