You can upload PNG, JPG, WebP, GIF, BMP, SVG, and AVIF as input. The output options are JPG, WebP, and PNG. That covers the most common conversions: PNG to JPG, JPG to WebP, WebP to PNG, GIF to JPG, SVG to PNG, and more.

Yes. No account, no signup, no credit card, no watermark on the output. The tool runs entirely in your browser so there is nothing to log in to and nothing to install.

No. All conversion happens inside your browser using the HTML5 Canvas API. Your image file never leaves your device. This also means there is no server-side file size limit and the tool works offline once the page has loaded.

WebP is the better choice for web use. It produces files 25 to 35 percent smaller than JPG at the same visual quality, and it is supported in all modern browsers. Use JPG when you need broad compatibility with older software or when sharing files outside of a browser context. Use PNG only when you need lossless quality or transparency.

For most images, 80 to 88 percent gives an excellent balance of file size and visual sharpness. Use 90 to 95 for product photos or portfolio images where quality is critical. Drop to 60 to 75 when file size matters more than sharpness, such as thumbnails or background images.

JPG does not support transparency. Any transparent pixels in the source image are filled with the background color you choose in the settings, which defaults to white. If keeping transparency is important, convert to WebP or PNG instead, both of which support alpha channels.

Yes. Before converting you can choose a resize mode: max width, max height, exact pixel dimensions, or a percentage scale. The resize and format conversion happen together in one step, so the downloaded file is already the right size.

Enter a target in KB and the tool runs a binary search across quality values to find the highest quality that still fits under your cap. If the image cannot reach that size even at the lowest quality, the tool tells you the smallest it could achieve so you know what to expect.
