- 2

Convert and download
Press Convert image. The result appears with its real size and dimensions, ready to download.
Which format should you pick?
- JPG — photographs, and anywhere maximum compatibility matters. No transparency.
- PNG — screenshots, logos, line art and anything needing a transparent background. Lossless, so files are larger.
- WebP — a good default for the web. Typically 25–35% smaller than JPG at comparable quality, and it supports transparency.
- AVIF — the smallest of the four at a given quality, but the slowest to encode and the least widely supported by desktop software.
What happens to the original
Nothing. Your file is read into memory, decoded, re-encoded and handed back to you as a download. The original on your disk is untouched, and no copy is kept anywhere.
Because the output is re-encoded from decoded pixels, camera metadata such as EXIF and GPS coordinates is not carried across. That is a deliberate privacy default.
Frequently asked questions
- Are my images uploaded to a server?
- No. The conversion runs in your browser using WebAssembly and canvas APIs, so the image data never leaves your device. There is no upload endpoint in this application at all — you can watch the network tab while you convert.
- Is there a file size or daily limit?
- No. There is no quota, because there is no server doing the work — the limit is your device's memory. Very large images may take a few seconds on an older phone.
- Will there be a watermark?
- No. The output is exactly the image you converted, with no marks added.
- Do I need an account?
- No. There is no signup, no email, and no login anywhere in this tool.
- Which formats can I convert between?
- JPG, PNG, WebP and AVIF, in any combination. The tool also reads formats your browser can decode, such as GIF and BMP, and converts them into one of those four.
