Supported formats and how processing works
- Files you can open
- JPG, PNG and WebP, up to 25 MB each. iPhone HEIC/HEIF photos open only in the HEIC to JPG converter. PDFs open in the PDF to image tool.
- Files you can save
- JPG, PNG and WebP. WebP and AVIF output depend on your browser's encoder (in our tests, Chrome could not create AVIF). If your browser can't produce the format you picked, the tool tells you instead of saving a different format under the wrong file extension.
- Where the work happens
- In your browser, using its built-in canvas image encoder. The tools contain no upload step, so your image is not sent to our server. Our analytics (Google Analytics with Consent Mode) records usage numbers such as file size and format, never the image itself.
- What changes in the file
- The image is re-encoded, so camera metadata (EXIF, including GPS) is not carried over. JPG has no transparency, so transparent areas become white. PNG is lossless: to shrink one, reduce its dimensions or convert it to WebP.
