Frequently asked questions
Which formats can I compress?
JPG (JPEG), PNG, WebP and AVIF. For HEIC photos from an iPhone, convert them to JPG first: the JPG is already much smaller.
Will my image lose quality?
At the Light level the change is barely visible, and PNG files stay lossless. Recommended and Strong save more space with a small loss of detail. Strong also reduces images larger than 2560 pixels on their longest side.
Is the location of my photos removed?
Yes. Metadata such as the GPS position and the camera model is not kept in the compressed image.
Is it free?
Yes, up to 10 files a day and 500 MB per file, without an account.
Why is my file the same size as before?
Because it was already well compressed, and a new pass would have made it bigger. We give you back the original in that case.

Same format, smaller file
A JPG stays a JPG, a PNG stays a PNG. JPG files are re-encoded with mozjpeg, WebP and AVIF at a tuned quality. PNG files are losslessly re-encoded at the Light level, and reduced to an optimized palette at the other levels, which suits screenshots and graphics very well.
Photos keep their orientation
Phone photos store their orientation in metadata. ConvertFly applies it before compressing, so the image is never turned on its side. Other metadata, including the GPS location, is removed, which also protects your privacy.
Never bigger than your original
An image that was already well compressed can come out larger after a new pass. In that case you get your original back, and the page tells you.
Need another format?
Converting can save even more than compressing: a PNG photo is usually far lighter as a JPG or a WebP. See the image converters below.
