Format
Convert a PNG to JPG.
Some forms only accept JPEG files. The checker below is already set to require JPG. Add your PNG, check it, and Filnixa writes a JPG copy on your device.
No account. Your file is read on your device and never sent to us.
JPG is preselected as the required format. Add a size limit too if the form has one.
Why the format matters
A form that only accepts JPG will refuse a PNG even when the file is small and the pixel size is fine. The rule is about how the picture is stored, not how big it is.
PNG keeps every pixel exactly and supports transparency, which suits logos and screenshots. JPG throws away detail people do not notice, which makes photographs far smaller.
How Filnixa converts
Your PNG is decoded in the browser and redrawn as a JPG. Transparent areas are filled with white first, because JPG has no way to store them.
If you also set a maximum file size, the conversion and the compression happen in one step, and the finished JPG is checked against both rules.
