Convert an image to the format you need
Drop the image and pick JPG, PNG or WebP. Refentra converts it on your device and tells you what changes, like a white background instead of transparency.

Questions
Can I just rename the file extension?
No. Renaming changes the name, not the file. The site still sees the original format.
Which format should I choose?
JPG for photos, PNG for screenshots and graphics with sharp edges or transparency, WebP only if the destination lists it.
Does converting lower the quality?
Saving as JPG or WebP compresses slightly; PNG keeps every pixel but is larger.
