What to know before you convert
- Transparency is lost: transparent areas become white. Use PNG to WebP if you need both small and transparent.
- JPG is lossy. Light or Balanced for photos; avoid Strong for screenshots with text.
- Graphics with flat colours and sharp edges look worse as JPG and often aren't much smaller; keep them as PNG or WebP.

Nothing is uploaded
ConvertX converts on the device. There is no server, no account and no file size or count limit beyond your storage. Location and camera details are removed from every output unless you turn on "Keep photo details" (JPG can carry them).
Frequently asked questions
How much smaller will the JPG be?
For photographic PNGs, 80–95 % at Balanced quality. Flat graphics save far less.
What happens to the transparent background?
It becomes white. JPG has no alpha channel.
Which quality should I pick?
Balanced for most photos. Light if the picture will be printed or edited. The compressor page lets you preview the size on one file first.
