Convert JPG to PNG - Lossless Quality

PNG is lossless and supports transparency, while JPG is lossy and cannot. Converting is useful when
you want to edit the image repeatedly, add transparency in an editor, or stop further quality loss
from re-saving as JPG.

It will not recover detail the JPG already lost, but it will not lose any more. Converting freezes
the current quality and prevents the gradual degradation that repeated JPG saving causes.

PNG uses lossless compression, so a photo saved as PNG is typically 2 to 5 times larger than the
JPG. That is expected. Choose PNG when quality and editing matter more than file size.

No. A JPG has no transparency to begin with, so the PNG keeps the same solid background. You can
later remove or replace that background in an image editor.

and keeps private images private.

Yes. They are the same format with different extensions, and the tool accepts both.

Yes. The width and height in pixels stay identical. Only the format and compression change.

Use PNG for logos, screenshots, diagrams, images with sharp text, and anything you plan to edit
again. Use JPG for photographs you want to keep small.

Yes. It runs in any modern browser on Android, iPhone, iPad, Windows, Mac, and Linux, with no app
to install.

The tool converts one image at a time so you can preview each result. Use Convert Another to run
through several files in a row.
