PNG is a lossless format, making it better for images that need to be edited or re-saved multiple times without quality degradation. PNG also supports transparency, making it ideal for logos, icons, screenshots with transparent backgrounds, and graphics used in design projects.
Converting JPG to PNG does not improve quality — any quality loss that occurred when the JPG was originally compressed cannot be recovered. However, PNG preserves the current quality without any further degradation. Future edits and re-saves as PNG will not reduce quality further.
Yes. PNG is a lossless format and generally produces larger files than JPG for the same image. A JPG photo converted to PNG can be 3–5x larger. This is expected and is the trade-off for lossless quality and transparency support.
Converting a JPG to PNG does not automatically add transparency since JPG has no transparency data to carry over. The PNG will have a solid background. To add transparency, you would need to use an image editor like Photoshop or GIMP to remove the background after conversion.
Yes. Upload multiple JPG files simultaneously. They are all converted to PNG in parallel and can be downloaded individually or as a ZIP archive.
