What makes PNG different
PNG stores every pixel without compression loss. Unlike JPG, it supports full transparency through an alpha channel, making it the standard for graphics that need to sit on different colored backgrounds. PNG is also the preferred format for screenshots, interface elements, and any image where text or sharp edges must remain pixel-perfect.
Should you convert your JPG to PNG?
Converting a JPG to PNG does not recover the quality lost during original JPG compression — that information is gone permanently. The only reasons to convert JPG to PNG are: you need to add transparency to the image using an editor, you need the exact pixel data for further editing without additional generational loss, or a tool or platform explicitly requires PNG. Do not convert just to 'improve quality' — it will not help.

Upload your JPG image to the JPG to PNG tool. The conversion preserves all existing pixel data at full quality and wraps it in a lossless PNG container. Download the result. The file will be noticeably larger than the original JPG, which is expected — PNG files for photographic content are typically 3–5× the size of their JPG equivalents.
Use cases where JPG to PNG makes sense
Editing workflow: if you plan to edit an image multiple times, saving as PNG between edits avoids accumulating JPG compression artifacts. Transparency editing: open the PNG in an editor like GIMP or Photoshop, use the eraser or magic wand to create transparency, and save — the alpha channel is now available. Print preparation: some professional print workflows require PNG or TIFF instead of JPG for reliable color reproduction.
PNG file size considerations
PNG files for photographs are significantly larger than JPG files. For web delivery, this is usually a disadvantage. If you have edited your image in PNG and need to publish it online, convert back to JPG or WebP at the end of your workflow to recover the size efficiency. Think of PNG as the working format and JPG/WebP as the delivery format for photographic content.
