Moving a JPG into a PNG container does not recover detail that lossy compression already removed — that data is gone. What you do gain is a lossless wrapper: from this point forward the file can be edited, resaved, and composited as many times as needed without accumulating any further quality loss.
The most common reasons to make this switch: you need to place the image in a design tool that treats PNG as its working format, you are stripping the background and need alpha-channel support, or you simply want a stable archive copy that won't degrade through repeated exports.
It is worth being direct: converting JPG to PNG does not sharpen the image, remove JPEG artifacts, or restore color accuracy. The compression damage baked into the JPG is faithfully captured in the PNG — it is just frozen there rather than compounded. What you get is a guarantee that no further quality loss occurs from this point on.
For photographic content, expect the PNG to be noticeably larger than the source JPG. Photo data compresses poorly in lossless format; that size increase is normal and expected.
Design and compositing workflows often call for PNG. Figma, Photoshop, and Affinity Photo treat PNG as a natural working format — it layers cleanly, maintains crisp edges after transformations, and supports the alpha channel you need when removing or replacing a background. If your JPG is destined for any of these uses, converting to PNG first gives you the most flexible source material to work from.
Similarly, if you are sending an image through a pipeline that saves intermediate copies, PNG prevents each save from adding another round of lossy compression.
JPG has no alpha channel, so the PNG output will have a fully opaque background — no hidden transparency is introduced by the conversion. Every pixel that was visible in the JPG is present in the PNG at the same color value. If you later want a transparent background on that PNG, that is a separate editing step (background removal) performed after conversion.
No. JPEG artifacts already embedded in the source are preserved in the PNG. You get lossless storage from this point forward, but any detail lost during the original JPEG encoding cannot be recovered.
PNG is lossless — it stores every pixel value without discarding data. Photos contain complex gradients that compress poorly without loss, so much larger file sizes relative to JPG are normal and expected.
Yes. Upload up to 200 JPG files per run, each up to 80 MB. Multiple outputs are packaged into a single ZIP for download.
EXIF metadata is stripped by default for privacy. If you need to keep shooting data, copyright tags, or camera info in the output PNG, enable the Keep metadata (EXIF) checkbox before starting.
PNG compression is lossless — adjusting the compression level changes file size only slightly and never affects visual quality. You can stack the Compress tool in the same run if you need to reduce PNG file size further.
