JPEG to PNG Transformation FAQ
How do I convert JPEG to PNG without losing image quality?
+
Upload your JPEG file, then our converter applies format-aware quality optimization for PNG output. For lossless formats (PNG, TIFF, BMP) we preserve every pixel; for lossy formats (JPG, WebP) you can tune the quality factor before download. JPEG is the same standard as JPG and JFIF — the four-letter extension is the original, and the three-letter one exists only because of the DOS 8.3 filename limit.
Does JPEG to PNG conversion preserve transparency?
+
Transparency survives when going to PNG, WebP, TIFF, GIF or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of PNG.
What about EXIF metadata when converting JPEG to PNG?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the PNG. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.
Can I batch-convert hundreds of JPEG files to PNG at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What resolution and dimensions will my PNG file have?
+
Default behaviour is 1:1 — your PNG output has the same pixel dimensions as the source JPEG. If you need to resize as part of the conversion, use the /resize-image/ tool after conversion, or chain it with the /image-resize/ utility.
How small can the PNG file get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source JPEG with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Are my JPEG files private during conversion?
+
Yes. Uploaded JPEG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why is my converted PNG file bigger / smaller than I expected?
+
A JPEG file with strong compression (e.g. heavily lossy JPG) often grows when re-encoded to a lossless PNG (PNG, TIFF), and a high-bitrate lossless JPEG often shrinks dramatically when going to JPG/WebP. The ratio depends on image content (photos compress differently from line art).
Can I use the converted PNG file commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source JPEG). We add no watermark, no metadata stamp, and claim no licence over the output.
