JPG to JPEG Conversion FAQ
How do I convert JPG to JPEG without losing image quality?
+
It helps to know what each side actually is: JPG stores 8-bit RGB through a lossy DCT with 4:2:0 chroma subsampling by default, so fine red text and hard edges are the first things to soften, while JPEG is the same codec as JPG under a longer extension — identical DCT pipeline, identical quantisation tables, nothing about the pixels changes with the filename. Upload your JPG file and our converter applies format-aware quality optimization for JPEG output — for lossless targets (PNG, TIFF, BMP, PSD) every pixel is preserved; for lossy targets (JPG, WebP, GIF) you can tune the quality factor before download.
Does JPG to JPEG conversion preserve transparency?
+
Transparency survives when going to PNG, WebP, TIFF, GIF, ICO, PSD or SVG. Converting to JPG / JPEG / JFIF flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of JPEG.
What about EXIF metadata when converting JPG to JPEG?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the JPEG. 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 JPG files to JPEG 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 JPEG file have?
+
Default behaviour is 1:1 — your JPEG output has the same pixel dimensions as the source JPG. ICO output is the exception (it produces a multi-resolution stack: 16/32/48/64/128/256). If you need to resize as part of the conversion, use /resize/ after conversion.
Are my JPG files private during conversion?
+
Yes. Uploaded JPG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted JPEG 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 JPEG file bigger / smaller than I expected?
+
Size is decided by the two compression models, not by the converter. Remember that JPG stores 8-bit RGB through a lossy DCT with 4:2:0 chroma subsampling by default, so fine red text and hard edges are the first things to soften, whereas JPEG is the same codec as JPG under a longer extension — identical DCT pipeline, identical quantisation tables, nothing about the pixels changes with the filename — so a heavily-compressed JPG usually GROWS when re-encoded into a lossless JPEG, and a bulky lossless JPG usually shrinks sharply going the other way. Image content matters too: photographs and flat line art compress very differently.
Can I use the converted JPEG file commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source JPG). We add no watermark, no metadata stamp, and claim no licence over the output.
