Frequently asked questions about JPG and JPEG compression
How do I compress a JPG image online?
Select your JPG or JPEG image in SWD Image Compressor and run compression. SWD Image Compressor keeps the original dimensions and applies the maximum compression available for the format from the start.
What is the difference between JPG and JPEG?
JPG and JPEG refer to the same image format. The difference is the file extension: .jpg and .jpeg both represent JPEG images.
Does compressing a JPG change its dimensions?
In SWD Image Compressor Compression, compression keeps the image width and height. Resizing is a separate operation.
Can I compress a JPG without visible quality loss?
SWD Image Compressor aims to reduce file size with minimal visible quality loss. Because JPEG is a lossy format, zero loss cannot be guaranteed for every image.
Why do some JPG files barely get smaller?
A JPG may already be highly optimized or previously compressed. In those cases, further reduction can be small or require more visible quality loss.
Does SWD Image Compressor look for the maximum possible compression for a JPG?
Yes. SWD Image Compressor works directly with the maximum compression available for the format from the start of the process. There is no prior recommended-compression mode or choice between two compression levels.
Can SWD Image Compressor generate WebP or AVIF when compressing a JPG?
When the Compression settings allow it, SWD Image Compressor can evaluate compatible formats and select a more efficient result than the original JPG.
When should I keep JPG as the final format?
JPG remains a good choice for photographs and environments where very broad compatibility matters. The best final format depends on the image and its intended use.
Can repeatedly compressing the same JPG reduce quality?
Yes. JPEG uses lossy compression, so repeated re-encoding can accumulate degradation. Working from the original file is preferable whenever possible.
What happens if my JPG is already well compressed?
If additional compression, whether in JPG or another compatible format, does not provide a worthwhile improvement, SWD Image Compressor will indicate this instead of presenting a result that is not worth it as an optimization.
