![]() If you want to do the work again, you can edit your original JPEG files that you kept. Don't overwrite your original JPEG files - keep these. However, in your case it probably won't make much difference, and won't be that noticeable. You can export your image as a JPEG again - although it's not a particularly good idea to edit jpegs repeatedly, and save them again, because the quality will degrade slightly each time. You might not want to save XCF files if you don't need to edit the image again. Some new professional cameras produce RAW files in excess of 40mb per image! I frequently retouch professional images, and it's not uncommon to end up with Photoshop PSD files that are 300mb! Honestly, these days 23mb is not really a large image size. You can buy external 1TB hard drives for less than £50GBP/€56/US$65. When I do the same in GIMP with the same image, the XCF is 861kb.Īlso note that if you add layers to the original image, the file size will get much bigger - essentially, each layer is a new image.Īs for disk space - external hard drives are cheap. Opening in Photoshop, and saving as a PSD (Photoshop's native file format) the files size is 889kb - that's more than 8 times bigger. The same thing happens if you open a JPEG in Photoshop, and save as a PSD (ie Photoshop's native file format).įor example, I open this JPEG in Photoshop shown below. When you save the file as XCF, ie GIMP's native file format, it is an uncompressed format, so the file size will be much bigger than a JPEG. When you open a JPEG in a raster image editor such as GIMP or Photoshop the compressed image is expanded to full size - it's no longer a compressed JPEG. Don't confuse JPEGs that come out of your camera with RAW files. RAW images are unprocessed images from a camera, such as NEF, CR2, or DNG formats. ![]() JPEG is a format which has lossy compression. Since you are relatively new to this, your confusion is understandable. What you are describing is completely normal, and to be expected.
