convert jpg to pdf

  • 772

in my Ubuntu 19.10 when trying to convert .jpg to .pdf :

convert gives :

joso@joso-Aspire-ES1-433:~$ convert ‘/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg’ output.pdf
convert: no decode delegate for this image format `JPG’ @ error/constitute.c/ReadImage/562.
convert: no images defined `output.pdf’ @ error/convert.c/ConvertImageCommand/3273.

I can open jpg file. In terminal:

joso@joso-Aspire-ES1-433:~$ file /home/joso/Desktop/Marticeva\ etaziranje/IMG_20200104_102541.jpg
/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg: JPEG image data, Exif standard: [TIFF image data, big-endian, direntries=10, manufacturer=HUAWEI, model=ATU-L21, xresolution=150, yresolution=158, resolutionunit=2, software=ATU-L21-user 8.0.0 HUAWEIATU-L21 156(C432) release-keys, datetime=2020:01:04 10:25:41, GPS-Data], baseline, precision 8, 3120x4160, components 3
joso@joso-Aspire-ES1-433:~$

using command :

joso@joso-Aspire-ES1-433:~$ cp /home/joso/Desktop/Marticeva\ etaziranje/IMG_20200104_102541.jpg foo.jpg; convert foo.jpg foo.pdf 
convert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. 
convert: no images definedfoo.pdf' @ error/convert.c/ConvertImageCommand/3273. 
joso@joso-Aspire-ES1-433:~$

still the same, no success.

I tried with 2 other files:

joso@joso-Aspire-ES1-433:~$ convert '/home/joso/Pictures/IMG_20191214_120216.jpg'  output.pdf
convert: no decode delegate for this image format `JPG' @ error/constitute.c/ReadImage/562.
convert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.

joso@joso-Aspire-ES1-433:~$ convert '/home/joso/Pictures/John Selman2.jpeg' output.pdf
convert: no decode delegate for this image format `JPEG' @ error/constitute.c/ReadImage/562.
convert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.

joso@joso-Aspire-ES1-433:~$ convert /home/joso/Pictures/IMG_20191214_120216.jpg output.pdf
convert: no decode delegate for this image format `JPG' @ error/constitute.c/ReadImage/562.
convert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.
joso@joso-Aspire-ES1-433:~$ 


joso@joso-Aspire-ES1-433:~$ convert -compress jpeg /home/joso/Pictures/IMG_20191214_120216.jpg /home/joso/Pictures/output.pdf convert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. convert: no images defined/home/joso/Pictures/output.pdf' @ error/convert.c/ConvertImageCommand/3273.

I can open the file in an image viewer and file reports it's a normal jpg:

$ file /home/joso/Desktop/Marticeva\ etaziranje/IMG_20200104_102541.jpg 
/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg: JPEG image data, Exif standard: [TIFF image data, big-endian, direntries=10, manufacturer=HUAWEI, model=ATU-L21, xresolution=150, yresolution=158, resolutionunit=2, software=ATU-L21-user 8.0.0 HUAWEIATU-L21 156(C432) release-keys, datetime=2020:01:04 10:25:41, GPS-Data], baseline, precision 8, 3120x4160, components 3

I also tried this as suggested in the comments:

$ convert -compress jpeg /home/joso/Pictures/IMG_20191214_120216.jpg    
/home/joso/Pictures/output.pdf convert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. convert: no images defined/home/joso/Pictures/output.pdf' @ error/convert.c/ConvertImageCommand/3273.

What am I doing wrong?

pdf convert imagemagick

  1. Keep it simple. Open your jpg file with libre office draw (or impress). Once open in the menu "file" (i suppose in English) export this file with " export as pdf")

    • 3 
  2. sudo apt-get install imagemagick

    then you use somethin like this with the files in WORKINGDIRECTORY (cd /path/to/workingdirectory/)

    convert input.jpg output.pdf

    if it aint working like u aint got permission or somethin u gotta change the config file to allow that convert function to do that. you do that by sain sudo nano /etc/ImageMagick-6/policy.xml and then you go to hashtag out this line <policy domain="coder" rights="none" pattern="PDF" /> and maybe the JPG line too.
