I'm sorry. The last message went out incomplete. I use this tool: https://www.xltoolbox.net/ With only one click (well... maybe two), you can generate high-resolution images especially for academic publication.

It can't be used in Mac.

I use the following method. Copy the excel graph and paste it in Microsoft image digital editor. By clicking on the section resize image, you can manipulate the resolution as well as size of the image. The same can be done in Photoshop also. It is not possible in MS paint. 

Thank you very much Sir 

Thank you SIr

Dear Muhammad,

my suggestion is to convert it into a vector format:

For this make sure you have a pdf printer installed. Mine came with the windows office package that I am using, but you can also download various versions for free from other sites. Rather then printing out on paper they will create a pdf (which is a scalable file) and save it. Select the graph you want to make into a pdf, select print and choose the pdf printer as the output device. You can then open the newly created pdf  file and manipulate it for example in inkscape or GIMP (free software) or adobe illustrator (costs) and save it as an SVG (scalable vector graphic). Inkscape for example will  also allow you to export back into another format when you have manipulated or scaled up the graph or you can import SVG files into many other applications.

Hope this helps.

Best wishes,

Immo

Thank you Sir

Hi, I have tried a couple of ways (as publication materials always require minimum of 300dpi for figures), and found that this way by University of Kent is the best. It works for me, and hope it will be helpful for you too.

You can follow the instructions in the link (again it is clear and step-by-step).

BR,

Thank you Sir

You may use graphpad prism program (free for one month) or licensed version it do it easily by copying the graph and pasting it in the program and export it with the desired resolution 300, 600, or 900 DPI.

Thank you Sir

Hi,

As an alternative method, if you install the Dplot you can easily plot any graph with different formats and resolutions. Once you install Dplot you would have an extension on the excel sheet, in add-ins tab.

The best, easiest and free way of doing it is to:

1. Select the graph you want to convert.

2. Go to "Print" and select "PDF Creator"

3. Press the "Print" option.

4. A new window of the default PDF Creator will open and direct you to save the image.

5. Select the appropriate profile TIFF, JPEG etc.. and change the resolution of the image through "Settings" option in the PDF Creator.

6. Lastly, SAVE the document to whatever location you need and VOILA you are done.

The best and fastest solution is the add-in for MS Excel proposed by Enrique G. Gordillo.

Thank you Enrique.

The best free online image converter into 300 dpi:

https://convert.town/image-dpi

I use xltoolbox

In Excel, right click on the graph and choose "Save as picture," and save it as a PDF file. Then open the PDF file and go to File>Export, and under Format choose JPG, then set the resolution to 300 pixels per inch and save. (I am using a MacBook so I'm not sure if this works on other computers)

Thank you

Dear all,

We faced with the same problem and solved it using IsfanView that can be downloaded for free from the official website: https://www.irfanview.com/

It tooks several minutes to solve the image resolution. We used "Image" and after "Resize/Resampling" and on the tool box you can install the needed DPI. After you save the picture in necessary format.

Yuliya

Thank you

Khulood Shattnawi's answer was the only one that worked for me.

I solved this issue simply copying and pasting the graph from Excel to MS PowerPoint, and then exporting a PDF from PowerPoint. The PDFs created by PowerPoint have (I don't know why, maybe some hidden settings) a better resolution than the ones exported from Excel.

I use Xltoolbox , but also we can use IrfanView a free program https://www.irfanview.com/ for converting many photo . You can convert images between different formats, also batch crop, change size, set dpi, change color depth and more. From file menu chose batch conversion,rename/advanced/set new dpi and set it to 300 or more. As shewn in the following screenshots

Also, we can use IrfanView for one image. You can use the following sequence, from file menu , open file, from image menu select resize/re-sample change dpi as you need. As shown in the following screenshots

Please see this video, How to Save Excel Graphs as High Quality Images

https://youtu.be/-NwYoayFJbs

You can directly convert plotted excel Plot/Chart from 96 dpi to 300, 600 dpi etc

It is a difficult option, but you can change the settings of the registry of PowerPoint. Here is a link were it is clearly explained.

Just try with the above link

After reading the comments here, I experimented within Excel and obtained sufficient quality. You could export a manually selected region including your chart as a pdf with the standard publishing option. Then, you need to crop the pdf using a vector graphics package (Inkscape). You would see you don't actually need to use any of the external software mentioned under this post.

After reading here, without installing anything, I have found how obtain a .tiff file with at least 300dpi:

Copy and paste the graph in PowerPoint (in a page (large))

- You make PDF

- Save the PDF with "save as another..", choose image and TIFF, there, there are settings, including resolution which you can change: with 118.11 pixels/cm it has come out just right (300 dpi), but you can put much more

The primitive but fast way is to take a screenshot (if you just need a jpg picture).

I would follow Sarah Ebert advise however Acrobat Reader in Windows usually does not have funcionality as in MacOS (save as BMP/TIFF/JPEG etc.). For this purpose I use PaperPort but it's not cost effective.

I do not see any chance in MS products to save as bit map (forget about any resolution setting).

Thank you

Dear Colleagues,

In LibreOffice there is a good exporting tool for charts into JPG/PNG raster formats. Brief instructions:

a) select a chart (created in the working sheet) you want to save in JPG/PNG.

b) Go to FIle -> Export -> Check box "Selection" -> Select a format -> Press "Save" button -> Modify resolution to 300 dpi -> Modify WIdth or Height -> Change to minimum compression (highest quality) -> Press "OK" button.

Final result: JPG/PNG image with 300 dpi resolution.

Thank you

This works well https://www.motifolio.com/tips2.html

Dear Muhammad Saleem,

In the first step you should save your Excel graph as a PDF file.

then, import the mentioned PDF file in the Photoshop program and set the resolution on 300 Pixels/Inch and finally save it as Jpg, Bmp or any other formats you need.
