from 96dpi screen shot
with no extra software

2. Premise
• Screen captures are typically 96dpi (screen) resolution
• That works for computer-to-computer presentations etc.
• Submit a publication, map or calendar?
• Requirement of 300dpi typically more important than the file format
• Photoshop etc. allow to do that if you have them
• But here’s a technique using Micosoft Paint in Windows

3. Post a 300dpi image (target) and your 96 dpi
image (source) side by side on your desktop
Target Source

4. Verify the resolution of each image, select in
top menu File > Properties
Target Source

5. If not already JPEG, “Save as…” that format so
you can read dpi’s (no image degradation)
Target Source

6. Copy&paste the dimensions of the source
into those of the target
Target Source

7. Copy&paste source image into target frame:
click source Ctrl-A + Ctrl-C, then target Ctrl-V
Target Source

8. Target “Save as…”, say, {source name}300.jpg
Voilà! You now have a 300dpi version to use…
Target Source

9. Verify in Windows Explorer that is the case
Target Source
