JPEG vs PNG for DSLR Photos

Updated April 2, 2026 · 9 min read

Choosing the wrong format can make a file five times larger than it needs to be. Camera JPEGs straight off the card can be many megabytes each, which is heavy for sharing or web use.

Recommended settings for DSLR photos

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 3000 px on the long edge
Quality85
File size1000 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

JPEG vs PNG

JPEG is built for photographs with smooth gradients and noise. PNG is built for flat colours, sharp text and transparency. Saving a photo as PNG usually produces a much bigger file with no visible benefit.

For DSLR photos, use JPEG for photos and PNG only for logos, screenshots with lots of text, or images that need a transparent background. You can convert a PNG photo to JPEG here and often cut its size dramatically.

FAQ

Will compressing reduce image quality for e-learning courses?

Some detail is removed, but at sensible settings the difference is not visible at normal viewing size.

How do I compress many images for e-learning courses at once?

Drop all of them into the tool together and use Download all to get a single ZIP.

What JPEG quality should I use for e-learning courses?

Quality around 78 keeps photos looking natural while cutting file size substantially.

Wrapping up

For DSLR photos, the reliable recipe is simple: resize to around 3000 pixels, compress at quality 85 or to a 1000 KB target, and check the result before you upload. Keep the original so you can always start again.
