JPEG vs PNG for Cloud Backups

Updated August 31, 2026 · 6 min read

Choosing the wrong format can make a file five times larger than it needs to be. Backups of large photo libraries upload faster and take less quota when files are sensibly compressed.

Recommended settings for cloud backups

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 cloud backups, 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

What size should an image be for e-learning courses?

A practical default is about 1600 pixels wide and 200 KB or less, unless the destination states its own limits.

Can I compress images for e-learning courses without uploading them?

Yes. TheCompressJPEG runs entirely in your browser, so your images never leave your device.

Is WebP accepted for e-learning courses?

It depends on the platform. JPEG is the safest choice when you are not sure.

Wrapping up

For cloud backups, 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.
