Should You Strip EXIF Data From Images for Mobile Apps?
Photos carry hidden metadata such as camera model, date and sometimes GPS location. App screens are small and users are often on cellular data, so oversized images waste bandwidth and battery.
Recommended settings for mobile apps
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1080 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Should You Strip EXIF Data From Images
For anything shared publicly, removing that data protects your privacy and shaves a few kilobytes. For mobile apps, there is rarely a reason to keep it.
When our tool re-encodes an image through the browser canvas, metadata is not carried over, so the downloaded file is clean by default.
Step by step with TheCompressJPEG
- Open the compress JPEG to 150 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1080 and the target size to 150 KB.
- Press Compress, check the result and download it.
Quick tips
- Write a size limit slightly below the stated maximum to leave a margin.
- Process private images locally rather than uploading them to unknown servers.
- Crop out distractions so pixels go to the subject.
- Use WebP where it is supported and you control the page.
FAQ
Is WebP accepted for e-learning courses?
It depends on the platform. JPEG is the safest choice when you are not sure.
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.
Wrapping up
For mobile apps, the reliable recipe is simple: resize to around 1080 pixels, compress at quality 70 or to a 150 KB target, and check the result before you upload. Keep the original so you can always start again.
