Privacy Tips When Compressing Images for Online Forms
Many online compressors upload your images to a server. That is not always necessary. Web forms often reject attachments above a set size, and the error message is not always clear about why.
Recommended settings for online forms
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1000 px on the long edge |
| Quality | 70 |
| File size | 100 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Privacy Tips When Compressing Images
TheCompressJPEG processes images in your browser. Nothing is sent anywhere, which matters for IDs, documents and family photos.
Before sharing images for online forms, also check the picture itself: addresses, licence plates and documents in the background can reveal more than you intend.
Step by step with TheCompressJPEG
- Open the compress JPEG to 100 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 1000 and the target size to 100 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
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 online forms, the reliable recipe is simple: resize to around 1000 pixels, compress at quality 70 or to a 100 KB target, and check the result before you upload. Keep the original so you can always start again.
