How to compress a JPG
- 1. Add your JPG images. Select one photo or a complete batch from your device.
- 2. Choose the result. Set the JPG quality and keep the original dimensions or resize them.
- 3. Compare and download. See the original size, compressed size, and saving before downloading.
Smaller JPGs for everyday uploads
A smaller JPG is quicker to upload to websites, forms, ecommerce stores, and content management systems. It also uses less storage and is easier to attach to email. You choose the quality and dimensions, while your original image stays unchanged.
Need to hit a specific file size instead?
If a job portal, university admission form, or government system requires a photo under a specific size like 100KB, use a target-size compressor instead of the quality slider above. It finds the right quality automatically so you don't have to guess.

Frequently Asked Questions
How does JPG compression work?
The quality setting controls how much image detail is used when the JPG is encoded again. Lower settings generally create smaller files. Crest Convert shows the completed size and total saving so you can choose the result that suits your use case.
Which JPG quality setting should I choose?
Start around 80% for a practical balance, then move higher for detailed photographs or lower when a compact upload matters most. The original JPG remains unchanged on your device.
Is this compressor safe?
Yes. Compression happens entirely in your browser. Your images are never uploaded to Crest Convert or stored on our servers.
Can I compress multiple JPGs at once?
Yes. Add multiple JPG or JPEG files, apply one quality and size setting, then download each result separately or together as a ZIP archive.
Can I resize a JPG while compressing it?
Yes. Resize from 10% to 100% with the output-size slider. Both dimensions change together, which is useful for web uploads, email, and forms that do not need the original resolution.
Can I compress a JPG to a specific file size?
Yes. Use the dedicated target-size compressor when a form requires a limit such as 100KB or 1MB. It searches for an appropriate quality setting automatically.
Will the compressed JPG keep its metadata?
The compressed file keeps the visible photo but does not copy EXIF details such as the camera model, date taken, or GPS location. Keep the original JPG when you want to retain that information.
Why did my JPG not become much smaller?
A JPG that has already been heavily compressed may have little unused data left to remove. Try a lower quality or smaller output dimensions, then compare the original and completed sizes shown by the compressor.
