How it works
Why compress JPG?
Balance JPG quality against file size, ideal for email, uploads and storage. JPG is lossy so lowering quality discards invisible detail while keeping photos usable.
How JPG compression works
JPG is a lossy format, so compression reduces file size by discarding some visual detail. Higher quality settings preserve more detail but produce larger files.
Quality settings explained
The balanced preset balances quality and file size for most uses. Lower quality settings cut size further but introduce more compression artifacts.
Is compression private?
JPG compression runs entirely in your browser. Your photo is re-encoded locally and never uploaded.
Batch compress JPG
Compress several JPG files in one go to slash their total size. Free, private, batch ZIP, and every image is processed locally in your browser.
Frequently asked questions
How much can I shrink a JPG?
Typically 30 to 60 percent at balanced quality without noticeable loss. More at lower quality settings.
Will compressing JPG reduce quality
Yes a little, JPG is lossy. Balanced keeps detail well, go lower only when a size limit forces you. Try resize JPG first before lowering quality.
Can I bulk compress many JPGs without uploading
Yes. Add your JPG folder, pick balanced, and compress together. All files re encode locally and you can download a ZIP.
