Compress JPG — Reduce File Size in Your Browser
Runs in your browser — your photos are never uploaded to our servers.
- Files never leave your device
- No signup · Free in-browser conversion
Why Compress JPG Locally?
Camera and scanner JPGs are often larger than portals allow. Re-encoding at lower quality—or with a max-width preset—cuts bytes without sending photos to a cloud compressor.
Most online "compress JPG" sites upload your files. HeicSave re-encodes in your tab with JavaScript and Canvas—your bytes never hit our servers.
Use batch mode for folders of receipts, ID scans, or vacation photos before attaching to email or submitting forms.
How to convert (JPG → JPG) in 3 steps
- Drop JPG/JPEG files. Set quality (default 75%) and optional max width.
- Click Compress. Re-encoding runs locally—nothing is uploaded.
- Download smaller JPGs individually or as a ZIP.
Privacy: Files never leave your browser
Compression re-encodes JPG in your browser. We do not receive your image data.
Compress JPG for email and portal upload limits
Government forms, university portals, and HR systems often cap file size at 2–5 MB. Compress locally first instead of trusting random upload sites with personal documents.
