Compress JPG Online for Free
Camera photos and phone screenshots saved as JPG can easily run several megabytes each, which adds up fast once you're storing a whole photo library, attaching images to emails, or uploading a gallery to a website. This tool compresses JPG files directly in your browser, cutting file size down while keeping enough detail that the difference is hard to spot at normal viewing sizes.
JPG compression works by discarding some of the fine detail our eyes are least sensitive to, so a moderate reduction in quality often produces a file that's a fraction of the size with no visible loss. Use the quality slider to dial in how aggressive that trade-off is, or set an optional target size in MB and let the tool find a quality level that lands close to it automatically.
Because everything runs locally using your browser's own processing power, your photos are never uploaded to a server — compression happens locally via the Canvas API, so nothing is uploaded, even on large batches. Drop in a single photo or hundreds at once; multiple files are compressed independently and bundled into one zip for download. There's no account, no daily limit, and no watermark added to your images.
Common questions
Cameras and phones typically save JPGs at very high quality settings to preserve maximum detail, resulting in files several megabytes in size. Most of that detail is unnecessary for screens or web use, which is exactly what compression trims away.
Re-encoding a JPG through the browser's Canvas API produces a fresh file, which typically does not carry over EXIF metadata like camera settings or GPS location — useful if you want to strip that data before sharing.
For web galleries, 65-80% quality is usually the sweet spot — file sizes drop substantially while photos still look crisp on typical screens. Go higher if the images will be viewed full-screen or printed.
Yes — set a target size in the optional MB field and it applies to every file you drop in. Each image is compressed independently toward that target and bundled into a single zip download.
Yes, you can drop in JPGs directly from your phone's camera roll or a synced folder. Compression happens entirely on your device, so it works even on a slow connection.
