Compress JPEGs to the size you need.

JPEG compression reduces a photo’s file size by discarding image detail that is hard for the human eye to notice. Smaller files upload faster and fit form limits — but the trade-off is lossy, so very aggressive settings make images visibly softer.

Drop your JPEG into the upload zone above, or choose files from your device (you can also paste with Ctrl/⌘ + V). The editor opens with your images — pick Smart, Quality, or Target Size, press Compress, then download the result.

Yes, JPEG compression is lossy — some data is permanently removed. At Smart Balanced (quality 80), the difference is invisible for most photos. Maximum Savings is visibly softer but much smaller. The before/after comparison shows you exactly what changed.

Typically 60–80% at Balanced. A 4 MB phone photo usually becomes roughly 1 MB. Busy, detailed photos compress less than simple ones. The result screen always shows original → compressed size, percentage, and bytes saved.

Yes — up to 20 images. They are processed one at a time so large batches don’t freeze your browser. Download individually or all together as a ZIP file.

Nothing — they are the same format. This tool handles .jpg and .jpeg identically.

Almost always. 100KB leaves reasonable room for quality on typical photos, and the tool bisects quality (up to 8 encodes) for the highest setting that fits.

Choose the Target Size mode and pick 200 KB (or type a custom size). The tool bisects JPEG quality (up to 8 encodes) for the highest quality that fits under your limit. If it cannot fit without ruining the photo, it will say so and suggest enabling Resize instead of silently destroying quality.

Yes. The compressor runs in the browser, so it works the same on Android, iPhone, and tablets — pick a photo, choose a size or quality, and download the result.

Yes, completely free. No account, no watermark, no signup. Your originals are never modified — downloads are saved as name-compressed.jpg.

Yes. Compression runs locally in your browser — image bytes are never uploaded to our servers. The compression library itself loads from a CDN, so the page needs internet once, but your photos never leave your device.
