JPEG Optimizer
JPEG Optimizer without uploading it
Load a JPEG and this page strips its metadata losslessly (EXIF, XMP, ICC, comments - pixels untouched), then re-encodes it on a canvas at the quality you choose with an optional width cap. No library, no server, no upload. Honest limits: every re-encode loses a little detail, the re-encode drops EXIF orientation and the embedded ICC profile, and a JPEG that was already optimized can come out larger.
- JPEG is already lossy - every re-encode loses a little detail, so use the highest quality that still meets your size goal.
- The lossless strip removes EXIF, XMP and comments without touching a single pixel - try it before lowering quality.
- EXIF orientation is the one metadata field you may care about: the re-encode bakes the rotation into the pixels, the strip drops the tag.
- Quality 80 to 90% suits photos; below 50% shows visible artifacts on most images.
- Capping the width shrinks the file far more than trimming a few quality points.
- Stripped files no longer carry camera model, lens, GPS and timestamps - that private data stays out of the shared copy.
- An embedded ICC profile is dropped by the re-encode, so wide-gamut photos can shift color slightly.
- Progressive JPEGs interleave scans for fast display; the lossless strip keeps that structure, the re-encode writes a baseline JPEG.
- Screenshots with flat colors shrink differently from noisy photos - there is no single best quality number.
- The optimization runs on this page: your file is read, optimized and downloaded, never uploaded.
- Check both results before downloading: if the re-encode grew, the lossless strip alone may still save bytes.
