Compress JPG Files

How to compress a JPG

1. Select one or more .jpg / .jpeg files.
2. Choose a quality level — the preview updates with the projected size.
3. Compress, then download each file or grab the whole batch as a ZIP.

Why JPG files get so large

Modern phone cameras write JPEGs at very high quality settings — often the equivalent of quality 95 or higher. That last 5% of quality can account for more than half the file size, because JPEG's cost curve is steep at the top end.

Dropping from quality 95 to quality 80 typically removes 60–70% of the bytes while remaining visually indistinguishable on a phone or laptop screen. That is why re-compressing a camera JPEG is usually free money.

What happens to EXIF data?

Re-encoding rebuilds the file from the decoded pixels, so camera metadata, timestamps and GPS coordinates are not carried over. Rotation recorded in the EXIF orientation tag is applied first, so the picture keeps the right way up.

If stripping metadata is your actual goal and you would rather not re-compress at all, the metadata remover does it losslessly.

Progressive vs baseline JPEG

Browsers encode baseline JPEG through the Canvas API. Progressive JPEGs — the kind that fade in from blurry to sharp — are marginally smaller but cannot be produced with the browser encoder. For web delivery, converting to WebP saves far more than progressive encoding ever would.
