Adjust JPEG quality
Use the quality slider to balance sharpness vs file size - 85% is a good starting point.

Resize and save
Click "Resize Image" then download your resized JPG.
Resizing JPEGs for sharing and web use
Camera and smartphone photos are often delivered at full sensor resolution - commonly 4000 pixels wide or larger - which is far more than is needed for sharing on social media, embedding in emails, or displaying on a website. Loading and displaying these full-resolution images is slow, consumes unnecessary bandwidth, and frequently causes upload failures on platforms with file size limits. Resizing to an appropriate dimension before sharing resolves all of these issues with no visible quality trade-off at typical display sizes.
For most purposes, a width between 1200 and 1920 pixels covers everything from social media posts to full-width website images, with file sizes that transfer quickly and display crisply. The quality slider gives you control over the balance between visual quality and file size - keeping quality at 85 to 92 percent produces output that is visually identical to the original at a fraction of the file size. If you need to target an exact output size in kilobytes, the resize to KB tool finds the right quality automatically.
Combining resize with compression
Resizing and compression are complementary operations. Reducing dimensions eliminates pixel data by changing the image's spatial resolution. Adjusting quality reduces file size by compressing the data that remains. Applying both together - resizing to a smaller dimension and then choosing a moderate quality level - produces the smallest practical file with the best visual result. For the most aggressive file size reduction, resize first, then run the compress JPG tool on the output to optimise the encoding.
