Shrink JPG or PNG file size, keep quality.
Reduce JPG or PNG file size for faster uploads, email attachments and web use by balancing image dimensions and encoding quality.
Best for: Photos and screenshots that are larger than needed for their destination.
File size is influenced by pixel dimensions, image complexity and compression settings. Lower JPEG quality often saves more space; PNG behaves differently and is better for graphics that need lossless edges or transparency.
Re-encodes the selected image in the browser at a chosen quality level. Lossy formats reduce size by discarding visual detail; savings depend on the original format and content.
Keep a lossless master when the image will be edited repeatedly or printed at high quality.
This section describes the implementation shipped with My Tools HQ. Verify important outputs before relying on them.

There is no universal number. Start high, inspect the result, and reduce until file size meets your target without objectionable artifacts.
PNG uses lossless compression and can be inefficient for detailed photos. Converting a photo to JPEG or WebP can save more space.
Not necessarily. Removing unnecessary pixel dimensions can cut file size dramatically with no visible loss at the intended display size.
Understand the three main levers that determine whether an image is genuinely optimized or merely damaged.
