Decision guide
Know what the result can and cannot do
Compression is a trade-off between byte size, pixel dimensions, and visible detail. Resize to the real display size first, then lower quality only as far as the image can tolerate.
Best for
- Website and marketplace uploads
- Email attachments with size limits
- Lighter sharing copies while keeping the original
Watch for
- Text and thin lines can show artifacts before photos do
- PNG may stay large when transparency is required
- Repeated JPG exports compound quality loss
Before you share
- Compare dimensions as well as file size
- Inspect faces, text, and high-contrast edges at 100%
- Keep the source file until the result is accepted
Try this scenario
Judge the delivery copy, not only the size number
A smaller file is useful only when the destination can still read and display it correctly.- Try it with
- Reduce a camera JPEG to a 1600px delivery copy for a page or message.
- Check before sharing
-
- Compare text, faces, gradients, and fine edges at 100%
- Reopen the download and confirm dimensions, format, and file size
