An image's dimensions, framing, format and file size solve different problems. Pick the operation that matches your goal, or use a short sequence when preparing pictures for a website, document or review.
Crop to change the framing, resize to reach the required pixel dimensions, then compress to reduce the download size. The format converter is useful when you need a different supported output format rather than a different composition.
Use the aspect ratio calculator to work out proportional dimensions before editing. For an overview of several pictures, the contact-sheet maker arranges them into a labelled grid instead of making you open every file separately.
Image to PDF assembles image files into a document. PDF to JPG renders document pages as image files when you need a visual preview or an image to work with in another tool.

Open toolResizing changes pixel dimensions; cropping removes parts of the picture. An aspect ratio calculation plans the geometry but does not edit the image itself.
Compression and format conversion may change image quality or transparency. Check the preview and output settings before replacing an original. A smaller pixel count often helps more than repeated compression.
