How to choose the right tool
Start with the file problem, not the file name. If the destination asks for a different format, use a converter such as JPG to PNG, PNG to JPG, Image to WebP, Image to PDF, or PDF to JPG. If the format is already accepted but the file is too large, use a compressor for JPG, PNG, WebP, or PDF. If the image looks poorly framed or the dimensions are wrong, use Resize Image or Crop Image before compressing.
For PDF workflows, choose the page action first. Merge PDFs when separate files need to become one document, Split PDF when only certain pages are needed, Organize PDF when pages are in the wrong order, Lock PDF when you need basic password protection, and Unlock PDF only when you have permission to remove a known restriction.
