How to choose the right online tool
First, identify the result you need. PDF compression is used to reduce document file size, merging combines separate PDF documents, and image resizing changes an image's dimensions. Image compression, on the other hand, focuses on reducing its file size.
Checking these differences before starting can help you select the right workflow and avoid unnecessary conversions.
Check your file before sharing
After processing a document or image, review the result before uploading or sending it. Check that text is readable, pages appear in the intended order, images have suitable dimensions, and the output meets the destination's requirements.
For applications and official submissions, always follow the file format, file-size, and document requirements provided by the receiving organization.
