Free PDF tools

Good to know

• Combining scanned pages or phone photos into one PDF makes it easier to upload documents to forms that accept a single file.
• PDF to Word conversion works best on text documents such as resumes and letters; tables, images and complex layouts rarely come across exactly.
• Sending a resume as a PDF keeps its layout the same on every device, while text stays selectable for recruiters and screening software.
• Many job and admission forms accept only one document upload, so merging your resume, certificates and mark sheets into one PDF saves effort.
• Page ranges are written with commas and hyphens, such as 1-3, 5, 8-10, with the smaller page number first in each range.
• Job portals and government forms often cap PDF uploads at a few hundred KB; the limit varies, so check the size stated on the form first.
• For PDF pages turned into images, 150 DPI suits sharing and uploads, while 300 DPI gives print quality at a much larger file size.
• Rotating a page in a PDF viewer often changes only the view; saving a rotated copy fixes the page for everyone who opens the file.
• Removing blank or duplicate pages and putting documents in a clear order makes a PDF quicker to review and smaller to upload.
• Page numbers help reviewers refer to a specific page of a long application, report or set of certificates, especially when it is printed.
• Stamping “For verification only” on ID or certificate copies shows the purpose they were shared for and discourages misuse elsewhere.
