A LITTLE KNOW-HOW GOES A LONG WAY

Good files start with good advice.

Practical guides for the things you actually need to get done. No complicated terminology required.

Spreadsheet printing

Excel to PDF without cutting off columns

Fix XLSX print areas, page width, blank pages and tiny text before converting a spreadsheet to PDF.

Presentation sharing

PPTX to PDF: fix changed fonts and choose the right handout

Decide between slide pages, speaker notes and multi-slide handouts, then check fonts, diagrams and media in your PDF.

Page order

Repeat a PDF page multiple times or place its copy at the end

Use page-number examples to choose Duplicate Pages or Organize PDF, preserve the originals and check the final order.

Application documents

Prepare a photo and signature for an online application

Match the portal’s pixel dimensions, file format and KB limits without stretching your photo or signature.

Application documents

Reduce a scanned PDF for a 100 KB or 200 KB upload limit

Use a target-size search, understand image-only output and decide when further compression makes a scan unreadable.

Application documents

Check a PDF before submitting an application

Check file size, page count, orientation and likely blank pages, then review content the automated check cannot judge.

OCR & language

Make a Hindi scanned PDF searchable with OCR

Choose Hindi OCR, improve the source scan and verify names and numbers before relying on recognized text.

Mobile documents

Turn phone photos into a readable application PDF

Photograph pages clearly, choose page order and create a PDF without assuming a photograph is a certified scan.

Printing

Put the front and back of a card on one A4 sheet

Prepare a neat front/back sheet, preserve image proportions and print it at the intended scale.

Application documents

Combine certificates in the order an application asks for

Create one ordered PDF from certificates while checking reverse sides, page sizes and signed originals.

Document safety

A typed signature is different from a certificate-backed digital signature

Choose the right signing method for the recipient and understand what a visible signature mark does not prove.

Document safety

Use PDF tools more carefully on a shared computer

Understand local processing, temporary uploads, downloads and browser storage when working at a cyber café or shared workstation.

Application documents

Choose JPG, PNG or WebP for an application upload

Convert the actual image format instead of renaming an extension, and check transparency, dimensions and accepted file types.

Privacy & productivity

How to merge PDFs without uploading your documents

Combine attachments on your own device, put the pages in order, and keep your originals.

Smaller files

A smaller PDF without an unpleasant surprise

When to use lossless optimization, when scans benefit from image compression, and what to check.

Document safety

Cropping is not redaction. Here’s the difference.

Understand what actually removes sensitive information before you share a PDF.

Conversion basics

PDF to Word: what an editable conversion can—and can’t—do

Choose the right conversion for text documents, scanned pages and complicated layouts.

Everyday workflows

Prepare a polished PDF attachment in one workflow

Combine, number and optimize a document before you attach it to an email.

Image essentials

JPG, PNG or WebP? A practical guide to smaller images.

Pick a format based on the image, the background and where it will be used.
