Guides: how to compress, convert and share files
Short, practical guides for the jobs people search for most: HEIC on Android, PDFs under a size limit, photos for online forms, QR codes and video for WhatsApp. Each guide links to the free tool that does the job in your browser.
How to convert HEIC to JPG on Android
iPhone photos arrive as HEIC and will not open on many Android phones. Three ways to turn them into JPG, including one that needs no app and never uploads the photo.
How to compress a PDF without losing quality
Why PDFs get big, which compression keeps text sharp and searchable, and how to hit a size limit such as 500 KB or 1 MB while keeping the document readable.
How to reduce image size for online forms
Government, exam and job portals reject photos over 20, 50 or 100 KB. How to meet the limit in KB and pixels without a blurry result, step by step on a phone.
How to convert images to PDF
Turn one photo or a whole set of JPG, PNG or HEIC images into a single PDF with pages in order, the right paper size, and a file small enough to upload or e-mail.
How to create a QR code for free
Make a QR code for a link, Wi-Fi network, phone number or text that never expires, print it at the right size, and avoid the free-trial traps that break codes after 14 days.
How to send large videos on WhatsApp
Why WhatsApp makes videos blurry, the 16 MB rule, how to compress a clip so it arrives sharp, and when to send as a document instead.
