Guides — PDF, image & cyber café how-tos plus AI news
Practical how-tos for PDFs, images, QR codes and cyber café print jobs — plus longer reads on AI models when you need context before opening a calculator. Every task-focused guide links to a free PixelAndPDF tool that runs in your browser.
How our guides are built
Each how-to is written around a real job someone opens PixelAndPDF to finish: compress a PDF for a form upload, print an ID card on A4, unlock an e-Aadhaar file, or shrink a photo to a kilobyte cap. Steps are tested against the live tool, screenshots match the current UI, and the FAQ on every guide mirrors how people search.
Editorial articles cover AI product news — model releases, security incidents, prompt techniques — and link back to calculators or converters when there is a practical next step. They are dated journalism, not evergreen instructions, and sit in a separate list below so task guides stay easy to scan.
Pick the right guide
Start with a how-to when you know the outcome you need but not the clicks to get there. Open a cyber café guide when you are at a CSC desk handling Aadhaar, PAN or Ayushman print layouts. Open an image or PDF how-to when a portal rejected your file size or format. Open an AI article when you are researching model capability or cost before committing budget.

Frequently asked questions
What kind of guides does PixelAndPDF publish?
Two kinds: practical how-to pages for file tasks (PDF, images, QR codes, cyber café print jobs) and occasional editorial articles on AI models and industry news. How-tos always link to a matching free tool.
Are PixelAndPDF guides free to read?
Yes. Every guide is free with no paywall or sign-up. The linked tools are free as well and run in your browser.
Do guides replace the tools?
No. Guides explain the task — portal limits, print layout, password hints — then send you to the tool that finishes the job. Skim the steps if you are in a hurry; read the sections when something fails.
Which guides help with sarkari forms and cyber café work?
Look for how-tos on Aadhaar and PAN A4 print, Ayushman card layout, unlocking e-Aadhaar PDFs and resizing photos to 20 KB for government uploads. They pair with the Cyber Café Tools hub.
How often are guides updated?
How-tos are revised when portal rules, print sizes or tool defaults change. Each card shows an updated date. AI news articles are dated journalism — check the headline model or event for currency.
Who writes the guides?
Guides are written and reviewed by the same small team that builds the tools. Technical steps are tested against the live tool before publish; news pieces cite primary sources where possible.
Can I suggest a guide topic?
Yes. Email us from the contact page with the exact task you were trying to finish — for example a form upload limit or a printer layout — and we prioritise guides that match real visitor needs.
Why are some guides about ChatGPT or Gemini?
Those articles serve readers who land from AI news searches and need context before using our token cost calculator. They are clearly labelled and sit beside task-focused how-tos, not instead of them.
Do guides upload my files?
No. Guides are static pages. When you follow a link into a tool, processing still happens locally in your browser unless a page explicitly says otherwise.
Where should I start if I only need to compress a PDF?
Open the how-to on compressing a PDF to 200 KB for form upload, or the general reduce PDF file size guide, then use the linked Compress PDF tool when you are ready.
