People use our guides right before a deadline, often for an exam or job form that matters a lot to them. One wrong number, such as the wrong photo size, can mean a rejected application. So we hold every guide to the standards on this page.
Our goal
Every guide should help you finish your task correctly the first time. If a reader still needs to search elsewhere after reading our page, we have not done our job.
Where our information comes from
We rely on primary sources first. In order of trust:
- Official notifications and portals. For upload rules, we read the latest notification from the organization itself, such as the SSC, UPSC, IBPS, NTA, or Passport Seva website.
- Official technical documentation. For file formats and browser behavior, we use sources such as Google’s developer documentation, Mozilla’s MDN Web Docs, and Adobe’s PDF documentation.
- Our own testing. We run every method on real files before we recommend it.
We link to these sources inside our guides, so you can check them yourself.
How we test
Before we publish a how to guide, we follow every step ourselves. In particular, we:
- Test on both Android phones and Windows computers, and on iPhone or Mac when the guide covers them
- Use realistic files, such as phone camera photos, scanned signatures, and multi page scanned PDFs
- Record the original size, the target size, and the final size we achieved
- Check that text stays readable and faces stay clear after compression
If a method does not work reliably in our tests, we leave it out.
How we keep guides accurate
Upload rules change with every new exam cycle. Because of that, we:
- Show a “last updated” date on every guide
- Review our most visited guides regularly and whenever a new notification comes out
- Fix reported errors as fast as we can, usually within a few days
Corrections
We sometimes get things wrong. When we do, we fix the error and, for meaningful changes, note what changed and when. If you spot a mistake, please email compresspdfto200kb@gmail.com with “Correction” in the subject line and a link to the page.
How we use AI
We may use AI writing tools to help organize research or draft an outline. However, a person on our team checks every fact, tests every step, and edits every page before it goes live. We never publish AI output without that human review, and we never use AI to invent test results or experiences.
Ads and independence
We earn money from Google AdSense ads. However, advertisers have no say in what we write. Google chooses which ads appear, and we do not write guides to promote an advertiser.
When we compare our tool with others, such as iLovePDF, Adobe Acrobat, or Smallpdf, we describe each one fairly, including where another tool does something better. If we ever add affiliate links, we will label them clearly, and a commission will never change our recommendation.
Writing style
We write the way we would explain things to a friend: short sentences, plain words, and clear steps. We skip filler so you can get back to your form quickly.
