How we research, write, review and update content on PDF Compress. Our editorial standards, independence policy and corrections process.
We publish articles and tutorials to help people work with PDFs more easily. Every piece of content on this site is written and reviewed with the same goal: give the reader practical, accurate, and clearly explained information.
Our articles are written by the in-house editorial team, made up of people who use these tools every day and rely on them in their own work. Each author has a profile page that lists their background and the articles they have published.
Before writing on a topic, we work through it ourselves. We test compression settings on real files, try the same workflow on different operating systems and mobile devices, and check that every step actually works the way we describe. Where we cite a fact, we link to a primary source you can verify.
Every published article is reviewed by a second editor before it goes live. We re-review key articles at least every six months, or sooner when something changes that affects the advice we give. The "last updated" date shown on each article reflects the most recent review, not just a minor typo fix.
We do not accept payment for editorial placement and we do not let advertisers influence our recommendations. The site is supported by display advertising, which is clearly marked and separated from editorial content.
If you spot a mistake, please contact us. We correct factual errors as soon as they are confirmed and note significant corrections at the bottom of the article.
The compression tool processes your files automatically and deletes them shortly after. We never read, store, or share the contents of any PDF you upload. Full details are in our Privacy Policy.
