This page explains who is behind this site, how we test the tools and check the facts in our guides, and why the site exists.
Who makes this site
This is an independent site. The same people who build the tools write the guides, and everything is published under the site’s name. We’re not connected to Instagram, Meta, TikTok or ByteDance, and nobody pays us to recommend anything.
How we test the tools
Before an update goes live, we run every tool and check what it actually produces, not just how it looks on screen.
- Sizes are measured. We open the exported files and check their exact pixel size, for example 1080 × 1440 for a grid tile or 1080 × 1920 for a Reel.
- Seams are compared. For grids, banners and carousels, we compare the pixels on both sides of every cut. If a picture jumps at a seam, the update doesn’t go out.
- Videos are inspected. For the video grid maker, we check the size, frame rate, length and frame count of every file, and look at matching frames from neighbouring tiles side by side.
- Blur results are checked. We run the face blur tool on group photos with faces of different sizes, and compare the saved file with the original to make sure nothing outside the blurred areas has changed.
- Phones come first. Most people use these tools on a phone, so we check each tool in current versions of Chrome and Safari on phones as well as computers.
The figures on each tool page show real exports from these checks.
How we check sizes and facts
Sizes and rules come from the platforms’ own announcements and help pages wherever they exist, and our guides link to their sources. When a platform hasn’t published something, like the exact shape of TikTok’s profile thumbnails, we say so plainly and explain how to check it on your own profile. Every size the tools use can be changed in one place, so when a platform changes its layout we can update the tools and the guides together.
Keeping pages up to date
Each page shows the date it was last updated. If you spot something that’s wrong or out of date, please tell us on the contact page. We fix mistakes as soon as we’ve checked them.
Why this site exists
Instagram’s switch to a taller profile grid left a lot of people with grids that no longer lined up. We built these tools to fix that, and we write the guides to answer the questions people actually ask while using them. The tools are free and the site is paid for by ads. Ads never decide what we write, and they’re never placed next to the upload or download buttons.
