Platform Guides: Common Questions
What are platform-specific compression guides?
They are step-by-step instructions for preparing images, video, and PDF files to meet the exact size, dimension, and format requirements of a given platform such as Instagram, Twitter, WhatsApp, WordPress, or email. Each guide covers the recommended resolution, aspect ratio, and compression settings so your files upload cleanly and display sharply.
Why does each platform need different image sizes?
Every platform resizes and re-compresses uploads to fit its own layout and bandwidth limits. Uploading at the platform's target dimensions avoids a second lossy compression pass, so your image stays sharp. Twitter, Instagram, and WordPress each crop and scale differently, which is why matching the correct size for each one gives the best visible result.
Do these guides work on mobile and desktop?
Yes. Every FileFormer tool runs entirely in the browser, so the same compression and resizing steps work on a phone, tablet, or computer with no app to install. You upload a file, apply the recommended settings from the guide, and download the optimized result directly on whatever device you are using.
Will compressing for a platform reduce quality?
Compressing to a platform's target size preserves more quality than letting the platform do it automatically. By following each guide's recommended settings you control the trade-off yourself, keeping detail where it matters while cutting file size. The result usually looks better than an unoptimized upload that the platform re-compresses on its own.
