About FileFit Tools

What we are building

File upload limits and format requirements can turn a simple form into a frustrating task. FileFit focuses on practical tools such as image compression, exact pixel resizing, PDF page work and file conversion.

Privacy-first design

The tools in this build perform file processing in the browser instead of sending selected files to a FileFit upload server. Some tools load JavaScript libraries from third-party content delivery networks, so your browser may connect to those providers to load code.

Accuracy and limitations

Browser tools have limits. Compression results vary by file content, official identity-photo requirements must be checked with the issuing authority, and PDF operations may not support encrypted documents.

How we describe tool results

FileFit focuses on explaining what a browser-based result does and does not mean. An upload-readiness PASS confirms the selected technical rule, not acceptance by a receiving portal. Scan-quality warnings are visual heuristics; they do not establish document accuracy, authenticity or legal validity. Users should always inspect final files before submitting them.

Why we publish practical guides

Real upload requirements combine file type, size, pixels, PDF pages and document-specific checks. Our free preparation guides show the order in which to solve these problems and explain when a separate review is still necessary. We aim to keep the instructions accurate as browser tools are refined, and welcome specific bug reports through our contact page.
