1. Functional checks
Each tool is tested around its primary workflow: selecting or dropping a file, processing it, handling unsupported input, resetting the state, and downloading the finished result. We also review keyboard-accessible file selection and responsive layouts because a tool that works only with one mouse/browser combination is not ready.
2. Output checks
Compression
We compare source and result byte counts, verify that the output opens, and check whether a requested target was actually achieved or clearly reported as unrealistic.
Privacy Blur
We verify that selected regions are rendered into the exported image and that the downloaded copy can be opened independently from the editor.
MarketReady
We verify canvas dimensions, crop/placement behavior, and exported image readability.
File Opener & Translator
We distinguish successful decoding/extraction from formats or text that the browser/provider cannot reliably interpret.
3. Privacy-boundary checks
For browser-local tools, we design the processing path so the selected file can be handled on the device. We document exceptions instead of hiding them. Image Translator is the current mixed workflow: OCR/image work occurs in the browser, while recognized text can be sent to the configured translation provider. Analytics, consent, advertising, and ordinary page resources are separate network activity described in the privacy and cookie policies.
4. Controlled reference tests
When an article makes a statement that benefits from a concrete example, we prefer a reproducible test over a vague claim. The first public set is the Fitabyte Lab format reference, which uses deterministic synthetic images and publishes the exact byte counts for several encodings.
5. We document limitations
Browser capabilities vary. Media processing can be memory-intensive. PDF compression can flatten pages and remove interactive/searchable features. Automatic OCR and translation can misread names, codes, dates, or high-stakes text. Privacy Blur is manual and cannot know which detail you forgot to cover. A useful tool page should state those limitations before a user depends on the output.
6. Editorial review
Guides are written to solve a specific file problem, reviewed against the actual Fitabyte behavior, and updated when a tool or platform assumption changes. We avoid inventing universal quality scores or claiming that a file target is appropriate for every use case. Read the Editorial Policy for the publishing standard.
