Every study below states its method, its fixtures, its browser and its date — and where there's a dataset, you can download the raw CSV/JSON and check our arithmetic. Reuse anything with a link and the measurement date.
| Study | One-line finding | Data |
|---|---|---|
| Browser File-Converter Privacy Benchmark | Popular converters load up to 24 third-party hosts and 5 trackers before you drop a file; one ships 661 KB of session-recording telemetry. Local converters: 0–3. | CSV · JSON |
| JPG vs WebP: quality vs size | WebP saves 26–61% at equal settings; quality 100 is a trap (5–11× size jump from 90). | table |
| What happens to EXIF when you convert | Canvas re-encoding strips all metadata structurally; our keep-toggle restores the original APP1 byte-for-byte (+67 B), orientation-corrected. | table |
| Don't trust "no upload" — verify it | The 3-minute network-tab check anyone can run, and the automated version our test suite enforces on every build. | guide |
