Honesty & reputation · 90/100 · 30%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Pricing transparency | 33 / 35 | 100% free and login-free on the web, and honestly reports "The compressed file is reduced 0.08 %" on the result page without faking numbers or adding a paywall (01_landing.png, 02_workspace.png, 03_result.png). | Evidence A → |
| Interaction restraint | 27 / 30 | Direct download without registration plus an instant server-file delete button and zero pop-up traps. | Evidence A → |
| Background & reputation | 16 / 20 | Operated since 2017, offering 44 free online PDF utilities alongside Windows and macOS desktop apps. | Evidence A → |
| Engineering & privacy | 14 / 15 | Provides an immediate trash-icon delete button on the result page and automatically purges remaining files after 30 minutes. | Evidence A → |
Capability · 66/100 · 70%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Task quality | 38 / 65 | Deterministic PDF stream inspection: preserves 100.0% of all 27 native vector text operator blocks (BT/TJ), 4/4 headings, and 12/12 table cells, but fails to recompress or downsample the embedded FlateDecode raster stream, leaving file size virtually unchanged at 1,657.7 KB (-0.08% reduction, 1.00× ratio) (38.0/65) | Evidence A → |
| Deliverable specifications | 14 / 20 | Watermark-free and login-free, but produces negligible size reduction on PDFs containing FlateDecode raster streams (14.0/20) | Evidence A → |
| Processing speed | 14 / 15 | Server processing finishes in 2.35s (14.0/15) | Evidence A → |
Legacy scores may include advertised maximum capabilities. Read tested output separately from paid capabilities. Records without matching tiers and scope are not ranked together.
